I too got this bug and haven't found a solution yet. Dist: Kubuntu 8.04.1 Fully upgraded Graphics card: PowerColor (ATI) HD3870 SCS3 Tested drivers: fglrx 8.3 through 8.9
Symptoms: When switching user the screen goes black and the system is totally unresponsive, including the keyboard. Not even caps-lock trigges the caps-lock light. The only thing that works is the reset button and to hold the powerbutton until it shuts down. Shutdown or restart works without problem (I have fixed the problem with atieventsd, see bug 118605). If i use the vesa or radeonhd drivers everything is ok. But then I got no 3D acceleration, which I think would be nice... This bug is really annoying to me, as we are switching users a lot on this computer. It started when I bought this card. I got a ATI X600 before, and that didn't suffer from this bug at all. Anything else I could provide to help solving this bug, or at least get it triaged? -- Switch User freezes at blank screen https://bugs.launchpad.net/bugs/112518 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
