I have lost the ability to kill the X server from the login window (slick-greeter)
[I reported this on the Github/Lightdm but no replies yet]
I used to have Lightdm v. 1.26 on Debian Bookworm. I was able to kill
and restart the X server by doing the canonical CTRL-ALT-backspace from
within the login window in Lightdm (slick-greeter). I need to to this
every now and again to refresh the X server without logging in first.
Now I have upgraded the system to Debian Trixie and I have lost this
functionality, although I can still use the above mentioned key
combination once logged in, or alternatively by switching onto the
console, and type "pkill Xorg", but this is an extra complication.
I have completely purged lightdm* + slick-greeter, reinstalled them and
rebooted but the problem persists.
Has this functionality been removed or has anything gone wrong during
the update?
There are some minor changes between the old configuration file and the new.
Debug info:
$ lightdm -v
lightdm 1.32.0
$ lightdm --show-config
