switching to nvidia mode prevents X and sddm from starting.

[salperinlea]

Running: Arch, kernel 5.16.10. KDE 5.24.1 with SDDM. intel tigerlake / nvidia rtx 3060 hybrid. Of unknown relevance: 4K OLED screen.

After the reboot when I set it to nvidia mode, attempts to boot arch hang at a blinking white cursor. booting to tty works, at which point I can reverse the change, returning to hybrid mode.

Not sure if there are any logs I can post, but if there are, I'll submit them.

Can you try removing (/etc/X11/xorg.conf) and rebooting as that might fix the problem?

[salperinlea]

Doesn't exist -- removed it well before installing envycontrol.

Which init system are you using?

Try running sudo groupadd -G 33 nvidia_sddm ; usermod -G nvidia_sddm sddm

[salperinlea]

I think you mean to use -g and not -G for groupadd, since -G isn't a recognized option. That said, GID 33 is already taken on my system -- that's the http group. Is there a reason you suggested that GID or would any unused integer work?

Noting also: sddm has GID 973, with no members (but, my main user is in wheel, so no issue), and the group video, GID 985, has sddm as a member.

[salperinlea]

Well, trying that same command with a different number id, sadly, has no effect.

[bayasdev]

Hello there @salperinlea,

Can you send me the output of lspci and xrandr --listproviders commands when running on hybrid mode?

Greetings.

@salperinlea please remove xf86-video-intel package:

sudo pacman -R xf86-video-intel

Then switch to Nvidia mode again, thanks!

[salperinlea]

Hi @geminis3, Unfortunately, no change is accomplished by removing xf86-video-intel.

[kphanipavan]

https://github.com/geminis3/envycontrol/blob/main/envycontrol.py#L176

Here the program adds NVIDIA-0 as an output source to the display manager startup script

But @salperinlea 's xrandr provider list contains NVIDIA-G0, with a 'G'. Does that make a difference?

I myself am struggling with getting Nvidia GPU working as primary GPU for the past the week. I had NVIDIA-G0 in the provider list as well and adding G0 worked for me but I didn't test it with just 0.

Can you see if changing NVIDIA-0 to NVIDIA-G0 works??

NVIDIA-0 means your dGPU is the output source provider aka primary GPU so there should be something wrong on the generated Xorg config, please send me the output of the lspci command as well as your /etc/X11/xorg.conf file when on Nvidia mode,

OS: Fedora 36 KDE Spin, Fresh install. Nvidia Drivers: Installed using https://github.com/t0xic0der/nvidia-auto-installer-for-fedora-linux

Haven't used EnvyControl yet.

My nvidia.conf:

#This file is provided by xorg-x11-drv-nvidia
#Do not edit

Section "OutputClass"
        Identifier "nvidia"
        MatchDriver "nvidia-drm"
        Driver "nvidia"
        Option "AllowEmptyInitialConfiguration"
        Option "BaseMosaic" "on"
        Option "PrimaryGPU" "yes"
EndSection

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

My /etc/sddm/Xsetup file:

#!/usr/bin/sh
# Xsetup - run as root before the login dialog appears
xrandr --setprovideroutputsource modesetting NVIDIA-G0
xrandr --auto

The above setup works for me. The display runs on the Nvidia GPU without any issues.

The 'G' part looked different compared to other online sources, so I thought it might be causing some issue...

My System:

Acer Predator Helios 300 2021 Intel 10th gen i7-10870H Nvidia RTX 3060 Mobile FHD Non-Gsync Display

[adhamsalama]

The same happens to me on a fresh Fedora 36 KDE Spin, fresh install.

Copying @kphanipavan's /etc/sddm/Xsetup file solves the issue.

[joeg1484]

Just to add to this list... Same with me.. Fresh install of Fedora 37 - nvidia only mode doesnt work on KDE... GDM/Gnome seems to work fine.

Ill try the sddm fix to see how that works

[joeg1484]

So ... yes, this worked... I had to add G0 for mine as well... However, does the Xsetup file keep those lines in it when I switch to hybrid as well?
