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.
