Hi, I am having a problem with Ati driver for Mobility Radeon HD2400 on Slackware 13.1. Driver installs correcly, and when I restart X the mess begins. Parts of screen turn black, parts white, window components are invisible, until I pass with cursor over them. My friend had similar proble, and he just disabled Desktop effects, and everything was fine, but that didn't help me (he has a different Ati graphic card). I was looking for solution for few days, and was unable to find anything that worked. I am new to Linux, and any help would be great!
