Screensaver not activating, can't enter password on lockscreen.
When I press Ctrl-Alt-L, the screen locks, but the screensaver
doesn't activate. I also cannot enter my password on the lockscreen.
It just shows a blank entry field without a cursor.
I can however click on "unlock", which does nothing because I can't
enter my password, or I can click "switch user", which brings me to
the login screen and then I can login that way.
This is very annoying though, because of the extra step and also because
of the blank screen (screensaver) not working.
I have tried out the latest cinnamon desktop lately, which uninstalled
gnome-screensaver. I reinstalled that after deleting cinnamon though,
but it still doesn't work.
