 2 | Overclock NVIDIA Cards on Ubuntu and Linux based non-mining OS
 3 | 
 4 | If those do not work for your (newer) version of Linux/Drivers, please consider the following:
 5 | 
 6 | If Xorg is not running in root mode try this:
 7 | 
 8 | 1. `sudo vi /etc/gdm3/custom.conf`
 9 | 2. Uncomment the "WaylandEnable" line and make sure it says "WaylandEnable=false"
10 | 3. `sudo vi /etc/X11/Xwrapper.config`
11 | 4. Add "needs_root_rights = yes" to the end of the file
12 | 5. Reboot
13 |
