Thanks for responding so quickly, Peter.<br>
Yes, issuing:<br>
<font face="Courier New, Courier, monospace">$ xinput --disable
'DLL07BE:01 06CB:7A13 Touchpad'</font><br>
<div class="moz-signature">
<div class="moz-signature">
<div class="moz-signature">
<div class="moz-signature">
<div class="moz-signature">
<div class="moz-signature">had the exact same result of
crashing X and killing my user session as `$ xinput
--disable 14`.<br>
<br>
A journald log for today (with only one trace of X
crashing) is at:<br>
<a class="moz-txt-link-freetext" href="https://paste.c-net.org/ApplauseFootball">https://paste.c-net.org/ApplauseFootball</a><br>
(<font face="Courier New, Courier, monospace">$
journalctl -x -o short-full | sed -ne '/Mon
2021-04-12/p' | curl --upload-file -
'<a class="moz-txt-link-freetext" href="http://paste.c-net.org/">http://paste.c-net.org/</a>'</font>)<br>
<br>
I did not apply filters (so journald log entries are all
there), because I just don't know (even after consulting
`$ man 7 systemd.journal-fields`) which ones are
relevant and which aren't.<br>
<br>
Cheers,<br>

[Background info: host OS is Arch linux 5.11.12 with gdm 40.0.1 on xorg]
For the past 4 days, I have this weird mix-up between issuing either of the
following cmds in a `tmux` terminal:
$ /usr/bin/xinput --disable <xID>
or
$ /usr/bin/xinput --enable <xID>
where <xID> is my Touchpad xorg device ID (=14) on a Dell XPS15, obtained
with
$ /usr/bin/xinput --list --short
</pre>

<pre class="moz-quote-pre" wrap="">
First note: you can use the device name, so `xinput disable "my device
name"` - you do not need to use the ID. This has worked for probably a
decade or more now.

<blockquote type="cite">
<pre class="moz-quote-pre" wrap="">Issuing either one of the above cmds instantly kills my gdm user session,
along with all that was going on in it. Next it lands me on the gdm user
login frame, where I can start a new user session as if nothing had
happened. Everything else seems completely normal.

most likely a crash in the X server, please check your journal for any
backtraces and file an issue against the X server (cc @whot, i.e. me) and
we can have a look.
Cheers,
Peter

The touchpad's driver is: xf86-input-synaptics 1.9.1-2 (could not find a
reference to a recent update)
The xorg-xinput version is 1.6.3-2, upgraded from 1.6.3-1 on 2020.05.19 (way
before the issue appeared)
On the other hand, gdm + the linux kernel and headers were upgraded recently
(from /var/log/pacman.log):
- [2021-04-09T08:29:29+0200] [ALPM] upgraded linux (5.11.11.arch1-1 ->
5.11.12.arch1-1)
- [2021-04-09T08:29:30+0200] [ALPM] upgraded gdm (3.38.2.1-1 -> 40.0-1)
I have looked up FAQs, misc FAQs and extra FAQs and all I could on get my
eyes on at xorg, as well as the knowledge base on StackExchange, in addition
to having scanned the web, by I found absolutely no chatter on anything
similar to that issue.
I'm stumped in part because I've used the above cli cmds for years to
activate/deactivate my laptop's touchpad on the fly (on the same box) and
I
never had an issue.
I'm stumped and would be grateful for any pointer.
PS: I have not cross posted on gdm yet. Will do so in a few days only if
needed or recommended by someone deeper than me on the issue.
