Hi, I’m making this post today because I’ve been having some problems with Nvidia drivers with wayland. Looks like nvidia driver 535 was having some issues with Godot (flatpak), the error was something about Vulkan, anyway, it’s not important now.

The versions 535 and 545 of the nvidia driver have been causing some problems on my machine while using wayland, so I’m making this tutorial for the folks that are encountering problems and wish to change their driver version to (hopefully) solve their bugs while waiting for the latest driver to be updated.

Let’s get started.

DISCLAIMER: I am not responsible if you break your installation or if you damage your machine in any way.

1st step

First of all, I highly advise to install Timeshift. It’s a neat program that will make a snapshot of your system configuration (depending on how you configure it) so you can roll back in time if something goes wrong. It saved my linux installation many times.

2nd step

If you wish to see your current driver version, open a terminal and type:

$ nvidia-smi

I advise to write the version down, or at least remember it.

3rd step

To view all the nvidia drivers you can install, open a terminal and execute:

$ ubuntu-drivers list

or

$ ubuntu-drivers devices

These 2 commands (you can use whatever you prefer) will tell you all the nvidia drivers that are available for installation.

To delete your current nvidia driver, open a terminal and execute:

$ sudo apt purge ~nnvidia

Then, you can install one of the nvidia drivers we have seen before, for example:

$ sudo apt install nvidia-driver-535-server

(If I understand correctly, the server drivers are no different from the normal drivers, other than the fact that they are supported for longer and they should in teory be more stable).

4th step

After your new driver is installed, you can reboot your machine, using the UI or the terminal by executing:

$ sudo reboot

5th step

If you want to use X11, you’re done. If you want to use Wayland, you have to do some additional steps.

To enable wayland in pop-os, you first have to enable nvidia modeset if it’s not already enabled.

To check if it’s enabled, you can go inside /etc/modprobe.d/ and check if any of the files contains options nvidia_drm modeset=1. If you find nothing, you have to create the file yourself.

To do this, execute:

$ sudo nano /etc/modprobe.d/zz-nvidia-modeset.conf

The content of this file should be:

options nvidia_drm modeset=1

Then execute:

$ sudo update-initramfs -u

6th step

To be sure that there is nothing else blocking your machine from enabling wayland, execute:

sudo nano /usr/lib/udev/rules.d/61-gdm.rules

Inside this file there are some rules, some of which may stop your system from displaying the wayland option inside the little gear in the login screen.

Specifically, you have to check these lines:

LABEL="gdm_prefer_xorg"
#RUN+="/usr/libexec/gdm-runtime-config set daemon PreferredDisplayServer xorg"
GOTO="gdm_end"

LABEL="gdm_disable_wayland"
#RUN+="/usr/libexec/gdm-runtime-config set daemon WaylandEnable false"
GOTO="gdm_end"

LABEL="gdm_end"

Check that the lines starting with “run” are commented out.

7th step

We are almost done.

Execute in the terminal

$ sudo nano /etc/gdm3/custom.conf

Here you will find a line like this

# Uncoment the line below to force the login screen to use Xorg
# WaylandEnable=false

You can leave it as is, but if you can’t see the wayland option in the login screen, you can come back and edit it like this:

# Uncoment the line below to force the login screen to use Xorg
WaylandEnable=true

8th step

You can reboot your machine, and when it boots back up, you should hopefully see the wayland option in the bottom-right gear in the login screen.

9th step

Don’t forget to run:

$ flatpak update

To allow flatpak to install the new version of the nvidia driver for your flatpak software.

Final

I hope you found this tutorial useful. If you want you can suggest improvements, or edit and share it on other platforms if you want more people to see it.

    By the way, if you’re curious of the issues that are currently present in the latest nvidia 545 driver, here is a thread from the nvidia forums.

    There is currently no fix.

    If you follow the thread, there are links to other 2 threads with people experiencing similar issues.
