====== XFCE ======

===== Black screen with mouse cursor after resume from lock =====

X server works correctly. Mouse cursor is working. It is possible to switch to greeter
and login as another user to get GUI working as another user.

<code bash># dm-tool switch-to-greeter</code>

Another options to try: ''xscreensaver-command -d or loginctl unlock-sessions''

Possible cause:
  * light-locker: remove and use xfce4-screensaver
  * nvidia driver
  * multiple monitors + NVIDIA
  * LUKS
    * ''systemctl start nvidia-persistenced.service'' asks for password for unlocking LUKS (which is already unlocked!)

    The solution for me was to delete ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml
