If those do not work for your (newer) version of Linux/Drivers, please consider the following:
If Xorg is not running in root mode try this:
sudo vi /etc/gdm3/custom.conf- Uncomment the "WaylandEnable" line and make sure it says "WaylandEnable=false"
sudo vi /etc/X11/Xwrapper.config- Add "needs_root_rights = yes" to the end of the file
- Reboot
