This appears to be a duplicate of bug 1733292 so please use that one
from now on.
Separately, I notice you seem to be using the *old* 'intel' graphics
driver (according to XorgLog.txt). If you can find the Xorg config file
(maybe in /usr/share/X11/xorg.conf.d) that is loading the 'intel'
graphics driver then I recommend removing that. The latest driver is
called 'modesetting' which should be used instead of 'intel'. And it
will be used automatically if you remove the config file that was
loading 'intel'.

Title:
Xorg crashes sometimes with Easystrokes
Status in xorg-server package in Ubuntu:
New
Bug description:
Xorg crashes, session closes, all unsaved data is gone.
What I did / Reproducing
===========================
It happens when I use Easystrokes to emulate `Ctrl+F4` or
`Ctrl+PageUp/Down`.
So far it happened about 5 recognized times, 3 recorded within the
last 3(?) month. twice during tab switching in incognito Firefox and
once in VSCode.
Reproducability
================
I feel it's very consistent in crashing in Firefox incognito. But it's not
purposely reproducible 100%.
I would give more information, but the stacktrace of the crashdump
does not tell much. I installed debug symbols for xorg, but they made
no change viewing it.
Here is the (obscured) stack trace:
