<pre>My machine does suspend/resume on lid close/open only if on battery, which
isn’t the case for all my tests here. So all I describe is when plugged on AC,
and there isn’t anything suspend related here. ;)
On lid close, the screen goes black, which is expected. Then, on lid open, it
stays black until I hit a key or move mouse, which is the issue I’m reporting.
And for the second point (with PSR enabled), it’s exactly that you described.
After hitting a key or moving the mouse a first time, the screen isn’t black
anymore, but « contains a stale image back from when I last entered my password
in the login screen », which also disappear when hitting a key or moving the
mouse. Sorry if I wasn’t very clear in my previous message, english isn’t my
mother tongue at all.
To be a bit more exhaustive, I’ve tried on battery. Lid close, screen goes
black and computer suspend. Lid open, nothing happens (which might be an issue
in fact, but probably for a different report — I expect my computer to resume
on lid open). Power button: resumes directly to the lock screen, without any
black screen or stale image.
In dmesg, I have this on lid close:

Then suspend/resume stuff, but the second part (from other messages here) isn’t
present, which I kind of expect since no black screen. However, any further lid
close (whether on battery or AC) leads to the same first part as other second
attempts:
[ 6880.004203] pci_bus 0000:04: Allocating resources
[ 6880.004231] pci_bus 0000:06: Allocating resources
[ 6880.004262] pci_bus 0000:07: Allocating resources
[ 6880.075329] pci_bus 0000:02: Allocating resources
And when on AC (nothing on battery), on lid open:
[ 6881.087919] pci_bus 0000:04: Allocating resources
[ 6881.087955] pci_bus 0000:06: Allocating resources
[ 6881.087992] pci_bus 0000:07: Allocating resources
[ 6881.159286] pci_bus 0000:02: Allocating resources
I suspect that if it was resuming on lid open, the black screen issue could be
present too.</pre>
