Hi,
Interesting thing happened to my ATI driver after some upgrading of the system. I have installed the latest ATI driver(Radeon 9700, AMD 64)and next day when I switched on my comp, the old "bug" repeated again. I have no 3D acceleration but only 2D. I opened ATI control panel and there is my card OK,the display driver OK, but Open GL is Mesa. So I installed the driver again and it worked. But next day everything repeated again. Then I opened Yast control center, went to Hardware and open Monitor setup. There was the right monitor and the driver and the 3D check box was checked. I just confirmed that all is OK then the test window opened, confirmed that too and saved the "changes" again. After restarting computer there is ATI driver agan and 3D too. I do not know why this is happening in SuSE 10.1(newer happened in SuSE 10.0).Maybe somebody experienced the same thing and has resolved it.
regards
