RE: [LI] X-windows on clients
You can run X-window on client (win 98/NT) Software called MIX need to be
installed on to client's m/c
after installing it, run Mix and telnet to your Linux server and type
export DISPLAY="YOUR M/C IP ADDRESS":0.0
press Enter
type xterm
<<The MI-X FAQ.txt>>
you get a different terminal wherein you type :'kde' or 'gnome -session
if if worked let me know.

The MI/X FAQ
The MI/X FAQ
Some of the questions and answers below pertain only to the Windows® or the
MacTMOS platform. This is indicated by (Windows) or (MacOS) being placed after
the "Q:" If there is no such indication, assume that the question is pertinent
to any platform.
Q: Is MI/X really free?
A: Yes. No strings attached. MicroImages does retain a copyright on it,
however.
Q: Why is it really free?
A: MicroImages gains name recognition and good will. MicroImages maintains
MI/X as the X Server for its professional TNT image processing, geospatial
data management, and desktop cartography products. In order to make the
TNT products work exactly the same on all Windows, Macintosh and UNIX
computers, MicroImages needed a robust and stable X Server whose future
was not in the hands of some other company. (MicroImages also enjoys the
irony that some ARC/INFO users will run our competitor's product on our
free X Server.)
Q: What good is an x-server? What can I use it for?
A: Using MI/X, you can run a UNIX program remotely on the UNIX machine
itself, sending the display output to MI/X on your local PC or Mac.
Q: How can I get a copy of MI/X?
A: You can download it from MicroImages' FTP site, or from mirror sites.
The URL to download MI/X from MicroImages' is http://www.microimages.com/
in the "Free Downloads" section.
Q: Can I mirror MI/X on my FTP site?
A: Yes. We do ask that you agree to the following few conditions:
The files you distribute must be unaltered copies of the package as
distributed by MicroImages, Inc.: this is to include the binary
executables as well as any configuration files and text files contained
with it.
Please register your mirror site with MicroImages, so that we know about
the mirror and can point others to it, and can keep you informed on
changes in the software. You can register online at this URL:
http://www.microimages.com/freestuf/mix/register.htm
You may not reverse engineer, or convert into any human conceivable
form, the binary executable files that make up MI/X.
You may not charge money for MI/X itself, excepting the costs of
redistribution media or shipping.
Keep up with the latest version. Please check back with us as we update
our products quarterly, there are likely to be some improvements made in
MI/X that you will want to make available as well.
Q: When I click on the links on your download page, I get an error message
saying that the file doesn't exist or that the link is no good. What is
wrong?
A: The links aren't bad. Some browsers will return an error message
indicating that the link is bad or that the file wasn't found, when in
fact, the browser times out because the site is so busy.
Q: I'm having trouble downloading MI/X. Can you e-mail it to me?
A: No. If you are having trouble downloading, try again at a different
time, or try a mirror site. MI/X is popular and traffic is heavy, which
can cause download problems during peak periods. Attempting to email it
would only consume our valuable staff time and would not evade such
problems as network traffic or slow connections. If you don't have a good
enough network connection, then we encourage you to order TNTlite on
CD-ROM from MicroImages, which includes MI/X, and which you can obtain for
costs of shipping and handling. Ordering the TNTlite on CD gives you
access to our award-winning geospatial data analysis software, and many
Getting Started tutorial booklets with sample data, as well as Adobe
Acrobat Reader for various platforms. It is well worth the investment!
Q: Are there any manuals or documentation available for MI/X?
A: The FAQ is the only documentation available for MI/X.
Q: Is MI/X implementing X11R5 or X11R6?
A: The Windows version is X11R5, the Mac version is X11R6.
Q: Is it possible to submit reports of possible errors or ask for new
features for MI/X?
A: Yes. Please keep in mind that MI/X was designed to provide a cross
platform interface for our professional GIS software, TNTmips. We have
provided it free to those who may also find it useful. Development of MI/X
will be driven by the needs of TNTmips and our clients who use TNTmips.
Any errors or features that don't affect or aren't required by TNTmips or
our clients will be given a very low priority.
Q: (Windows) I've downloaded all the files for MI/X for Windows, how do I
unpack it?
A: Make sure that all the files are in the same directory, (don't put any
capital letters in the name and don't make its name longer than 8
characters) then type GETME1ST.EXE to start unpacking the files. This will
make a bunch of new files, one of which is called "SETUP.EXE." To continue
the installation, type SETUP.EXE and follow the instructions on the
screen. On older versions, the setup program for TNTlite and MI/X is the
same, during install it will bring up a list of files that are missing. By
each file is a letter that indicates what it is a component of. As long as
no X's (to mark Xserver files) appear, you have all the pieces you need
and can proceed with the install.
