Package: light-locker Version: 1.8.0-3 Severity: important With the nvidia driver, light-locker suspends the system when locking. In the journalctl logs, I get a line like
May 20 09:16:43 zira systemd-logind[785]: Suspending... and according to the systemd maintainer, this is light-locker's fault. This happens at lock time, thus immediately with --no-late-locking, and at the time of screensaver deactivation with --late-locking. Note: Until yesterday, IIRC, using --no-late-locking (at least) did not trigger a suspend, but the screen was unblanked after a few seconds (it remained black, but the DPMS state was no longer off, which defeats the purpose of the screensaver nowadays). So this may be related to some conditions. Moreover, after the resume, this puts the system in a bad state, and the X server (thus lightdm) no longer works (apparently, according to the lightdm Xorg logs, no screens found). I can switch to a VT, but the login prompt is shown only for a fraction of second, after which I just get a blinking cursor over a black screen. In case this matters, my xrandr configuration is xrandr --output DP-3 --off \ --output DP-4 --auto --primary \ --output DP-5 --auto --right-of DP-4 where DP-3 corresponds to the laptop screen. But this is no longer honored after the resume. -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.6.0-1-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=POSIX, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE=POSIX (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages light-locker depends on: ii dconf-gsettings-backend [gsettings-backend] 0.36.0-1 ii libc6 2.30-8 ii libcairo2 1.16.0-4 ii libdbus-1-3 1.12.16-2 ii libdbus-glib-1-2 0.110-5 ii libglib2.0-0 2.64.2-1 ii libgtk-3-0 3.24.20-1 ii libpango-1.0-0 1.44.7-4 ii libpangocairo-1.0-0 1.44.7-4 ii libsystemd0 245.5-2 ii libx11-6 2:1.6.9-2+b1 ii libxext6 2:1.3.3-1+b2 ii libxss1 1:1.2.3-1 ii lightdm 1.26.0-7 light-locker recommends no packages. light-locker suggests no packages. -- no debconf information -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
