Hello! I converted an old laptop with a broken screen into a home server, and it all works well except for one thing: when I reboot it (via ssh), if no screen is connected, it will get stuck and refuse to boot. as soon as I connect an HDMI monitor, the fans will start spinning and it will start booting as usual. Then I can remove the HDMI and it will work flawlessly. I don’t know if this is a linux problem, a GRUB problem, or a firmware problem.
Any idea on how to solve this, or on how to fool it into thinking a screen is connected? The problem is not the lid switch as I removed the magnet from the screen, so it thinks the lid is always open
Thanks in advance!
There are a few ways to investigate, but for that we would need a bit more info. Firstly, what distro do you use ? Try using a different bootloader than GRUB to see if it solves the issue. Otherwise you could also try to use Linux’s UEFI stub.
So you think it’s a grub problem?
I’m running fedora 39
I don’t know what the problem is. I’m trying to rule things out one after the other.
Maybe try using systemd-boot instead of GRUB?