Q: (MacOS) I've downloaded MI/X for MacOS, how do I unpack it?
A: You will need a decompression utility. One of the most popular
utilities is called StuffIt Expander. Drag the file you've downloaded on
to the StuffIt Expander icon, and that is all you need to do.
Q: (Windows) When I try to run the setup program created from getme1st.exe,
I get an error message saying "can't find file0001.bin". What's happening?
A: file0001.bin isn't in the same directory as setup.exe, or it was
renamed to something other than file0001.bin, or you didn't download the
file. Note that sometimes some browsers have been known to change the name
of the file when you save it to your disk. If the name of file0001.bin is
changed to anything different, setup.exe will not find it, and your setup
will obviously fail.
Q: (Windows) When I downloaded file0001.bin, it was renamed to file0001.exe.
I renamed it to file0001.bin, but setup still can't find it. What should I
do?
A: What is probably happening is that you have Windows Explorer set to not
show the extensions of known file types. If that is the case and you
attempt to rename the file using explorer, what you will end up with is
file0001.bin.exe. The quickest way to solve this problem is to go to a DOS
prompt and rename the file there, e.g.:
C:\>rename file0001.exe file0001.bin
Q: (Windows) When I run setup.exe, my system goes into DOS and then hangs.
A: Please take the following steps to correct the problem;
Under Windows '95, right click on the Start button and select the
Explore option.
Double click on the Programs group.
Right click on the MS-DOS shortcut and select Properties from the drop
down menu that appears.
In the MS-DOS Prompt dialog window that opens, select the Program tab
and then click on the Advanced button at the bottom of the dialog
window.
In the Advanced Program Settings dialog that opens, make sure that one
of the two choices other than MS-DOS Mode is selected.
Click OK and OK to exit the Advanced and MS-DOS Prompt dialog, close the
explorer and try the install process again.
Q: How do I uninstall MI/X?
A: Delete the directory that MI/X is installed to.
Q: (Windows) I downloaded the installation files for Windows 95 and ran the
setup.exe. After selecting 'install/setup mi/x server with twm' dialog box I
received the message: "Unable to update tntproc.ini." Then the install
ended. Any suggestions?
A: Install MI/X into a directory that doesn't have a space in the path
name, (i.e. don't install to a directory under c:\program files) and make
sure the pkunzip.exe created by getme1st has the correct filename:
pkunzip.exe, and not pkunzip.bin or something else.
Q: (Windows) MI/X seems to install correctly, but when I try to launch it I
get a "not enough memory..." error message. What can I do?
A: Install MI/X into a directory that doesn't have a space in the path
name, (i.e. don't install to a directory under c:\program files).
Q: (Windows) How do I start the MI/X program after installing it?
A: You can start MI/X from the "Start" Menu (Start / Programs / Free
TNTlite products / MIXServer ) which runs a program called TNTstart to
launch MI/X, or you can change to the directory where MI/X is located and
type 'tntstart startmix' . (Note there is a space between tntstart and
startmix). In some rare cases using the TNTstart program to launch MI/X
does not work. In those cases issue the following commands from a DOS
prompt (you cd to the directory where you installed MI/X):
XS
TWM
This will start the server and its window manager manually. Running the
commands from the command line can also be a good way to trouble shoot
since you may get error messages reported to the console that may help you
discern what is going wrong. You would not see these if you were running
the program using tntstart.
Q: When starting MI/X, I see the MI/X screen come up briefly and then goes
away and then I get an error message. What is happening?
A: Connect to the machine that you want to run MI/X against before you
start MI/X.
Q: When I start MI/X, a warning message comes up saying I need 256 colors,
what do I do?
A: If you are running your computer/monitor in a color mode with less than
256 colors, MI/X will not work. If you want to run MI/X, you will have to
change the color mode to 256 or more colors.
Q: When I start MI/X, all I get is a big blue screen. How do I make my
remote connection?
A: You have to establish your remote connection outside of MI/X. Windows
comes with a telnet utility and they are also available for the Mac.
Q: I login to my remote UNIX host. Then I start MI/X and it comes up okay.
Then when I try to start an X session, or send a remote X client to the
machine running MI/X, MI/X quits. It does this every time. What am I doing
wrong?
