I'm trying to start NS2, and it loads the loading screen, then it starts bouncing between showing the loading screen and a blank screen until finally it quits out / crashes compiz. This is due to the graphics card trying to reset itself.

I'm running Ubuntu 14.04 and have tried it with the latest git mesa/kernel as well as stock.

I've reported it to launchpad and to mesa.

The NS2 specific log file doesn't seem to have anything useful.

    Any chance you can get gdb attached and get a trace when it crashes?

    I would also try removing your shader cache (~/.config/Natural Selection 2/cache) and system_options (~/.config/Natural Selection 2/system_options.xml)

    I want to say tuxator has had issues with this for a few days.

    When I run "ps -e| grep ns2_linux32" I get two or even three ns2_linux lines.. Which one should I attach gdb too?

    could you check if there is something printed to dmesg (just type 'dmesg' in a terminal after the game crashed. Maybe your eyes can spot something related to a crash) or syslog (tail -20 /var/log/syslog should do the trick)? If something crashes it usually leaves something in one of those two logfiles.

    Also you could try and toy around with mesa/gallium -> http://www.mesa3d.org/envvars.html (I'd start with setting MESA_DEBUG and MESA_LOG_FILE and exporting them so that they're known system wide, that way you don't have to start the game from console).

    Just for your information: I've a Radeon HD5870 and I'm using the same driver/operating system (using the Gnome edition) as you do. For me the game works (more or less).

    I ended up switching video cards.
