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!
You just need to configure X11 to run in a headless mode. There’s a lot of guides showing how to do it for raspberryPi but I did it in Debian recently and it’s working fine, no dummy HDMI plugs needed. Look into xserver-xorg-video-dummy package. I don’t remember how exactly I set it up but I don’t see any specific configuration on my server so maybe installing this package is all it takes.
it gets stuck before grub showing, can this still be the fix?
Ups, sorry, missed the part about not even fans spinning. If it’s not even booting then X11 config will not help.
no problem, thanks for trying to help!
