Re: Cannot lock screen in lxqt desktop

Hello again.


Did you install xscreensaver on your user Guix profile too? If not try it. Also try invoking xdg-screensaver from a terminal, it may print more useful info about why it's failing to run the screenlocker program, like which locker exactly is trying to run.

As I understood xdg-utils is installed along the lxqt desktop, but I wonder why the "Lock screen" button is not working therefore. Installing xautolock in my home profile did also not resolve my problem.
