When I Ctrl-Alt-F1 to get to a terminal, or start a second session in KDE, the screen fills with random corruption and the computer is unresponsive and needs a hard reset. Logging out of my current session seems to work OK - presumably because I just get taken back to KDM within the same VT. Reproducible: Always Steps to Reproduce: 1. Allow computer to boot as normal 2. Wait for X to start 3. Ctrl-Alt-F1 or Switch User Actual Results: Immediately, the screen goes to what appears to be the resolution it booted at, but filled with randomness rather than the terminal one would expect. Nothing can bring the system back: a hard reset is the only option The Tuz graphic that ought to appear during bootup is also replaced by a square of random corruption. Boot messages appear as normal, though.
What was the last kernel you used that worked? Also, please post 'lspci -v' output for hardware info
I only just noticed the viafb driver in the list, I'd been using vesafb before. 2.6.29-r5 is the only kernel I tried viafb with. Here's lspci: 00:00.0 Host bridge: VIA Technologies, Inc.