A: Try changing your preferences. For Windows, edit tntserv.ini and make
sure that CloseOnMenuExit is set to No, e.g.
CloseOnMenuExit=No
For the Mac, open File / Preferences, select the "Preferences" icon on the
left, and make sure that the "Auto exit when last client dies" checkbox is
not checked.
Q: (MacOS) When I try to start MI/X I get a message saying "unable to open
:0.0". What is going on?
A: Make sure that under the "Sharing Setup" control panel the Macintosh
has been given a name.
Q: (Windows) The x-term windows that open in MI/X go to the top left hand
corner of the MI/X window and I am unable to move them. What can I do?
A: This happens when you launch MI/X without launching twm. Use tntstart
startmix to launch MI/X. (note the sapce between tntstart and startmix) If
you are using a shortcut, set the target to
C:\MIX_95\TNTSTART.EXE startmix
substituting the actual path if you did not install MI/X to the default
directory.
Q: (MacOS) The x-term windows that open in MI/X go to the top left hand
corner of the MI/X window and I am unable to move them. What can I do?
A: This happens when you launch MI/X without launching twm. Check your
preferences and ensure that Use Local Window Manager (twm) is checked.
Q: Can I use a window manager other than twm with MI/X?
A: Yes, however twm is the window manager we support. We can't tell you
how to configure other window managers, or even guarantee that they'll
work.
Q: (MacOS) How do I configure twm?
A: If you put a file named "system.twmrc" in the same folder as the twm
program on your computer, the twm program will read configuration settings
from it. Consult the documentation, man page, etc. for twm to learn what
to put in system.twmrc to configure twm. Note that the current version of
MI/X for MacOS does not support the launching of X clients from a twm
menu. This may be forthcoming in later versions.
Q: (Windows) How do I configure twm?
A: The MI/X distribution comes with a file named TNTSERV.TWM. This is
twm's configuration file. To learn the format of TNTSERV.TWM, consult the
documentation, man page, etc. for twm. If you wish to create a custom
format for twm, you can make a configuration file with any name, and
direct twm to use it instead of its default configurations. This is done
by using the -f option, i.e. twm -f myconfigfile.twm
Q: (MacOS) I've made an unfortunate configuration change that causes MI/X to
hang, now each time I try to start MI/X, it crashes without even letting me
get to the Preferences dialog to fix the configuration. What do I do?
A: If you hold the <COMMAND> key while double-clicking the MI/X
application icon, MI/X will open the Preferences dialog for you without
launching the X server. You can then undo any unfortunate configurations.
Q: How do I use MI/X to start an X session with a remote host?
A: Start MI/X. Telnet to the remote host. Set the DISPLAY environment
variable on the remote host to the machine you are running MI/X on. For
example on Solaris (running csh):
setenv DISPLAY mymachine:0.0
or failing that:
setenv DISPLAY my.machine's.ip.number:0.0
(running BASH):
export DISPLAY=mymachine:0.0
or failing that:
export DISPLAY=my.machine's.ip.number:0.0
replacing "my.machines's.ip.number"
with the actual IP number of the local machine running MI/X.
After this, you can launch whatever X applications
you wish on your remote host and they will display on the machine running
MI/X. To invoke a command shell try:
xterm &
When the xterm comes up you can close the
telnet session. The commands may differ on various flavors of UNIX.
Q: I've set my display correctly and I know I'm using the correct IP number
because I know it or I used winipcfg.exe to find it when it is dynamically
assigned, but I am still getting a "can't open display" error message. What
now?
A: If you are following the procedure outlined in this FAQ and you are
still getting this error, contact the sysadmin of the remote host, the
sysadmin of the system you are using or tech support for your ISP and ask
if the systems that you are going through allow x-traffic to pass through.
Some of them don't.
Q: What fonts can I use with MI/X?
A: BDF and PCF fonts.
Q: There are a lot of fonts included in the distribution that I won't use
and are taking up space on my hard drive (such as Chinese and Japanese
character fonts.) Can I get rid of some of these fonts and still use MI/X?
A: Yes, you can get rid of some of the extra fonts. Of course, you will
still need to keep some of them. Here are some examples of fonts to keep:
7x13b.bdf -misc-fixed-bold-r-normal--13-120-75-75-c-70-iso8859-1
ascii.bdf -mi-fixed-medium-r-normal--16-160-72-72-c-160-ascii-1
olcursor.bdf -sun-open look cursor-----12-120-75-75-p-160-sunolcursor-1
olgl10.bdf -sun-open look glyph-----10-100-75-75-p-101-sunolglyph-1
cursor.bdf cursor
deccurs.bdf decw$cursor
decsess.bdf decw$session
The last part of the font is the language encoding. Chances are that if it
isn't "iso8859-1", then you don't need it. Exceptions are the other files
above. "cursor.bdf" is especially important as it contains the cursors
used by the X Window System.
