[SOLVED] can't get output from HDMI no matter what

geckopot · 2024-06-27 00:33:43

I installed Arch Linux last night, and its my first time using Linux as a whole, so sorry if any of this sounds dumb.

I followed the guide, set up KDE plasma(kinda, I need to enter a command to get into it) with Wayland, all the things that I need to actually use Linux, but now when I turn on my computer today, there's no output.

Nothing, I can't see the Asus logo and the "press Del or f2 to get into BIOS" note at the bottom of the screen, there's nothing.

I've tried like 5 HDMI cords now, nothing seems to work. I'm using the nouveau drivers with an RTX 2060 super, if that helps. I also think I can still login and access the terminal, so maybe I can enter commands.

do you dual-boot with windows? if so: make sure fast start is disabled in windows' energy management

plasma usually comes with sddm - you maybe have to enable it: sudo systemctl enable sddm

No, I'm not dual booting, but I'll try that systemctl command

Try to enable sshd.

The monitor doesn't complain about "no signal"?
And at no point there's *any* display (eg. a white underline cursor etc)?

Backlight issue? You changed the cables, but have you tried a different monitor?

geckopot · 2024-06-27 08:19:34

No, the monitor does complain about no signal, sorry if I didn't include that. The only display is the monitor saying there isn't signal, if tried another monitor,, and it has a different message for no cable and no signal, so at the very least its detecting that there's some sort of display adapter.

I just tried logging into my account (I think) and the pc just turned off, everything is plugged in securely

It's reporting on the same condition - there's no signal and that's also true for the UEFI.

Does the system have a second GPU (IGP)?
What if you attach an output there?

geckopot · 2024-06-27 12:54:40

No, theres no other GPU or iGPU

seth · 2024-06-27 12:56:51

Do you have a spare GPU?

geckopot · 2024-06-27 12:59:24

No, I don't unfortunately

seth · 2024-06-27 13:03:03

Re-seat the GPU, make sure any dedicated 6/8-pin power supply is attached, try a different output (displayport? vga?)

geckopot · 2024-06-27 14:11:40

Yea, the PSU end is secured, the cable for the GPU end is a 6+2, reseatted the GPU, and tried a display port to HDMI cord, that doesnt work, still no signal.

The only other option I can do is maybe something like a HDMI/DP to VGA, but even then, I dont know when have I'll have the money for that.

How did you install Arch? Was there video for the install? It sounds like there is no video even before the boot sequence begins. Or am I missing something?

geckopot · 2024-06-27 14:20:09

I installed Arch directly from the official guide on this website. I could see Arch while installing it, setting up and using Plasma, and all the way up until I turnt off the computer, now theres just no signal coming from the GPU

cryptearth · 2024-06-27 14:45:32

an unclean shutdown seems not the issue here - a cold boot after power down should reset the gpu so the POST can cleanly initialize the vbios
it's somewhat disturbing that there seems no video during POST even before the bootloader starts

have you room to seat the gpu in another pci-e slot?
what may could help: remove the cmos battery while power is disconnected and wait a bit - this should clear the cmos and most of the nvram so the system should cold-init when power is reapplied

geckopot · 2024-06-27 16:16:26

Yea, that got me into BIOS, but now I think I know what the problem was. The bios wasn't detecting the SSD has a bootable device. Its on the storage list, but not listed as bootable. I think I'll just stick to Windows LTSC until I get a new motherboard and/or a new SSD. thank you!!

cryptearth · 2024-06-27 16:39:00

glad to hear you got video back - although I doubt that not detecting a boot drive was the issue here

seth · 2024-06-27 16:57:14

You probably screwed your ESP somehow, but if the only issue is that it's not flagged as bootable device, that's really just one fdisk away.
