    VT switching works just fine. Restarting the X server is what locks up the machine. (Press CTRL+ALT+Backspace in X. Viola, bye bye system. Needs hard reset.)
    I can restart X-server just fine, and switch VT's. The hard lock only happens when I start another X-session.

      Same here. Restarting X is fine. Starting a second X session causes total machine lockup.
      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.

          For me, even restarting the X server results in a backtrace and the system will eventually lock up.

            Bridgeman,

            Any update on investigating this?

              This is 100% reproducible on a ATI HD 3850 (agp) & opensuse 11.1 (w/latest updates)

                Just want to mention that this problem is reproducible with both Catalyst (fglrx) 8.12 and the new 9.1! I am running 64-bit Ubuntu 8.04LTS if that helps... My multi-user linux is effectively a single user system with fglrx.

                  Same symptoms on OpenSUSE 11.1 with HD3650 card, even just logging out of X will cause a hard lock.

                    Same sysmptoms on OpenSuSE 11.0 with HD3450 card. No problems on logging out, but immediate freeze when trying to start a second X-Session.

                    Interesting thing: when I used the built in HD3200 from the 780 Chipset this did not occur.
