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? Enviado do meu iPhone