Q: The fonts that I need to run my program aren't included in with MI/X.
Where can I get more fonts?
A: Check with your sysadmin, or take a look on the web. Here is a site
that I found:
http://www-rn.informatik.uni-bremen.de/home/X11R6/lib/X11/fonts/100dpi/
http://www-rn.informatik.uni-bremen.de/home/X11R6/lib/X11/fonts/75dpi/
http://www-rn.informatik.uni-bremen.de/home/X11R6/lib/X11/fonts/misc/
Q: I've got all the standard X fonts here, but in the PCF format. Are these
compatible with MI/X, or do they need to be in the BDF format? And how do I
tell MI/X to add them?
A: Yes, you can use the PCF format. Find the BDF/MISC directory (it should
be in the directory into which you install MI/X), there should be a file
called "fonts.dir" which contains examples of how to add BDF and PCF
fonts. The "fonts.dir" file for MI/X corresponds to the file with the same
name on a UNIX X server.
Q: Okay, I understand that to add a font, it has to be in a *.bdf or *.pcf
format and that they have to be added to the fonts.dir, but how do I do
that?
A: First, open the font in a text editor. The first few lines will look
like this:
STARTFONT 2.1
FONT -Misc-Fixed-Medium-R-Normal--10-100-75-75-C-60-ISO8859-1
SIZE 10 75 75
Copy the line that appears after FONT. Next, open the font.dir file with a
text editor. It will look like this:
87
gb16.pcf -cclib-fixed-medium-r-normal--16-150-78-78-c-160-gb2312.1980-0
ascii.bdf -mi-fixed-medium-r-normal--16-160-72-72-c-160-ascii-1
7x13b.bdf -misc-fixed-bold-r-normal--13-120-75-75-c-70-iso8859-1
Note that there is a number at the top of the file. This has to match the
number of fonts in the file. (I've only included the first three in this
example. The actual file would have 84 more entries.) Once the fonts.dir
is open, go to the bottom of the file and add the name of the font you are
adding and paste in the information you copied from the font. Then change
the number at the top of the file to reflect the new number of fonts in
the file. In my example, I would change 87 to 88.
Q: How can I delete fonts?
A: Follow the steps mentioned above for opening the fonts.dir file, delete
the entry for the font you are deleting, change the number at the top of
the font.dir file to reflect the correct number of fonts listed in the
file. Save the font.dir file and delete the *.bdf or *.pcf file.
Q: Can I use a fontserver for MI/X?
A: No. Fonts have to copied to the machine running MI/X.
Q: (Windows) Why can't I use the ALT-GR key sequences (for European
characters) with MI/X?
A: MI/X doesn't support the ALT-GR key sequences. Some clients have
reported success using the ALT-GR key sequences after using the xmodmap
utility to remap their keyboard once the remote connection has been made.
The following was submitted by a client, and was reported to work rather
well.
Activation with 'xmodmap .xmodmaprc'.

Q: (MacOS) When I launch MI/X I get the following sequence of dialogs,
what's wrong?
Warning: STARTFONT 2.1 Comment $XConsortium: 6x13bdf, v1.13
92/04/02
14:24:50 gildea ....
Warning:
Warning: file bdfread.c;line 529# bad startfont
Error:fatal: Could not open default font 'fixed'
A: It could be a couple different things:
Don't move the fonts to your system folder. Leave the fonts in the
location that the install process puts them.
Some versions of Expanders for StuffIt archives by default will convert
the linefeeds in text files to Mac format. This will cause MI/X to
report an error when reading the fonts.dir or fonts.alias file. To get
around this, you will have to temporarily change the Expander program
preferences to not convert text files to Mac format.
Q: (Windows) I don't have a three-button mouse, but I need three buttons for
my X clients. How do I do this?
A: Currently, if you want to have three buttons for your X clients, you
need to have a three button mouse on your PC. There is no key sequence or
shortcut to emulate a third button on Windows like there is on the Mac.
