It seems like the (Wayland-based) login screen is failing to start. One reason is the unusual (virtual?) hardware, but the bigger reason is probably just that the 'nomodeset' kernel parameter explicitly prevents Wayland from working.
A secondary problem is that gdm3 should detect the failure and revert to a Xorg-based login screen. That's also not working, but one problem at a time... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1882216 Title: [bochs_drm] Booting gets stuck with corrupt graphics Status in mutter package in Ubuntu: Incomplete Bug description: When booting on a VPS connected via VNC at first the text messages via boot are displayed. Then the resolution changes several times (VNC size changes) and after a lot of resolution changes it gets stuck in a corrupd graphic design. The cursor is still blinking but alt+Fx does also not work. Using sudo service gdm3 stop and sudo startx is working. Due to the fact that the VNC console is completely frozen and this is hosted at a provider I have to use a separate putty session to stop gdm and starting a new gui session which is then displayed in the VNC. This problem does not exist with Ubuntu 18.04 LTS. It does not matter if I use a fresh installed Ubuntu 20.04 or an upgraged 18.04 LTS to 20.04 LTS. On a second VPS the problem is similar but not the same. The second one does not get totally frozen. There is still no GUI when booting but it ends up in a purple uniform screen even the text mode is purple (the first VPS ends up a blueish screen with blue vertical lines). On the second VPS it is possible to switch to shell (purple style) and executing the abovementioned commands directly without a second putty session. But the behavior is basically similar for both VPS. When using sudo reboot the second VPS displays text again and the first only some graphic trash. So basically they have both the same behavior but on the first the graphics are totally destroyed even text is not working anymore. The Funny thing is that startx is still working but after clothng the startx session the graphic trash is shown again.
