[Ltsp-discuss] Re: GLX on low end workstation

XF4 has software GLX available if you request it in the config.
file: /usr/X11R6/lib/modules/extensions/libglx.a
cfg: Load "glx"

XF3 can accept the utah-glx project. This provides software GLX
and also has hardware acceleration available for some chipsets.
http://utah-glx.sourceforge.net/
If you fetch the project's source code, you can compile a software only
version of the GLX driver (which is basically X-server side Mesa) and serve that out to all your clients. That should solve your problem.

I have a wide mix of hardware, so I have a second version next to that.
This has all the hardware acceleration support compiled into the driver
and is thus much much bigger, slower to download and slower to start up.
The X script uses the first one unless the LTSP config file indicates
that this terminal might have hardware accelerated 3D available.

Remember: You need to modify the script that writes the X config file so that it only lists the GLX support if the client that is running the script has successfully managed to get swap running (check swapon -s).
Otherwise, you'll get random display crashes (when Mesa needs memory).