If you want to use the paste/insert text function in X which is by default
mapped to the middle button which is unavailable on the PC, then there may
be a workaround: You can use the xmodmap program to modify how the mouse
events from the server (MI/X) are interpreted by the X client (i.e.
xterm). For instance you can swap the middle and right mouse button with
this command:
xmodmap -display mix.machine.name:0.0 -e "pointer = 1 3 2"
That will make the right mouse button act like the "middle" button of a
three-button mouse, thereby allowing selecting and copying text with the
left button, and pasting/inserting with the right button. Note that on a
two-button mouse you will still be missing a button (the button that was
the right button, or button 3): you just switched around what button does
what using the xmodmap program. So if you need true three-button
functionality, the best solution is still to get a three button mouse.
If you have a three-button mouse and can't get the buttons to work
properly, make sure that you have drivers properly installed and
configured for the three-button mouse so that Windows can handle three
buttons instead of the default two. Specifically, you will need to tell
the driver that the middle button of the mouse is to be mapped to a
"Middle Button" function, and not to some other nifty (and tempting)
Windows shortcut. Note that if you do this, the "Middle Button" function
will not used under Windows itself, but will be accessible to MI/X and
clients running in it. Logitech provides three-button mice and drivers
that work and have been tested with MI/X. Also, the Intellipoint mouse
sold by Microsoft offers a rolling wheel that acts as a scroller
controller on the mouse when turned while in Windows applications, and
when clicked, it can be set to function as a "middle" mouse button which
works in MI/X.
Q: I get a Bad Length error message when I'm trying to run a program through
MI/X. What can I do to correct this?
A: This error occurs when the UNIX box that MI/X is running against
attempts to pass an image that is at a greater bit depth than the display
of the local machine is set to. For example, if you are running MI/X on a
Windows machine set to display 256 colors (8-bit) and the program you are
running tries to pass a 16 bit image, you'll get this error. To correct
this, set the parameters of the program you are running to match the
resolution of the local machine, or change the resolution of the local
machine to match the bit depth of the images that the UNIX box is trying
to pass.
Q: When I use a pop-up menu in xterm, scrolling through the menu text causes
it to disappear. Is there a fix for this?
A: This is a known error, but there is no fix for it.
Q: Does MI/X support xauth, or is there some other means of limiting what
users can use it or what applications they can open?
A: No.
Q: (Windows) Can I run the X11R6 executables that have been ported to
Windows NT?
A: Yes. Make sure that your DISPLAY environment variable points to the
machine running MI/X, i.e. set DISPLAY=hostname:0.0 You can then run
xclock, oclock, etc. on a PC running NT or 95 instead of using a remote
UNIX host.
Q: (Windows) It seems that MI/X always takes up the full screen when it is
launched. Is there a way I can set the screen size for MI/X?
A: Yes. Edit tntserv.ini and add the following entries under the
[XSERVER] section
NumColumns=n
NumRows=n
with n being the number of rows and columns you want MI/X to occupy.
Q: (MacOS) It seems that MI/X always takes up the full screen when it is
launched. Is there a way I can set the screen size for MI/X?
A: No.
Q: (MacOS) Is it possible to run MI/X in rootless mode?
A: No. You can access your desktop when MI/X is running by going to your
application menu and selecting Hide TNTx or bring Finder to the front and
Hide Others.
Q: Can I cut and paste with MI/X?
A: MI/X will support cut and paste of text to other X applications, but
not graphics.
Q: Can I cut and paste between MI/X and a Windows or Mac application?
A: No.
Q: Can I use MI/X to run UNIX programs locally on my Windows or Mac
computer?
A: No. Using MI/X, you can run a UNIX program remotely on the UNIX machine
itself, sending the display output to MI/X on your local PC or Mac. You
cannot however download a program compiled for UNIX and attempt to run it
on your Mac or PC using MI/X (or anything else for that matter). If you
have X programs compiled for your Mac or your PC, then yes, you can use
MI/X as the graphical X environment for these programs. That is why we
created MI/X in the first place!
Q: Can I use MI/X to run programs remotely on my Mac or PC and display the
output on a UNIX machine?
A: No.
Q: Is there a way to use XS to do a rsh or rexec directly to the station I
want to login to?
A: No. The MI/X distribution does not include an rsh or rexec client. You
can obtain rsh or rexec clients from other sources.
Q: (MacOS) Does MI/X support dual monitors?
A: Yes, as of the 21 Aug 1997 version. Previous versions do not.
Q: Is MI/X capable of xdm queries?
A: No. Although there may be options and preferences to set regarding xdm,
they have not yet been implemented.
Q: (Windows) Do you have a version of MI/X that will run on a Windows 3.1
machine?
