[Lenovo ThinkPad T450s] regression: no display when waking from suspend

[Christopher Barrington-Leigh]

I have two Lenovo T450s laptops running Ubuntu 20.10.
A few weeks ago, suspend stopped working properly: with an external monitor, the external monitor no longer registers the connection when waking from suspend.
Without, the laptop screen is black and the machine unresponsive until hard-rebooted, when waking from suspend

Thanks for the bug report. I can see two immediate problems.

The first problem isn't really related to this bug but you should fix it anyway. Your log is being flooded by crashes in 'onedrive'. If you don't need 'onedrive' then consider uninstalling it.

The second problem is these messages in your Xorg logs which might be related to this bug:

[ 87005.338] [dix] EventToCore: Not implemented yet
[ 87131.437] [dix] EventToCore: Not implemented yet
[ 87283.009] [dix] EventToCore: Not implemented yet

Next we would like to see a system log of the problem happening so please:

1. Reproduce the bug again such that the machine is unresponsive.

2. Wait 30 seconds.

3. Do a "hard reboot".

4. Run:

   journalctl -b-1 > prevboot.txt

5. Attach the resulting text file here.

6. Follow these instructions to check for crashes: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

I followed your instructions for prevboot.rxt, though I removed from it a bunch of lines like (no idea what those are)

May 09 06:30:36 T450s-low tracker-miner-f[2128]: Could not enumerate container / directory 'file:///home/meuser/Music/somemusicfolder, Error opening directory '/home/meuser/Music/somemusicfolder/somefile': Permission denied

Also, there's nothing in /var/crash

Also, the most recent listing in the whoopsie page was from January.

Thank you.
