** Description changed:
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, my system goes to sleep. My
- workaround is to simply open the lid until I see a screen, and close it,
- and then everything returns to normal.
+ 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.
- A excerpt from attached dmest shows wireless ready at 21s and then
+ 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.
