Graphics display problem on cold boot
Whenever I cold boot my PC, sometimes everything is fine, but mostly the graphical login screen does not appear, and screen remains grey, stuck at the point before the appearance of mouse cursor. If this happens I cant even switch to other TTY with Alt+F1 or Fn. Sometimes login screen appears but display keeps flickering and moving all over the screen, with everything distorted. In this case I can swith to text console. But if i restart x-server with Alt+Ctl+Backspace, the problem persists without change or is worse (becomes like the first case).
On a reboot or two the problem goes away and everything is normal.
What could be the problem?
I am on Debian lenny with KDE3.5 desktop.
