Lately, when booting up my linux machine (Fedora 39 KDE), everything looks good until about 30s after I log in. Then both screens go black with no output, and shortly after that they light up as if there is a signal but I don’t seen anything.
I’ve tried accessing a TTY but nothing changes on the displays. The only solution I can find is pressing the reset button on the PC, and then I have no problem on the following boot. I’m not really too sure where to start looking regarding solutions. Would really appreciate any input you guys have to solving this problem.
First thing I would do is activate the SSH server so that you can still access the PC with the broken display.
Do you have an nVidia card and/or use Wayland? If you have an nVidia card reinstalling the drivers might be enough although it doesn’t sound like the common problem that the kernel module isn’t built for the current kernel.
I just did a kernel update. I’m gonna see if that fixes it, but enabling the SSH server is a good idea. Thanks for the suggestion
