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!
It could be Linux, too. Some distros have fancy boot graphics - look for something called “plasma” - not the KDE one, but a different one - and uninstall or disable that. It’s a common thing that hides the boot log behind a logo-and-progress bar. Arch doesn’t use it, so I haven’t seen it in years, but IIRC it can cause problems on headless systems.
