Why the Linux version of UnrealTournament crashes (signal 11) using the
OpenGL or SDL driver

If you have the problem of the title (I had this problem with my Nvidia
driver), don't worry because it is incredibly simple to solve.

First of all go in /usr/lib and check the libGL.* files:


[root@xp lib]# ll libGL.*
lrwxr-xr-x    1 root     root           17 2003-08-12 11:38 libGL.so -> libGL.so.1.0.4496
lrwxr-xr-x    1 root     root           17 2003-08-12 11:38 libGL.so.1 -> libGL.so.1.0.4496
-rwxr-xr-x    1 root     root       423476 2003-08-12 11:38 libGL.so.1.0.4496


Now look at your UnrealTournament.ini file located in ~/.loki/ut/System
and go in the sections [SDLGLDrv.SDLGLRenderDevice] and
[OpenGLDrv.OpenGLRenderDevice] of the this file.
Here you will find the followin option in both the 2 sections:

OpenGLLibName=libGL.so.1

Well now what you must do is simply to substitute the current value of
the option with the file linked by libGL.so.1.
In my case I have that libGL.so.1 is a simbolic link to
libGL.so.1.0.4496 that is the real library, so I must simply set
OpenGLLibName as the following:


OpenGLLibName=libGL.so.1.0.4496


Practically seems that UT doesn't like simbolic links or something
similar.
Now launch the game and play this fantastic game!
