I am using radeonfb. After bootup, the screen sometimes looks like it is melting. I made a video to show you what is going on: http://bu3sch.de/misc/after_boot.avi (6.1 MB) It does only happen sometimes. I could not find a way to reproduce it. If I start X after boot with a melting screen, X is also melting: http://bu3sch.de/misc/after_x_switch.avi (6.6 MB) But here comes the interresting part: If I switch back into the console, the screen becomes normal again and I can continue to work as usual. I am suspecting some initialization routine bug. It never happened when booting into OSX. In X I use the "radeon" driver. Please give some suggestions on how to track down the problem. PS: I am very sorry for the big video files. I tried to install some video coding software to reduce the size, but it appears that installing video software on linux is a nontrivial task. I stopped after resolving the millionth dependency manually. :) -- Greetings Michael.
