Installed on my notebook ASUS X59SL Fedora 13.
Once logged in, 10-15 minutes in the right half of the monitor changes color from blue to green with small ripples. That same thing happened on my Fedora 12 on kernel versions above 220.127.116.11-174.2.22.fc12.i686.PAE. Needless to Fedora 13 work under this kernel. What could be wrong?
