In order to use vesafb instead of radeonfb, I added kernel boot parameter vga=0x301, and this problem was gone. I also found that Matrox G450 which uses matroxfb shows same problem, and workarounded with vga=0x301 too. > New udev-071-0.FC4.1 breaks gdm login screen for PC with ATI Radeon. > Many white and black vertical lines displayed whole screen. > When I switch console to 1 and back to 7, login screen is displayed fine. > It seems related to framebuffer console? > > I have two Radeon PC, one is laptop which has Radeon Mobility U1, > another box has Radeon 7000/VE AGP card. > Both of them shows same problem. > The kernel-2.6.14-1.1656_FC4 and new udev show this problem too. > Rawhide or FC5T2 do not show this problem. -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
