[SOLVED] NVIDIA as Primary GPU not working

speltriao · 2020-10-01 21:14:29

Hello, I'm using (pure) Arch Linux with linux-lts. I'm trying to use NVIDIA as my primary GPU (turning off intel graphics) in my laptop.

I installed nvidia-lts and ran nvidia-xconfig (exactly as suggested https://wiki.archlinux.org/index.php/NV … stallation).The installation succeeded.

After a reboot I followed this section (https://wiki.archlinux.org/index.php/NV … phics_only). My /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf, ~/.xinitrc and GDM are identical as in the manual.

After rebooting again, I get the following errors:

nvidia-settings

"ERROR: Unable to find display on any available system"

 nvidia-smi

 glxinfo | grep NVIDIA

returns nothing

The funniest thing is that this setup used to work last time I used Arch (2 months ago). Please, help.

Please post your xorg config and the actual output of "glxinfo" (at least "glxinfo | head -n60") so we can see what *is* being used.

~/.xinitrc and GDM are identical as in the manual

GDM doesn't use xinitrc - let's also see "loginctl session-status"

Thanks for the reply.

The proprietary NVIDIA graphics card driver does not need any Xorg server configuration file.

After reading this, I've formatted my HDD and reinstalled Arch Linux (just in case).

I've reinstalled linux-lts and nvidia-lts without running nvidia-xconfig. I also did https://wiki.archlinux.org/index.php/NV … phics_only again.

I'm also using LightDM and XFCE4 now because of ~/.xinitrc.

Still facing the same issue:

 glxinfo | head -n6

display: :0 screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4

 nano ~/.xinitrc

xrandr --auto

Please wrap the shell output in code tags, https://bbs.archlinux.org/help.php#bbcode

Also

- the first 6 lines tell little to nothing. But it already looks like you're using some mesa driver, likely on the intel chip.

Lightdm doesn't use xinitrc either, please see https://wiki.archlinux.org/index.php/Li … ng_monitor and also stop creating a moving target.
The session status is now irrelevant because you're not using wayland (on intel) for sure.

To get us an overview on the system you created, please post the entire xorg log as well.

The xorg log doesn't show any sign of using /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf .
post its contents and ls -lR /etc/X11/

Also look at the prime page again and scroll a bit down to find instructions how to setup lightdm to execute those xrandr commands.

Lone_Wolf · 2020-10-02 12:48:24

Looks like you setup things correctly.

I did notice that conf file will only work if nvidia-drm has finished initialising .
please reboot , post dmesg and/or journalctl -b , also fresh xorg log and your /etc/mkinitcpio.conf

speltriao · 2020-10-02 12:59:27

Thanks for the reply.

After a reboot:

My dmesg: https://pastebin.com/pN4XiPdz

My journalctl -b: https://pastebin.com/Q7MwujAt

My (fresh ) xorg log: https://pastebin.com/USS9rbRD

My /etc/mkinitcpio.conf: https://pastebin.com/KPQzhEAD

seth · 2020-10-02 13:38:47

The journal is missing the important parts in the center…
The X11 server still runs on the intel chip only, see https://wiki.archlinux.org/index.php/NV … de_setting add the kernel parameter and also move the modules into the initramfs for early KMS

speltriao · 2020-10-02 13:57:17

Thanks for the reply.

I followed the wiki and added nvidia-drm.modeset=1 to my GRUB /etc/default/grub like this:

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet nvidia-drm.modeset=1"

And then:

 sudo grub-mkconfig -o /boot/grub/grub.cfg

After a reboot, nothing changed. Neither nvidia-settings nor nvidia-smi.

Yes!!! This worked! Thank you.

I made a small .txt file with all the steps for this setting. Might be useful for future reference: https://pastebin.com/bZ1b9XA0

Thank you for your help and have a nice day!
