Subject: bug#781: Xorg crashes when switching to a console

From: Tom <[email-masked]>
Date: Wed, 30 Aug 2023 16:23:15 -0400

Package: xserver-xorg-core

Version: 2:21.1.7-3devuan1

Observed behavior:

After dist-upgrade from Chimaera to Daedalus, after running x via 
startx, and then at any time switching to a console terminal via 
CTRL-ALT-F# - xorg crashes immediately.

Expected behavior:

When switching to a console terminal xorg should remain running, and it 
should be possible to switch back to it's console.

Attached is a copy of an Xorg.1.log file recorded for a session that 
crashed on vt switch.

Let me know if I can provide additional info, and happy to test if needed.
