Laptop with USB-C external monitors sleeping shortly after login

[iMac]

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.

 root@imac-XPS-13-9365:~# systemctl status sleep.target

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.

 Dec 10 09:00:08 imac-XPS-13-9365 upowerd[1399]: treating change event as add on /sys/devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1:1.1/0003:046D:C534.0004/0003:046D:4023.0006/power_supply/hidpp_battery_0

Still later we have

gdm detects my panel, even though the lid is closed

Then we get to here

 Dec 10 09:00:13 imac-XPS-13-9365 systemd[2829]: Reached target GNOME Session (session: ubuntu).
..
And then all of a sudden the network manager is announcing sleep has been requested

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

And here is the dmesg

Here is some additional info

attached cleaner output of systemd-inhibit

And here I attached what systemd-inhibit looks like just after I login, but before my computer is put to sleep

This sounds close enough to bug 1841826 that we should use that for now.
