Black screen with underscore after long suspend

Hello everyone, I recently swapped from KDE Neon to Manjaro on my HP laptop.
I’m really enjoying it so far, but I have this annoying issue, and I’d like to solve it.

Sometimes, when after long suspensions, I have nothing on the screen but a black screen with a non-blinking underscore. I cannot switch to any tty, when I try to do, so I can see the underscore blink for a moment like if something really happened and if I try to go back to the desktop I just get a black screen.

To fix it, I have to forcibly power off the laptop and reboot, which is kinda annoying since then I lose anything I was doing, plus I fear of damaging the laptop.

How should I proceed to identify the issue and fix it?

did this happened too with 5.14 ?

It happened on Kernel 5.13 which was the default kernel
Since I thought it could be a kernel issue I tried with Kernel 5.15 but the issue is still there

Should I try with Kernel 5.14?

There should be something in the journal. Look at it and paste the important lines here.

After such event, run journalctl -b -1.

I guess it’s a power save feature where your laptop after some time in suspension tries to hibernate and it fails. The reason can probably be found in the log.

@mithrial
Just happened again. I might have some clue though. In the past days I have suspended my laptop many times without any issue. The difference being that now I closed the lid of my laptop.
On my HP Pavillion Gamin 15 the lid is bugged, it doesn’t suspend/resume on lid close/open.
To fix it I created this script:

[Unit]
Description=HP setkeycodes fix

[Service]
Type=oneshot
Restart=no
RemainAfterExit=no
ExecStart=/usr/bin/setkeycodes e058 142 e057 143

[Install]
WantedBy=rescue.target
WantedBy=multi-user.target
WantedBy=graphical.target

Could it be the cause of the black screen?
