Public bug reported:
Hello,
I have a certified Dell XPS 13 9370 that had Ubuntu pre-installed,
though I have since installed normal 20.04 on it. I have my mouse,
keyboard and headset dongle plugged in via my USB-C monitor. This works
well.
Every evening, I suspend to RAM (note that I changed this from the
default instant suspend thing to proper suspend to RAM, as it was
draining battery terribly Bug #1808957 )
$ sudo cat /sys/power/mem_sleep
[s2idle] deep
When I resume from sleep in the morning, the USB mouse, keyboard and
headset dongle nearly never (but do occasionally) work. The lights on
the dongle and mouse are not turned on.
It is really annoying, as it means I have to keep re-suspending or
pulling the cables out and in again until it finally starts working
again or I shut everything down and restart.
Any help would be appreciated. Please let me know if any further
information would be helpful
