Originally posted by Odur View PostI can restart X-server just fine, and switch VT's. The hard lock only happens when I start another X-session.
I used to get lockup restarting X, but that was fixed a few releases ago.

User switching is what causes Hard Lock Hell for me using fglrx. I haven't tested VT Switching. This is 100% reproducible on a ATI 4670 card & Ubuntu 8.04 LTS (w/latest updates):
1. Log in as a user to default desktop.
2. Switch to a different user using the Fast User Switch agent.
3. Log in as the new user.
* HARD LOCK *
Also, switching users from the screensaver will also lock the system. Sometimes 1 user switch will work, but then trying to switch back to the original user will HARD LOCK the system.