A: Yes and No. Actually there is a version of MI/X for Windows 3.1: it is
shipped with our software for Windows 3.1. However, you cannot use this
version of MI/X as an X server for clients run on a remote host. This is
possible on Windows95/NT and MacOS because MI/X uses sockets technology
available in those operating systems, which is unfortunately, not
available in Windows 3.1.
Now, if you have a bunch of local X clients (such as TNTlite which you can
also download for free at http://www.microimages.com/freestuf/), MI/X for
Windows 3.1 will be useful to you. But if you're hoping to use your
Windows 3.1 box as an X terminal using MI/X like you would on Windows 95,
then sorry, you're out of luck.
So, if you mean, "Can I use MI/X as an X server for clients on remote
machines accessed via a network?", then, no, MI/X for Windows 3.1 does not
support this feature. Therefore, we do not package MI/X separately for
distribution for Windows 3.1 as we do for the Windows 95, Windows NT, Mac
68k or Mac PowerPC version of MI/X. This is just one of many reasons that
MicroImages recommends that users of Windows 3.1 upgrade to Windows 95.
Q: Do you make the source code for MI/X available?
A: No.
Q: Are there any plans to support the LBX (low band width) extension?
A: No.
Q: (Windows) Is it possible to run MI/X on my Windows 95 machine to access
the binaries on a Linux box using a serial (nullmodem) cable.
A: Yes, if you are using the null modem cable to establish a TCP/IP
network between the machines. However it will be limited to the speed of
the communications. This is really no different than using serial to talk
to a modem to talk to another machine to establish TCP/IP.
Q: (Windows) Is there a way for me to determine what my IP address is when
I'm connecting to a UNIX machine through a modem?
A: Yes. For Windows 95, after connecting, run winipcfg.exe (it's a Windows
utility that is in the directory that you have Windows installed to) It
will tell you what IP address has been assigned to your computer. For
Windows NT, open up a separate command shell and run the ipconfig.exe
program. It must be run in a separate shell because if you use the
"START/RUN" menu the output will flash briefly and then go away. Use the
IP number to set your DISPLAY, for example: setenv DISPLAY
198.247.245.38:0.0.
Q: When running a graphics intensive application through MI/X, I get error
messages or the graphics don't display correctly. Is there a way to correct
this?
A: Try setting your local display to 256 colors (8 bit).
Q: Does MI/X support psuedocolor?
A: Yes, if your local display is set to 256 colors (8 bit).
Q: Does MI/X support DirectColor?
A: No.
Q: Is there a way to start my x-term with a white font color and a black
background?
A: Yes. Start the x-term as follows:
xterm -fg white -bg black
Q: Can I change the bit depth that MI/X is running at to something other
than what my local machine is running?
A: No. There is a work around, if you have Microsoft's Power Toys
installed. You can use quickres to set your display to one bit depth,
launch MI/X, minimize MI/X and then use quickres to change the bit depth
of your display to something else. This isn't something we recommend, but
some users have tried it with success.
Q: Is MI/X available for the Windows NT running on a DEC Alpha?
A: No.
Q: (MacOS) My key combination "control-\" doesn't seem to work correctly.
A: This is a known error. There is currently no work around.
Q: Does MI/X support openGL?
A: No.
Q: Java programs on SGI, Sun, and DEC machines crash when trying to use MI/X
as their X server. is there a way to correct this?
A: The problem occurs because the Motif AWT libraries use the Font "plain
Dialog 12 point" as a fall-back default font. Unfortunately, when using a
remote X server sometimes this font isn't available.
The problem is common enough to be included in the Java Programmers's FAQ
(http://www.best.com/~pvdl/javafaq.txt):
4.2 Why do I get this when using JDK 1.1 under X Windows?
java.lang.NullPointerException
at sun.awt.motif.MFramePeer.<init>(MFramePeer.java:59)
at sun.awt.motif.MToolkit.createFrame(MToolkit.java:153)
at java.awt.Frame.addNotify(Frame.java)
at java.awt.Window.pack(Window.java)
A. There's a missing font on your system. Move font.properties from the
"lib" subdirectory aside to font.properties.bak Then it won't look for
the font and fail to find it.
Once this fix is in place, MI/X works well with Java clients running on
Sun and SGI.
Q: (MacOS) MI/X Was working before and I have upgraded to System 8.5 and now
MI/X hangs?
A: Due to changes done by Apple for MacOS 8.5, it is necessary to download
a newer version of MI/X for the Macintosh. The version date for MI/X to
run correctly on MacOS must be later than October 20, 1998 .
