Public bug reported:
Since upgrading to Ubuntu 20.10 on my Dell XPS 9380, I now experience an
unwanted sleep immediately after login. It seems to only occur when I
am at my office, where I use dual 1440p displays connected via USB-C,
and close my laptop lid immediately after power-on.
Previously, the system would boot and use my external displays without
issue. Now very shortly after I login (enough time to launch a terminal
a cat my syslog), my system goes into a sleep state. My workaround is
to simply open the lid until I see the laptop panel light up, and
immediately close it, and then everything returns to normal on my
external displays right back where I left it.
An excerpt from attached dmesg shows wireless ready at 21s and then
deauthenticating at 34s after I login.

Output from systemctl confirms my wakeup from a sleep state using my
open-lid method described above. For anyone else on a 9380, it is worth
noting my hostname identifies an older 9365 XPS model I had previously.

I assume it must be something to do with gdm not detecting external
monitors after login, however I do not close the lid, so I am still not
sure why a sleep state is triggered. Current packages listed below.

I have included my syslog as well, where you can align the dmesg of my
wifi coming on, and then turning off with the following entries.

In between these in my syslog I browsed for lines that might indicate
something triggering sleep, and below are some lines I thought were of
interest (complete syslog for the period attached).
Everything seems fine up to here ..

This one is interesting, maybe just re-detecting my power supply (which
was already plugged in) or an indication that it reach 100%, since it
was likely nearly fully charged.

Still later we have

So I really have no idea what might be causing this, and it doesn't seem
clear from what I have reviewed so far.
