I'm running Ubuntu 20.04 on an Acer Thinkpad A475. Suspend and shutdown have stopped working properly. When I suspend, the laptop won't wake, forcing me to hold the power button until it turns off, then start it up again. When I try to shutdown or restart, the same problem happens. The screen goes black, but the power button remains lit and I have to hold the power button to make the laptop turn off.


I've been googling this problem for several days. One suggestion to diagnose the problem was to power down the laptop, wait a half hour, then forcefully power down by holding the power button, then after restarting, run sudo journalctl -b -1 -e. This is the result:

I've tried looking for missing drivers, with ubuntu-drivers devices, but the result is blank. I've seen that this could be also be a GPU or kernel issue. Any help you can provide in finding a solution would be greatly appreciated.


UPDATE
Shutdown and Restart both work when booted into recovery mode, and suspend is closer to working. When booting into recovery mode I get a warning saying "some graphic drivers require a full graphical boot and so will fail when resuming from recover", so maybe this is a graphics driver problem? I've made sure my graphics driver is up to date. My graphics card is an AMD Radeon R7 Graphics and the driver is AMD GPU.

I was able to fix this (after trying lots of different fixes and progressively making this worse) by getting a fresh install of Ubuntu 20.04 LTS and choosing to use kernel 5.11.0-27-generic (which came with the install) instead of the newer 5.11.0-43-generic that is the default at the time of writing. So maybe it was a kernel problem all along and I just needed to try an older version (I only tried as old as 5.11.0-38), or maybe there was some other lingering issue as well that the fresh install wiped out.
