Does the same thing happen when you start the "Ubuntu on Xorg" session from GDM? Since you are using a new operating system, it is possible that there is some issue with the installation. I need to eliminate that as a possibility before proceeding to diagnose this as a TurboVNC bug.

Thank you for the fast response. Can you do an idiot walkthrough for me, what you need me to do?

Assuming you have access to the local display on the machine, you should see a login screen. (That screen is provided by GDM, the "GNOME Display Manager.") Click on your user name (or click on "Not listed" and type in your user name.) Then, on the password screen, you'll see a gear icon in the lower right. Click on the gear icon and select "Ubuntu on Xorg" before entering your password. Once you log in, verify whether the browser and other applications are still missing.

I was not at the machine, there is no "Ubunto on Xorg" option. The two options are

  • "Ubuntu" (default)
  • "Ubuntu with Wayland"

On the local desktop both give me the normal view with the browser and favorite applications.

I assume something is not configures like it should for TurboVNC?

Some more infos not sure how relevant:

  • Xorg is installed, and when I use nvidia-smi it always shows it running
  • disabling wayland with enableWayland=False in the gdm3 custom.conf; only removed the with wayland option but changed nothing with TurboVNC

That's weird. My Ubuntu 22.04 installation shows two Ubuntu session options, "Ubuntu" and "Ubuntu on Xorg", when Wayland is enabled in GDM (which is the default.) I wonder if whatever is causing that difference is also causing the issue you observe with TurboVNC. (To be clear, I cannot reproduce that issue on my system, and I just ran apt upgrade to install the latest Ubuntu 22.04 updates and still can't reproduce the issue.)

Whether or not Wayland is enabled in GDM or Xorg is installed/using the GPU doesn't matter for TurboVNC, since TurboVNC is an independent virtual X server. It only mattered for the purpose of testing whether the issue was reproducible on the local display.

Can you do the following and post the output?

$ ls -l /usr/share/xsessions/ubuntu*
$ for file in /usr/share/xsessions/ubuntu*; do echo "*** $file"; cat $file; done

Also please post the output of env from a GNOME terminal inside the TurboVNC session and the same from a GNOME terminal inside the local Ubuntu/Xorg session. You can e-mail me the files if you don't want to post them here.

Can you re-post the local environment variables from an Xorg session instead of a Wayland session? Thanks.

I assume the display changed to 2 because I logged in via TurboVNC before login in after reboot.
Ubuntu and "Ubuntu with Wayland" are still the only options in the login screen.

A apt upgrade was also done; not fixing the problem.

I'll compare these to the results from my system when I get a chance, but at the moment I don't see any obvious explanation for the issue.
