I have ubuntu and manjaro installed on my PC and both of them have trouble waking up from suspend. I made the following attempts but no luck:
- rollback kernel from 5.8 to 5.7
- turn off secure boot
Every time I tried to wake my PC from suspend, I can see the fans spinning but the display is not light up. There is no signal to the display. I cannot
ssh to the PC either.
I notice there are some error messages in

What could be the possible cause of this kind of “cannot wake from suspend” problem?
Since my ubuntn install and manjaro install both have the same problem, could it be the graphics driver that causes the problem?
Any possible approaches to fix it?
