Thanks for the log. It shows you're using the old unmaintained intel
driver:
Apr 29 15:25:43 PCBRUANT /usr/lib/gdm3/gdm-x-session[22649]: (II) intel: Driver
for Intel(R) HD Graphics
Apr 29 15:25:43 PCBRUANT /usr/lib/gdm3/gdm-x-session[22649]: (II) intel: Driver
for Intel(R) Iris(TM) Graphics

...
So this is a duplicate of bug 1867668. To fix it just modify your Xorg
config to not load the 'intel' driver and load 'modeset' instead.
Deleting your Xorg config file should also achieve that. And if you can
also remove the package 'xserver-xorg-video-intel' to prevent it from
being accidentally used.
