[SOLVED] Issue with secondary screen

SyntaxError · 2017-08-14 07:14:21

Hello!

I have been having some issues with my Alienware 13 laptop and the current issue is that I can't use more than one screen.
When I plug in my HDMI cable to the back of the computer the secondary screen lights up for a second indicating that a cable has been plugged in but then it returns to being black again.

As my computer is one of those hybrid graphic ones (nvidia and intel) I have installed both the nvidia (nvidia) driver and the intel driver (xf86-video-intel) I've also installed bumblebee, the Intel driver seems to be the one loaded at boot by the system as it's the only one in use (out of the two) according to lspci -v and after running modprobe nvidia the module is successfully loaded into the kernel, but the secondary screen still doesn't turn on when re-plugging it in again.

The nvidia settings programs (nvidia-settings) returns an error when I launch it ERROR: Unable to find display on any available system

I'm running gnome 3.24.2 if that helps.
I am actually first seeing this now but gnome informs me in All Settings-> Details that graphic is "Unkown"

The lspci output below is the output gathered after running modprobe nvidia

If you need more output from the system, just tell me and I'll add it to the post.

Is there anyone who can help me with this?

Make sure you start GNOME on Xorg as opposed to wayland, then look at https://wiki.archlinux.org/index.php/Bu … VIDIA_chip

Sadly that did not work, I switched over from wayland to xorg and ran intel-virtual-output but it just outputted No VIRTUAL outputs on ":0". it outputs the same on wayland.

I found this link and I've added the 20-intel.conf that was mentioned but that didn't change anything.

I remember way back, a couple of years ago when I ran arch on a desktop computer with two screens, I did tho use cinnamon and not gnome.

Could the issue be related to gnome, or is it the fact that cinnamon might have used Xorg opposed to wayland?

Log into an Xorg session and post your xorg log as well as the output of "xrandr" (with the second monitor plugged)

An issue I'm noticing is that sometimes Xorg won't let me login in, but returns me to the login prompt of gdm again. But then sometimes it let's me in without any issues.

I saw that there is a Xorg.1log and a Xorg.8.log so I'm including them as well just in case.

You're currentl on wayland (ie. the xrandr output is meaningless).
The Xorg logs indicate fatal errors "No devices detected" - the reason is very likely /etc/X11/xorg.conf
Get rid of that file, *especially* if you've used the nvidia tool to generate it.

I'm not gonna go into why gnome booted with wayland and not Xorg even when I picked it to use Xorg in gdm.
Anyway removing the xorg.conf file did the trick and now the xrandr output looks a bit more correct.

Just going to chime in on a small side thing, pastebin.com is blocked by some ISPs. It doesn't seem to be an issue for the people helping you in this thread, but for the future you should use a different service, like bpaste or whatever. Also, the text you are sharing is short enough to be pasted directly to the forums between code tags.

On your problem, xrandr doesn't list your second screen. Now that you have xorg working, try V1del's suggestion.

Thank you guys for helping me, it's solved now!

I'll keep the code tags/pastebin in mind fsckd
