CS:S & Team Fortress 2 won't start

[Artheg]

When I try to start any of subj. games I see black screen for a moment and then it closes. Same thing when I try TF2: Beta. I tried to run it windowed, but that didn't help. Tried with and without Steam beta participation. Tried to re-install them and still no effect.
SS3:BFE, Red Orchestra, Killing Floor, CS 1.6 and Half-Life work just fine.

I'm using Xubuntu 12.10
Core 2 quad q6600 2.4ghz
Radeon HD 7750 with propriate drivers
4gb ram.

Any ideas? :/

Xubuntu 12.10
AMD FX8320
Radeon 6750 (using fglrx-updates source)
8gb ram

Are you sure that you have drivers correctly installed? better to report problems here

sounds like drivers issues.

What is the terminal output? Becuse just saying "blah blah blah doesn't work help." doesn't help find you an answer.

I think your drivers are to old to support your card or they aren't installed correctly.

I had the same effect today and I knew that I didn't have prober drivers because fresh install of kubuntu. I installed 13.1 patched version which I had on my drive and the game started to work. Speaking of CSS source now.
