Package: kwin-x11 Version: 4:5.8.2-1+b1 Severity: normal Dear Maintainer, sometimes kwin_x11 hangs and can only be killed (SIGKILL, not SIGTERM) via a console. Afterwards compositing is disabled. This happens quite regularily with the current versions and the nvidia driver (375.26-2), which probably should be fixed in the freeze before the stable release. The steps to restart it without killing the session are quite a bit of work: - switch to linux console - killall -9 kwin kwin_x11;sleep 3;DISPLAY=:0 kwin & exit - switch to the X-Server again - Sometimes you need to kill kwin again (focus on windows works again now) and restart it - Use systemsettings to re-enable compositing - Use kwin --replace to get a working instance again
I am not sure what is causing the problems, but it happens too often as i would recommend including it in this version into a stable release. -- System Information: Debian Release: 9.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages kwin-x11 depends on: ii kwin-common 4:5.8.2-1+b1 ii libc6 2.24-9 ii libepoxy0 1.3.1-2 ii libgcc1 1:6.3.0-5 ii libkf5configcore5 5.28.0-1 ii libkf5coreaddons5 5.28.0-1 ii libkf5crash5 5.28.0-1 ii libkf5i18n5 5.28.0-1 ii libkf5windowsystem5 5.28.0-1 ii libkwinglutils9 4:5.8.2-1+b1 ii libkwinxrenderutils9 4:5.8.2-1+b1 ii libqt5core5a 5.7.1+dfsg-3+b1 ii libqt5gui5 5.7.1+dfsg-3+b1 ii libqt5widgets5 5.7.1+dfsg-3+b1 ii libqt5x11extras5 5.7.1~20161021-2 ii libstdc++6 6.3.0-5 ii libx11-6 2:1.6.4-3 ii libxcb-cursor0 0.1.1-3 ii libxcb-randr0 1.12-1 ii libxcb-xfixes0 1.12-1 ii libxcb1 1.12-1 ii libxi6 2:1.7.9-1 kwin-x11 recommends no packages. kwin-x11 suggests no packages. -- no debconf information
