Recently installed Linux Mint 21 Mate Edition. Then installed Gimp 2.10.30 from their repos.

Gimp has two modes of operation: single and multi-window. Default is single window. A quick operational test in single window mode showed normal operations for everything I tried.

from the Gimp main menu I chose Windows and then uncheck Single-Window checkbox - ie to go to multi-window mode.

I am immediately dumped out of my current user session, I have to log back in.

These lines are in lightdm.log right after tripping session closure. But not sure of where to go from here.

As it turns out an update to a driver for Intel HD graphics has deprecated some older chipsets.

I found a work-around on the Ubuntu Community Forums. The relevant discussion can be found here: https://ubuntu-mate.community/t/browser-consistently-crashes-mate-desktop-session/25855/15 https://ubuntu-mate.community/t/ubuntu-mate-22-04-auto-ending-sessions-when-i-do-something-specific/25897/25 https://wiki.archlinux.org/title/intel_graphics#Tearing

I was attempting to install on an old HP Pavilion laptop that uses an i915 chipset that is no longer supported by this driver.

Work-around involves placing a configuration file named 20-intel.conf into /etc/X11/xorg.conf.d/ containing the following lines:

Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "true" EndSection

This solves the immediate problems I have bee observing.

Thanks to all for your replies. And to all involved in finding and publishing the work-around.
