### Tips

### Fix Blank Screen for Ubuntu Workstations (Ubuntu 16+)
Ubuntu uses the wayland display manager instead of the regular x11 server. This causes MeshCentral to show a blank screen when trying to access the remote desktop feature. You can't login, view or control the client. There is a neat fix for this, so don't worry:
```
sudo sed -i '/WaylandEnable/s/^#//g' /etc/gdm3/custom.conf
sudo systemctl restart gdm
```
This will cause your screen to go blank for a second. You will be able to use remote desktop afterwards.
> If you get an error like "file not found", you are probably still using Ubuntu 19 or below. On these machines, the config file will be located on /etc/gdm/custom.conf. Modify the command above accordingly. <
Please note that remote desktop features are only installed when you used the workstation agent. You may need to reinstall your mesh agent.

### WARNING

- Running uninstall will **not** remove the connections from the TacticalRMM and MeshCentral Dashboard. You will need to manually remove them. It only forcefully removes the agents from your linux box.
