[SOLVED] NVIDIA not working, xrandr shows only one monitor

HarisGusic · 2021-05-17 15:07:35

Ever since I installed Arch Linux about 1.5 years ago, I have had a problem with my nvidia graphics card. I have tried a few times to fix it, but I have given up every time because I never really needed extra performance out of my laptop. But recently I have started using more graphics intensive software and I also want to setup dual monitors: the built-in one from my laptop and an external monitor connected to the laptop via HDMI.

In the past few days I have been tinkering with my xorg.conf, unable to fix my problem. But I have come across a phenomenon that I haven't seen mentioned in any forum I have checked.

It is unlikely that this is due to a recent system update because I noticed this last year while I was messing with xorg.conf, but I lost track of what I did and I couldn't reproduce it until now.

Here's my xorg.conf. The commented parts are my attempts to fix the issue and are taken from various forums. I included them in case they can give additional insight and reduce duplication of effort. I did not necessarily include all of the commented lines at once in my attempts.

Section "Device"
	Identifier "nvidia"
	Driver "nvidia"
	BusID "PCI:1:0:0"
	Option "AllowEmptyInitialConfiguration"
EndSection

Section "Device"
	Identifier "intel"
	Driver "modesetting"
	BusID "PCI:0:2:0"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device "intel"
	Option "AllowEmptyInitialConfiguration"
EndSection

#Section "Module"
#	Load "nv-control"
#EndSection

# Section "ServerLayout"
# 	Identifier "layout"
# 	Option "AllowNVIDIAGPUScreens"
# EndSection

#Section "Screen"
#	Identifier "Screen0"
#	Device "intel"
#	GPUDevice "nvidia"
#	Option "GlxVendorLibrary" "nvidia-libgl"
#	Monitor "Monitor0"
#	Option "AllowEmptyInitialConfiguration"
#EndSection

#Section "Screen"
#	Identifier "Screen1"
#	Device "intel"
#	Monitor "Monitor1"
#	Option "AllowEmptyInitialConfiguration"
#EndSection

# Section "Monitor"
#	Identifier "HDMI-0"
#	Option "Primary" "true"
# EndSection

#Section "Monitor"
#	Identifier "eDP-1"
#EndSection

#Section "OutputClass"
#	Identifier "nvidia"
#	MatchDriver "nvidia"
#	Driver "nvidia"
#	Option "AllowEmptyInitialConfiguration"
#	ModulePath "/usr/lib/nvidia/xorg"
#	ModulePath "/usr/lib/xorg/modules"
#EndSection

When I run startx with this config everything gets displayed on my laptop screen. 'xrandr --listmonitors' displays the following:

Monitors: 1
 0: +*eDP-1 1920/344x1080/194+0+0  eDP-1

However, if I change the "Screen" section like this (change entry Device from "intel" to "nvidia"):

Section "Screen"
	Identifier "Screen0"
	Device "nvidia"								# This line has changed
	Option "AllowEmptyInitialConfiguration"
EndSection

and then run startx, everything gets displayed on the external monitor. When I run 'xrandr --listmonitors' I get this:

Monitors: 1
 0: +*HDMI-0 1680/433x1050/270+0+0  HDMI-0

In either case, xrandr shows me only the monitor that the output is to. This is the only thing that I didn't come across anywhere else on the internet.

There are other issues as well. For the remainder of this post, I will refer to the former configuration as the INTEL case and with the latter as the NVIDIA case.

1. I can't run 'nvidia-settings' in the INTEL case. It doesn't open and I get the following output (with --verbose):

https://pastebin.com/rDW7rGTz

In the NVIDIA case, nvidia-settings opens fine.

2. 'prime-run glxinfo' displays the following errors:

a) In the INTEL case:

name of display: :0
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  50
  Current serial number in output stream:  51

b) In the NVIDIA case:

name of display: :1
X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  156 (NV-GLX)
  Minor opcode of failed request:  4 ()
  Resource id in failed request:  0x1a00003
  Serial number of failed request:  41
  Current serial number in output stream:  41

3. 'gputest' always shows this, whatever demo I run:

4. 'prime-run gputest' -- there seems to be a problem with OpenGL?

5. Output of 'nvidia-bug-report.sh'

You can see it here: https://pastebin.com/NUqCsugK
I have noticed the following lines:

The only thing here that seems relevant is this:

The important bit is the output redirection w/ xrandr, check "xrandr --listproviders" to see yours for accurate indexes/symbols

Not sure about the prime-run situation, though.
Please post a complete Xorg log on your current/updated xorg config.

I have copied the configuration and done all the steps from the section you
linked. Another problem was that the nvidia modules were not loaded for some
reason, but after adding them to mkinitcpio.conf, everything works like a charm.
Both monitors work and prime-run also seems to work. Xorg logs do not report any errors.
Thank you. You have savedme hours of work!
