Bug#961132: light-locker: with the nvidia driver, light-locker suspends the system when locking
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.
