Public bug reported: I use Kubuntu 9.04 beta on an AMD64. lspci shows me the following line for my graphics hardware:
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon XPRESS 200M 5955 (PCIE) There is no explicit video driver setting in /etc/X11/xorg.conf. I think, radeon is used. When desktop effects are enabled, the system often freezes, typically when windows are opened. I can trigger these freezes quite reliably by starting Quassel and opening the settings dialog. The system doesnât respond to any keys anymore, not even to Ctrl + Alt + F1 (console switch). However, the mouse pointer can still be moved. If I enable XAA in /etc/X11/xorg.conf, the system not only freezes but the screen gets completely black. If you need further information, please ask. ** Affects: ubuntu Importance: Undecided Status: New -- Kubuntu freezes when desktop effects are enabled https://bugs.launchpad.net/bugs/351990 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
