Thanks for the bug report.
It appears you're using the old unsupported (and buggy) 'intel' graphics
driver. Please remove any config files you have loading that and even
consider removing the entire driver:
sudo apt remove xserver-xorg-video-intel
Alternatively, please just log into 'Ubuntu' t
yeah, I added config to xorg.conf which contains this:
Section "Device"
Identifier "Card0"
Driver "intel"
BusID "PCI:0:2:0"
Option "DRI" "3"
Option "TearFree" "true"
EndSection
I have no deep understanding about how to switch drivers or how to use another
one(which one?),
but without this config
That config section you mention needs to be removed entirely because the
"intel" driver is buggy, unsupported and was only designed to handle
much older Intel GPUs.
Sadly that does mean you lose the "TearFree" option. It has been
requested in the new driver for some time
(https://gitlab.freedeskto
Just, one more question,
I removed config, and removed xserver-xorg-video-intel driver
but I do not know if it took any effect.
How do I find out what driver was used before, and what is used now?
lshw -c video shows:
driver=i915
is it that obsolete driver?

You received this bug notificatio
On Linux you have two or three graphics drivers all working at the same
time at different levels:
* Kernel: i915
* Mesa: iris
* Xorg: modeset (replaces the old "intel" driver)
To confirm which Xorg driver is in use you can find it in the Xorg
system log messages:
journalctl -b0 /usr/bin/Xor
