After trying to fix my graphics drivers I have finally come to a point where I get a black screen on boot, even though "nomodeset" is set in /etc/default/grub.
The system is a Thinkpad X1 carbon with an Intel HD 620 graphics card.
The full previous story is here, but to be short the thing is that Ubuntu was no longer loading the intel drivers but the system would boot and see fine but with some issues (brightness controls broken, not suspend on closing lid), and in my attempt to fix things I did this:
sudo add-apt repository -y ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade
After that I would see this:
Then I tried to force the intel drivers doing:
sudo apt install xserver-xorg-core-hwe-18.04
sudo apt install xserver-xorg-video-intel-hwe-18.04
After this, I get a black screen on boot. I tried to undo it by
sudo apt-get remove xserver-xorg-core-hwe-18.04
sudo apt-get remove xserver-xorg-video-intel-hwe-18.04
But I still get the black screen (again, I have "nomodeset" in the grub file).
Some help for fixing this enormous mess would be greatly appreciated!
EDIT: It keeps getting better. Now I saw that all the xserver-xorg-video-* packages are gone, by doing dpkg --get-selections | grep xserver-xorg-video I only see xserver-xorg-video-intel and xserver-xorg-video-intel-hwe-18.04, both marked as rc.
EDIT2: Well, I managed to fix the black screen by doing
sudo apt-get install --reinstall xserver-xorg
However, still I get the 'llvmpipe' as the graphics in the Details window...
EDIT3:
IT IS FINALLY FIXED!!!!
After the last edit, I removed the 'nomodeset' from the GRUB file and it is finally working!
All the apparent issues are gone (brightness and suspend working again),
lshw -C video shows configuration: driver=i915 and in the Settings window I see "Mesa Intel HD Graphics 620 (KBL GT2)"
