I recently installed Steam, and bought a few games, mainly to show support for games being ported to linux.
My problem is as follows:
My computer has an ATI mobility radeon HD 3400 video card, running on open source drivers. The games won't run when i try to run them(Faster Than Light crashes the system, The Cave just won't start). When i use the integrated intel chip as defaut graphics, this problem does not occur.
I previously tried to install proprietary drivers for ATI, but that was a disaster, so i reverted back to open source drivers
If anyone knows the reason for this error, and perhaps a solution for it, please share your info. [EDIT]: I am using Ubuntu 12.04 LTS 64-bit
