Description
Qubes OS version
4.0.4
Affected component(s) or functionality
Screensaver, locking with Ctrl-Alt-L
Brief summary
Nothing happens when trying to lock the screen. No logs. Screensaver IS set to autostart already. And it works for some time. But after some time, (not sure about the exact cause), inactivity timer does not lock the screen, nor the screen lock shortcut works. When I open the Xfce Screensaver panel, it complains about the screensaver daemon being not running. Even after starting the daemon, same thing happens after some time.
As there is no log at all, I cannot trace the cause.
How Reproducible
This started a few days ago, probably after applying a UEFI firmware update. The bug is always present since then, I guess.
To Reproduce
Steps to reproduce the behavior:
- boot the system
- log in. do some work.
- the computer won't lock when you expect it to lock its screen
Expected behavior
The lock should work.
Actual behavior
Lock is disabled
Screenshots
Additional context
It might be considered a security issue as well, I did not notice that the screen was not locked but had the impression that it was.
Solutions you've tried
starting the xscreensaver using the respective xfce settings panel
Relevant documentation you've consulted
Found some basic info that suggests to restart the screensaver, to put it into autostart (which already appears in session and startup panel as a ticked item)
