The default Ubuntu 18.04 Bionic Beaver installation comes with Wayland enabled. The objective is to disable Wayland and enable Xorg display server instead.

Does not work. After trying to launch Teamviewer GUI it just aborts and nothing ever happens. Maybe I have another problem, cause Teamviewer from Nix sources also does not work.

This caused me the following problem: Bug #1770238 “[nvidia] Logging in results in a black screen for ...” : Bugs : gdm3 package : Ubuntu Screen would go blank after logging in and eventually would get returned to login. Re-enabling wayland fixed it.

Thanks. Seems my system with D525MW motherboard needs this to unfreeze the login screen.

So I did this and rebooted, checked that x11 was running or output said it was running. With GPU in motherboard works just fine with anydesk even on wayland but look n behold I can’t get anydesk to work in headless . I get same error on both wayland and xorg x11 .

“Display server not supported”
Not sure what to do to get anydesk to work headless.

This worked for me. Thank you very much!

I was trying to access a Centos 8 machine from my Windows 10 machine via Teamviewer, but it just showed a black screen. I disabled Wayland in the Centos 8 machine, rebooted, and then it worked.
