I'm having the same problem. Kubuntu 10.10 (AMD64), fully updated. Graphics is Radeon HD 3200 with opensource drivers (MSi Wind12 U230). Kwin crashes X when effects are turned on. I found out later that Kwin doesn't crash (as much) when I turn off the blur effect. When testing when blur effect is turned on, opening internet browsers tend to accelerate crashing. With blur effect off, compositing seems to work relatively well (with a slight performance hit, especially when a terminal with transparency is rendering on the screen).
Running "kwin --replace" in a terminal shows (don't know if this is useful or not): kwin(2307) KWin::CompositingPrefs::detectDriverAndVersion: GL vendor is "Advanced Micro Devices, Inc." kwin(2307) KWin::CompositingPrefs::detectDriverAndVersion: GL renderer is "Mesa DRI R600 (RS780 9612) 20090101 TCL DRI2" kwin(2307) KWin::CompositingPrefs::detectDriverAndVersion: GL version is "2.1 Mesa 7.9-devel" kwin(2307) KWin::CompositingPrefs::detectDriverAndVersion: Detected driver "radeon" , version "20090101" QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No such file or directory QFileSystemWatcher: failed to add paths: /home/chris/.config/ibus/bus Bus::open: Can not get ibus-daemon's address. IBusInputContext::createInputContext: no connection to ibus-daemon kwin(2307): OpenGL compositing self-check failed, disabling compositing. However, opening the effects settings, turning off blur effect, and resuming effects will still allow transparency. Also noticed that when effects are turned off, I also get a lot of flickering graphics. When effects are turned on, the flickering is reduced (if not completely gone). Also noted that when Kwin does crash, it tends to make all the effects in the effects settings disappear, and the window decoration resets back to the default oxygen window decoration. At the same time, I run Kubuntu 10.10 (AMD64) on my desktop which has a Intel Core Duo 3.16GHz processor, GeForce 9800GT, and kwin runs perfectly with all effects. -- KWin+Radeon+Latest Kernel AMD64 Constantly Crash https://bugs.launchpad.net/bugs/663660 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
