Can't use Wayland with Nvidia 510 drivers on Ubuntu 22.04 LTS

Question

I installed the NVIDIA 510 drivers from the Additional Drivers app on Ubuntu 22.04. I also edited /etc/default/grub and added GRUB_CMDLINE_LINUX="nvidia-drm.modeset=1". Unfortunately, it didn't work. I can't see the little gear icon when I login.

Funnily enough I had 21.10 running before this install and it was working in Wayland after editing /etc/default/grub.

Here is my setup. It's a very recent Dell Laptop with Secure Boot enabled:

Answer 1

In the file /usr/lib/udev/rules.d/61-gdm.rules in my case, I just commented the last two one here

LABEL="gdm_prefer_xorg"
#RUN+="/usr/lib/gdm-runtime-config set daemon PreferredDisplayServer xorg"
GOTO="gdm_end"
LABEL="gdm_disable_wayland"
#RUN+="/usr/lib/gdm-runtime-config set daemon WaylandEnable false"
GOTO="gdm_end"

It did work on Ubuntu 22.04 or if still does not work, you can comment something that is related to it.

Two possible solutions:

1. Enable unreleased updates [ Alberto Milone ]

   • Default to Wayland for hybrid systems with Nvidia graphics drivers.
   • Default to Xorg but offer Wayland with the gear button on the login screen for non-hybrid systems with Nvidia graphics drivers. (LP: #1968929)

2. Workaround Create a file in /etc/modprobe.d/nvidia-power-management.conf containing the text:

   options nvidia NVreg_PreserveVideoMemoryAllocations=1
   

Otherwise, follow these bug reports:

Answer 3

Because /tmp is a tmpfs on my system, i need to set

options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp

in /etc/modprobe.d/nvidia-power-management.conf. After rebuilding initramfs with update-initramfs -u and a reboot, Wayland is working for me.

Answer 4

From this article:

sudo nano /etc/gdm3/custom.conf

Within this file, look for the line that says #WaylandEnable=false. You can uncomment this line and either set it to true or false, depending on whether you want Wayland enabled or not.

WaylandEnable=true
