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 sounds like the issue is with the lid latch/sensor, not with the graphics. Some laptops may not boot if the lid is closed, and some have options on the firmware to enable to boot when the lid is closed / on a docking station.
I don’t think this is the problem, as it refuses to boot even when the lid is open
That is why I also mentioned the latch/sensor, it may got stuck.
What do you mean? Like if the lid is open, but it thinks it’s closed?
This seems unlikely since it boots with a monitor attached. From past experience most laptops that refuse to boot while closed don’t boot even if an HDMI display is connected.
