I'm using FC2 with the latest fglrx driver for radeon cards. Everything gets detected okay, but when I try to run GL apps like glxgears it runs for about 20 seconds then X locks up. 2D seems to work fine. fgl_glxgears gives me frame rates of around 230-280 fps. glxgears reports 1100+ fps. glxinfo reports DRI is enabled. I followed all the directions in the forums but still I have the same problem. Could someone lead me in the right direction. I desperately want to get my winex and Neverwinter Nights (linux client) back up and running.
