nvidia legacy blob, try (just a wild guess) export KWIN_EXPLICIT_SYNC=0 kwin_x11 --replace & And please attach the output of "qdbus org.kde.KWin /KWin supportInformation" (with compositing enabled) in any case. The crash itself is deep in the driver. Thanks for the prompt response. Yes, setting the environment variable and restarting kwin_x11 as described above does work around the problem. I should add for the documentation of this issue that my graphics card is a GeForce 7300 LE and the specific driver is am using is the xorg-x11-drv-nvidia-304xx-304.125-1.fc22.x86_64 package from rpmfusion. The output from qdbus after the restart is: $ qdbus org.kde.KWin /KWin supportInformation KWin Support Information: The following information should be used when requesting support on e.g. http://forum.kde.org. It provides information about the currently running instance, which options are used, what OpenGL driver and which effects are running. Please post the information provided underneath this introductory text to a paste bin service like http://paste.kde.org instead of pasting into support threads. ========================== Version ======= KWin version: 5.3.1 Qt Version: 5.4.2 Qt compile version: 5.4.1 XCB compile version: 1.11 Operation Mode: X11 only Build Options ============= KWIN_BUILD_DECORATIONS: yes KWIN_BUILD_TABBOX: yes KWIN_BUILD_ACTIVITIES: yes HAVE_WAYLAND: yes HAVE_WAYLAND_EGL: yes HAVE_WAYLAND_CURSOR: yes HAVE_XKB: yes HAVE_INPUT: yes HAVE_XCB_CURSOR: yes HAVE_XCB_SYNC: yes HAVE_X11_XCB: yes X11 === Vendor: Fedora Project Vendor Release: 11701000 Protocol Version/Revision: 11/0 SHAPE: yes;

Before, I would have the crashing and automatic restarting happen several times in the first few minutes after starting KDE. Now the system seems much more stable. After several hours of use, I have not seen the crash and restart message at all. However, Google Chrome has frozen a couple of times, but when I run:
kwin_x11 --replace &
in a KDE Run Command... window, Chrome unfreezes and the system is fine.
Thanks for your help. I hope the driver is fixed before long.
Chromium issue is very likely #342326 - it should be sufficient to restart the compositor (SHIFT+Alt+F12 twice) to resume it. |
