[nouveau][conroe] No Gnome is showing up in Ubuntu 20.04 - login to just a blank purple screen

[Frans van Berckel]

Just freshly installed Ubuntu 20.04 on a bare metal Desktop disk partition (for testing purpose only): While booting there is no Gnome showing up. Checking syslog for error's there are these messages ...

Okay, tell me. How do i fire up a graphical terminal on a Desktop without Gnome controls? There is nothing on my screen now. I have access to the computer by ssh, truth.

[Daniel van Vugt (vanvugt)]

Please use SSH or a virtual terminal (Ctrl+Alt+F4).

Thanks. Unfortunately that did not work as well as expected. Please run this command:

  journalctl -b0 > journal.txt

and then attach the file 'journal.txt'.

[Daniel van Vugt (vanvugt)]

Thanks. Curiously that most recent log isn't showing any failure that I can find. It looks like Gnome is working (unlike the log messages at the top of this bug)...

Do you see a login screen at all or does the problem occur before that?

I wonder if the system has just failed switch to the correct VT. Please try Ctrl+Alt+F1 or Ctrl+Alt+F2.

[Daniel van Vugt (vanvugt)]

Also please ensure both your monitors are turned on because the login screen will only appear on one of them.

[Daniel van Vugt (vanvugt)]

When you say "no Gnome showing up", can you describe in more detail what you do see? Maybe with photos?

[Frans van Berckel (fberckel)]

Sorry i wasn't clear about that. I am able to login with gdm3 with user frans as expected. But next i am getting a Desktop without any Gnome controls. I still can move the mouse over two screens. But even clicking on the mouse buttons, doesn't show up any menu, to open up a terminal for example.

[Daniel van Vugt (vanvugt)]

On the login screen please click on the cog wheel icon and check what session type you are using.

Please also attach a photo of the problem.

[Frans van Berckel (fberckel)]

Click on the cog wheel icon, there are three options, Gnome + Remmina Kiosk, Ubuntu and Ubuntu on Wayland. And Ubuntu is selected by default. Next after login, there is nothing on the screen, as in blank / black. Except the mouse pointer.

[Frans van Berckel (fberckel)]

After some time the screen i going to purple, the mouse pointer still there but no change.

[Daniel van Vugt (vanvugt)]

Please attach a photo of what you see after logging in :)
