Description: Ubuntu 20.04 LTS
Release: 20.04
I recently upgraded from 18.04 to 20.04 and was using MATE. When the upgrade was run my external
HDMI monitor was plugged in, after the update, when I reboot, the internal monitor shows the beginning of the boot process (I deactivated 'silent splash' by editing grub.cfg) then it switches to the HDMI monitor and the internal monitor goes dark. I can also get the tty consoles on the external monitor but not the external monitor.
In MATE it was a real problem because the panel is apparently still on the invisible part of the desktop; I used a tty to install gnome, then I could get the display settings by right-clicking on the desktop, and setting the monitors to mirror, so I can reach applications, etc.
Computer is a Dell Inspiron 3275 AIO with touch screen and Intel on-board video, I think.
I had no problems with Ubuntu 18.04 with MATE.
The problem seems to be similar to this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874194
but sort of the reverse, in that the internal monitor is the problem.
Thank you for your help.
