[SOLVED] Screen stays black when using integrated graphics

Amaury · 2019-06-23 17:44:19

I'm using a laptop that has Intel integrated graphics, and nvidia (quadro K2000M) discrete graphics.
Until now, I was only using the integrated graphics without even knowing it using Nouveau drivers (which came automatically with X or mesa I think ?).
All was fine except I had poor performance when running a game, so I decided to try installing my nvidia drivers.
I followed the nvidia optimus / nvidia-xrun wiki pages, and I can now run nvidia-xrun from a tty to start Xfce4 with the Nvidia graphics (nice !)

But now any "normal" X session is just a black screen. That is the default LightDM session (on boot when systemctl set-default is graphics.target), and when I run xinit from a tty.
But behind the black screen, I can tell there's actually Xfce running because I could hear a sound play when blindly opening VLC.

Here's the stderr of xinit (run from a tty), which I manually killed from the tty. I tried to remove all useless information, and I translated some things from french.
I don't really know if there's a better way to find clues.

Has anyone an idea on how I could fix this ?
Thank you very much in advance.

According to the NVIDIA Wiki, the K series should be using the nvidia package and not the optimus nor nvidia-xrun as you did. Have a look at that wiki.
And check that you are using the discreet graphics in the BIOS.

Thank you for your help.
I made sure I was using the nvidia (and nvidia-utils) package and having discrete graphics in the BIOS.
Unfortunately the computer freezes on the message "Starting Arch Linux" (printed from the Grub command I think)

So I went back to Integrated Graphics, and ran nvidia-xconfig (seen in the wiki).

Not only did nothing change on Discrete Graphics (freeze) but now Integrated Graphics never starts LightDM like it used to. It stops after printing Reached target Graphical Interface

I think I could fix one of these from the grub command, but I don't know at all what to do there.
Also I don't know if I can at least go back to multiuser.target to access a command line. Because right now the computer is completely unusable.

That almost always only makes things worse. The few other times it has no effect at all.

Thank you now I can access a tty.

When the BIOS display setting is Discrete Graphics it freezes on the "Starting Arch Linux" print, no matter the target (multi-user or graphics).

When the display setting is Integrated Graphics I can access a tty with multi-user.target. From there xinit fails with the error "no screen found" (even when an external monitor is connected).
nvidia-xrun works, and starts Xfce. The integrated graphics are used (not the nvidia GPU), and the external monitor is never recognized.

When the setting is Nvidia Optimus I can also access the tty.
With graphics.target, LightDM starts normally only on an external monitor. My laptops screen is not recognized at all, but is used for the tty if I press Ctrl+Alt+F2. The Nvidia GPU is used.
When I run xinit from the tty (with multi-user.target), no error is shown but the X server stops immediately.
When I run nvidia-xrun from the tty, Xfce starts and works with dual monitor. But for example notifications don't work.

What I would like is graphics.target (so LightDM) to work on any screen (most importantly my laptop screen).

Is the static xorg conf still there?
Xorg logs?

Amaury · 2019-07-17 15:13:45

When starting graphics.target in Optimus mode, I have Xorg.0.log and Xorg.1.log

At some point it says that it can't access nvidia-xorg.conf but it does exist in /etc/X11/

Here is xorg.conf and nvidia-xorg.conf (they are the same) :

Using config file: "/etc/X11/xorg.conf"

Remove that, it's gonna impede any approach to use the nvidia chip as a secondary device and causes the failures w/ the "Integrated Graphics" configuration.

The log "complains" about a missing "nvidia-xorg.conf.d" - which is irrelevant.

Xinit will most likely fail because you didn't configure xinitrc nor have twm nor xterm installed?
https://wiki.archlinux.org/index.php/Xinit#xinitrc

Lightdm will probably have configured the external output previously, https://wiki.archlinux.org/index.php/Li … ng_monitor

Amaury · 2019-07-17 16:49:54

I removed xorg.conf
Now "Integrated Graphics" works only with the laptop screen.
And "Optimus" works with laptop and external monitor.

So everything is fine and works as expected now.
I thank you very much for your help
