SEGFAULT's tremulous gpp fails also, but GPP works...

Hmm I think something happened to 32 bit applications support on my system, coz x86_64 works (of GPP)

Hm, perhaps. See if compiling from source helps. http://unvanquished.net/wiki/index.php/ ... the_source

Will try later;

So the problem is when after initializing SDL the program skips initialization of OpenGL. But why there is no detailed error message when program chooses to NOT initialize OpenGL? That sure seems like an error/warning :) From above logs:

1) SDL using driver "x11"
Initializing OpenGL display
Estimated display aspect: 1.600 ...setting mode 1920x1200 Using 4/4/4 Color bits, 16 depth, 0 stencil display.
(WORKS)

2) SDL using driver "x11"
...setting mode 1920x1200
Couldn't get a visual
GLimp_Init() - could not load OpenGL subsystem

Could we change Unva to log details why it decided to not initialize OpenGL after starting SDL? Probably it tests for some lib and it fails. Show this, and show error codes/messages from OpenGL/system too.

At least for Unvanquished, it could be a glew issue. Are you using the precompiled linux packages?

epicdude · Post by **epicdude** » Thu Nov 08, 2012 7:31 pm UTC

Yes the precompiled. Not the .deb file but unpacked some file with binaries afair...

Can you add more debug code around OpenGL init and make sure all error numbers + messages are visible? And package that at some point?
