Re: login screen scrambled/frozen
Sorry, I thought it might be hard to understand, and I'm having a hard time explaining it. But I think you got the idea, when fc6 boots, and the loading/services screen shows up, it is corrupted and frozen, although I can move the mouse, and I have to reboot. Sometimes after rebooting it works and sometimes it does not, that is the weird part. The one noticeable difference between when it works and doesn't is that when it does work I always see a nvidia logo flash before the loading/services screen where it usually freezes.
Perhaps a picture of the screen might help explain?
I'll try your suggestion and get back.
