Can confirm 5.9.0-rc1 did not work for me (following the instruction at
https://wiki.ubuntu.com/Kernel/MainlineBuilds). I also experienced the

Public bug reported:
Upon clicking suspend via Log Out... button in Xubuntu and also via
systemctl suspend, the screen turns to black for 2 sec but then brings
me back to log in screen instead of suspending.
This was not an issue in 18.04. Currently on fresh install of 20.04.1.
