Well, since reporting this bug I gave up and installed a new Ubuntu 9.10 / GNOME system.
Now about six weeks later, I've got it again, only it seems to be even worse. Other very important things also stop working: Alt+F1 highlights the text "Applications" but the menu does not open. Alt+Tab does nothing. Alt+Space in a window does nothing. The Alt key is ignored in global shortcuts: I've set Ctrl+Alt+T to open a Terminal in the GNOME Keyboard Shortcuts, but from Firefox it just opens a new tab (which should be Ctrl+T). -- Mouse events fail frequently and unpredictably, requiring kwin restart https://bugs.launchpad.net/bugs/505494 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-workspace in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
