When I launch TF2 through steam all i see is a black screen. I am running 12.04 on an IBM thinkpad T42.
I have already tried adding
export LANG=C export LC_NUMERIC=POSIX export force_s3tc_enable=true
I am in windowed mode, I had the same problems when I was in full-screen. Here are the start up options I had on TF2
-window -dxlevel 85 -console -nojoy
output of lspci, this is the the full output just the output about graphics card
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV200 [Mobility Radeon 7500]
When I go to Dash ---> Details it says my graphics are
R100 (RV200 4C57) x86/MMX/SSE2 TCL DRI2
Here is a question about installing drivers for my graphics card. How do I install the drivers for my Mobility Radeon ATI card?
