http://forums.opensuse.org – I installed OpenSUSE 11.1 and everyhting was going well for about a week, and then the last time I rebooted it I got Penguins walking around a snowey environment while the boot menu was asking me if I wasted to load in failsafe mode or regular...? Anyone know anything about this...? The screen has gone back to the regular grren theme now but I don't want it to do this anymore. (Distributions)
