GDM won't start i3 but will start Gnome - Xorg issue? [Solved]

Hello all,

First time posting and I hope this is the right place for this, but I am not having any luck resolving my issue. My machine is a Dell Inspiron 5577. I have gone through the steps on the Arch wiki here and here to setup Bumblebee for a Nvidia Optimus graphics card. Prior to setting up bumblebee I had a working installation of i3. Now everything seems to be working fine in Gnome, as I can use optirun to run a program on the dedicated GPU instead of the integrated GPU. However, I when switching to i3 (specifically i3-gaps) and logging in with my credentials from GDM I am just brought straight back to the GDM login screen. Even if I disable GDM and try "startx /usr/bin/i3" the machine just stalls until I press ctl+c to cancel the command. It does, however, state that there was an error and to check the "/var/log/Xorg.0.log" file for more information. The contents of that log file are:

It seems to me that i3 cannot find my laptop's screen? But Gnome has no problems finding it. I am at a bit of a loss as to what I am missing and am hoping someone here can point me in the right direction to get i3 up and working again.

You've an xorg.conf around (probably written by nvidia-xconfig) which tries to use the nvidia GPU, but that's initially deactivated by the bumblebee setup.
Move away that config.

Re: GDM won't start i3 but will start Gnome - Xorg issue? [Solved]

I didn't use nvidia-xconfig to generate that file as I had read others noting that it is not a very good tool. Instead I manually generated the file with these contents as per the Nvidia Optimus Arch Wiki page:

Section "Module"
    Load "modesetting"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "01:00.0"
    Option "AllowEmptyInitialConfiguration"
EndSection

I used this output from the "lspci" command to find my nvidia GPU BusID:

I also tried using my integrated intel GPU BusID "00:02.0". Both of these configurations as well as removing the xorg.conf file completely has produced the same results.

Any other thoughts?

Re: GDM won't start i3 but will start Gnome - Xorg issue? [Solved]

Yes, remove that file.
You've got it from the optimus section labeled "Using nvidia" - which you're not. You do, by your own account "setup Bumblebee for a Nvidia Optimus graphics card".

Re: GDM won't start i3 but will start Gnome - Xorg issue? [Solved]

I think you misunderstood. I have tried removing that file and it did not change anything. I also tried it with that file using two different BusIDs: one for the nvidia GPU and one for the intel GPU. None of these three configurations have been able to successfully start i3.

edit1: grammar

edit2: A follow up question. Since I am being told not to use the xorg.conf file from the "Using nvidia" section, should I also remove the two desktop files it had me create for GDM at these two locations:
/usr/share/gdm/greeter/autostart/optimus.desktop
/etc/xdg/autostart/optimus.desktop

Their contents are: 

[Desktop Entry]
Type=Application
Name=Optimus
Exec=sh -c "xrandr --setprovideroutputsource modesetting NVIDIA-0; xrandr --auto"
NoDisplay=true
X-GNOME-Autostart-Phase=DisplayServer

edit3: Removing the above desktop files does not seem to change anything.

Re: GDM won't start i3 but will start Gnome - Xorg issue? [Solved]

New xorg.log after having moved all these files away?

Also for completeness sake, it shouldn't be working fine with gnome either, however that is likely masked by the fact that you are starting GNOME on Wayland as opposed to xorg.

I checked to see if xorg or wayland was being used for Gnome and it in fact was being powered by wayland. Attempting to log in with gnome on xorg gave the same results as trying to log into i3.

Re: GDM won't start i3 but will start Gnome - Xorg issue? [Solved]

Move away the /etc/X11/xorg.conf.d/20-nvidia.conf?
(/usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf should be from nvidia-utils and not kick in here because nvidia-drm shouldn't be loaded)
