Hello,
I recently installed Debian 12.8 on a laptop with an ONKYO motherboard with an i5 M450 processor. With Debian and any GNU/Linux that I had previously installed (Fedora and Kubuntu), there was a problem with the suspend resource. The laptop turns off by itself and only it starts working again when I turn it on, it resumes working from the point where it stopped, but it does this action indefinitely. I solved this problem via GRUB by disabling suspend. After that, the installation went on normally. However, when I started it and tried to log in, the screen turned off. If I had already selected a user and entered the password, even with the screen off, I was logged in and I used the system as that user which it works without any problems. Another way to go back to the login screen is to switch to a prompt screen and return to graphical mode, but this is only a paleative since it quickly returns to the previous situation. One thing I noticed (and it may have nothing to do with it) is that this behavior started happening after I connected a monitor to the laptop and switched the screen and at a certain point the screen kept in black every now and then. What am I doing wrong and how can I solve this problem?
I have Debian with KDE running just fine on an external monitor. When I need to use my webcam I switch the display configuration to unified output and the same image is displayed on both monitors. I have KDE configured to not suspend when the lid is closed if a monitor is connected. Also under battery and brightness I have "manually block sleep and screen locking" checked.
What desktop environment are you using?
Is the external monitor still plugged in?
How is the external monitor configured: unified, extended or primary?
You say you disabled suspend via grub? Have you tried disabling suspend in the BIOS? It will be S2 and S3 in BIOS.
When the device suspends I take it that you are not able to wake the device properly by pressing the power button?
