On fresh ubuntu 8.10 (hd2400 pro agp) after following this guide we get the next present:
This catalyst brother makes me mad!
module ABI major version (0) doesn't match the server's version (1)
Failed to load module "dri" (module requirement mismatch, 0)
Failed to load /usr/lib/xorg/modules/drivers/fglrx_drv.so
Btw, open source driver is good but weak at video playback damn it. All I want is inet, musik and filmzzz in the Saturday evening! Damn, but I spend more and more time in Windblowz, though the "tearing" effect is present there too...
