Hey folks, i'm not sure if this is the right forum to post, but my research has led me to believe that. If it should turn out that this i just forgot to switch on some obscure options, or it is actually the games' bugs, then feel free to move this thread.
I'm currently running Ubuntu Jaunty with stock kernel (2.6.28-15, x64) and opensource radeon drivers & graphics stack from the xorg-edgers ppa, on a 64-bit system with a Radeon X1600 w/ 256 MB RAM.
Openarena, compiz and the demos of ballistics and Postal 2 work like a charm, but the game that brought me to the whole thougt of playing on linux is hanging
When i try to start the demo version of LGP's X2 port, i see the loading screen, then it turns blank, i hear the sounds of LGPs "intro movie", then silence and blank screen for 1-4 seconds, and then the game segfaults with a message like this:
for two times in my hours of random trying, i achieved to see the following loading screen before the segfault. LGPs testtool gives some interesting results, though:
x2-demo 1.4.05, built for i386
Segmentation Fault: What do you mean mind the asteroid? What astero
This is a BUG, please report it to http://support.linuxgamepublishing.com
note the "direct rendering: No", whereas glxinfo returns

the syslogs also show nothing suspicious. Results are the same with stock graphics stack.
I think i have installed all the necessary libraries for running 32-bit apps on 64-bit systems, as well as all the old libraries required by LGPs installers (the script getlibs was a great help).
However, the demo runs fine (well, at slideshow-speed, but playable) on my EEE pc 4G, which has its integrated Intel graphic chip, an even older kernel and a 32-bit system.
My questions now are:
1. From my limited knowledge, a segfault often points to a memory problem. Could a custom compiled 2.6.31 kernel with enabled GEM/TTM bring help?
2. Could this segfault be a result of some animosity between 32-bit app and 64-bit system? i have 8 GB RAM installed, so perhaps there lies a source of trouble.
3. Could it be that the drivers' OpenGL implementation (somewhere at OpenGL v. 1.4 IIRC) just not yet fulfils the games' needs?
4. Might there be some arcane option in the xorg.conf or elsewhere, for direct rendering, shadowfb or something else? currently my xorg.conf has no customized entries.
Any hint is appreciated
