PostPosted: Tue Sep 05, 2023 3:58 pm    Post subject: GDM login loop Reply with quote
After an update several months back, I haven't been able to use GDM to login to my machine. I figured it was the update's fault back then and decided to wait for a solution... today, it's still a problem.

I can log into gnome using SDDM, but I lose some basic items (no screen lock). I've been able to use SDDM and x11, GDM was using wayland until the update.

Looking at my logs, GDM appears to be attempting to run X now (even though it has been told to use wayland) and runs into an error:
Code:

I have no idea why it's trying to use X, why it fails, or what I can do about it.

For wayland support, I have the following in my dracut.conf:
Code:
add_drivers+=" nvidia nvidia_drm nvidia_modeset nvidia_uvm "

I have the following in my /proc/cmdline:
Code:
iommu=on intel_iommu=on rd.luks.uuid=luks-eb86ed8d-2955-4d28-b577-fc4ea8130582 rd.luks.uuid=luks-1696a19c-1750-4ce5-96bd-cf38d984532a dozfs root=zfs:AUTO rootfstype=zfs delayacct modprobe.blacklist=nouveau nosplit_lock_detect split_lock_detect=off nvidia-drm.modeset=1
(demonstrates that nvidia-drm.modeset=1 is in fact passed to the kernel at boot time). My /etc/gdm/custom.conf file:
Code:
# GDM configuration storage

[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=true

[security]

[xdmcp]

[chooser]

[debug]
# Uncomment the line below to turn on debugging
Enable=true
... and I have /etc/udev/rules.d/61-gdm.rules symlinked to /dev/null. Why am I restricted to only using SDDM now?

To be honest, I had GDM and Gnome on a media computer running Gentoo, and at some point an update broke... everything. But GDM would behave much like you described. So I just ditched it in favor of LightDM. Maybe give that a try?

gdm has a wayland USE flag. What is the output of emerge -vp gdm?

I was going to suggest trying to downgrade it, but that's the oldest version in ::gentoo. Seems like a bug to me.

I don't see any relevant open bugs, and my lack of git knowledge only reveals "routine" recent activity.
