please post your system information from the steam client. it's under help -> system information
This is not a bug, you’re running the shell script without the needed commands; Steam is already loaded, you can simply press the PLAY button, or use steam steam://run/240 in a launcher.
If you insist, ./hl2.sh -game cstrike -steam will run the game, but you need to use LD_PRELOAD="~/.steam/bin/gameoverlayrenderer.so" to get the overlay loaded etc, its more hassle.
__GL_THREADED_OPTIMIZATIONSx1 2013-02
I'm having extreme issues with Counter-Strike: Source - upon loading it immediately crashes.
Running ~/.local/share/Steam/SteamApps/greyjanthesane/Counter-Strike\ Source/hl2.sh returns this error:
I've tried editing hl2.sh and setting __GL_THREADED_OPTIMIZATIONS to 0, to no effect.
My graphics card is an SAPPHIRE Radeon HD 7770 GHz Edition (1GB GDDR5), running Ubuntu 12.10 (up-to-date)
