Hi! I just moved back to xmonad after having used qtile for a few years and I'm having trouble locking my screen using light-locker-command. When calling "light-locker-command -l" from the command line, I get the this back: "Received error message from the locker: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files" I'm running Ubuntu's mini.iso, lightdm, and a simple session file that just calls /etc/X11/Xsession. My .xsession only adds "~/.cabal/bin" to the PATH and execs xmonad. xmonad version is 0.15 but I get the same behaviour when installing xmonad via apt and running the package's session. I have tried purging and reinstalling both lightdm and light-locker. The curious thing is that the same lock command works fine if I run qtile from my .xsession instead of xmonad. Any pointers would be greatly appreciated! Thanks! Thomas
