Computer recognizes 2nd monitor, but sends nothing to it

hmm if you mind you can send me boot log in pm not posting it public (it includes serials and uuids)
journalctl -b -0 | eos-sendlog

I’m struggling to figure out how to send a PM lol

click on my avatar and there click “Message”



Either I’m blind or there’s no Message button

Did you click on the avatar?

I did, that’s the first picture that I attached. Interesting that you see it and I don’t. Is it perhaps because I’m a new user?

Have you put the command that arandr produces into a terminal to see if you get any output?

No output is provided.

If I add the --verbose flag

crtc 0:    1920x1080  60.00 +0+0 "HDMI-0"
crtc 1:    1920x1080  60.00 +1920+0 "DVI-D-0"

So from here, go into the Layout menu. Click save, name the file what you want to call it. I’d save it to Downloads.

Open the script that arandr produced.

Can you please paste that here.

#!/bin/sh
xrandr --output DVI-D-0 --mode 1920x1080 --pos 1920x0 --rotate normal --output HDMI-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output DP-0 --off --output DP-1 --off --output DP-2 --off --output DP-3 --off --output DP-4 --off --output DP-5 --off

Maybe removing all the cruft at the end may help.

xrandr --output DVI-D-0 --mode 1920x1080 --pos 1920x0 --rotate normal --output HDMI-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal

Post that in a terminal and let me know if the monitors work correctly.

No output nor change

Post the output of xrandr please.

Actually, I see you have a nvidia card.

I used this package here to install nvidia drivers with great success.

Maybe you could give that a shot and then see what happens with arandr/xrandr?

does xrandr give an output for you when it doesn’t change anything and there’s no errors?

Running just xrandr for me gives this output:

I just want to see what resolutions etc you have available.

This might be a silly question, but is xrandr installed?

I should’ve specified with “when provided with arguments like mine” to my question I guess lol

This should have worked.

Just so I am caught up, you use nvidia? What drivers are you using?

I have had great success with the drivers from the link I added above, could be worth trying.

Ha! Yeah, it’s all good.

I believe your issue is driver related, though I must make it clear, I am not expert this is just from my experience.

Like I said, from Xorg’s perspective, everything is fine. I can move my mouse to the other monitor. I can send workspaces and windows over to it. Despite that, my monitor doesn’t get any signal from my computer.

I do think that is probably the case

I probably going to have to bow out at this point. I have exhausted my knowledge.

Other than purging all previous drivers and using the ones I linked above I have nothing else to offer I’m sorry.

I feel your pain, sorry I can’t be of more help. If I was in the first place lol.
