I can confirm this behaviour, system locks up or screen goes completely dark with a hard reset as the only option left. This is on a Laptop with an Ati Radeon 9600 Mobility M10 (RV350) card using the radeon driver and kwin's compositing effects enabled.
The lock-ups occur when opening random applications, so far it happened to me while opening kwallet, login-manager, kate, kpackagekit and others. Also, X sometimes uses up to 50% of the cpu-time. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
