nVidia RTX 2080 driver issue with remote desktop (VNC, NX, etc.)

Ask Ubuntu Asked on November 23, 2021

Description: The screen (especially terminal programs such as Terminal and Terminator) do not refresh properly when using any kind of remote desktop. There is occasionally quite a long lag, for example, when typing into a terminal window. If I switch to nouveau driver the issue goes away completely. The issue appears with both nVidia 430 and 440 versions. Old drivers don’t support RTX 20 cards so I can’t for example try 390.

I tried different remote desktop servers such as the NX NoMachine, and VNC vine, as well as different clients on MacOS and Windows, I even tried TeamViewer, all behave the same.

I have reinstalled Ubuntu 18.04 and no change.

Both the server and client are connected to wired gigabit router.

One Answer

The issue is there since like two years. Not addressed by nVidia.

I see it with Ubuntu 18.04 and GeForce GTX 750 Ti, using X11VNC to connect.

Enabling seconds in GNOME clock makes the screen refresh at least once a second, which helps if you need a fast workaround:

gsettings set org.gnome.desktop.interface clock-show-seconds true
