== Summary == Enable Wayland sessions by default in GDM even with the NVIDIA proprietary driver.
== Owner == * Name: [[User:ofourdan| Olivier Fourdan]] * Email: ofourdan@redhat.com
== Detailed Description == Recent updates in NVIDIA proprietary driver allow Xwayland to benefit from hardware acceleration and X11 applications can have their rendering hardware accelerated.
That allowed to enable Wayland sessions even when the NVIDIA proprietary driver is used, but keeping Xorg the default in that case.
This proposal is to make Wayland by default with newer versions of the NVIDIA proprietary driver to remain consistent with other drivers.
GDM already has a set of udev rules which check for the driver and its version, so this would only require a tweak in the udev rules to make Wayland session the default with the next version of the NVIDIA driver [https://gitlab.gnome.org/GNOME/gdm/-/blob/main/data/61-gdm.rules.in].
Note that currently Xorg is also preferred in the case of multiple GPU, this would remain the case with this proposal.
This change is just about changing the default with NVIDIA proprietary driver on supported configurations, “GNOME on Xorg” still remains an option, just like with other drivers.
== Benefit to Fedora == Fedora has changed to Wayland by default since [[Changes/Login Screen Over Wayland|Fedora 22]], but the NVIDIA proprietary driver has been an exception ever since (either because originally Wayland would be disabled with NVIDIA drivers, or more recently Xorg would be used by default).
Currently, when first installing Fedora on NVIDIA hardware, users get Wayland by default with the Open Source "nouveau" driver, with Xorg being an option in the login screen. If they later decide to enable the rpmfusion repository and install the NVIDIA proprietary driver, they get Xorg by default and Wayland as an option.
This change would make the default consistent regardless of the driver, for single GPU systems.
== Scope == * Proposal owners: Tweak the gdm udev rule to enable Wayland with the NVIDIA proprietary driver above a given version [https://gitlab.gnome.org/GNOME/gdm/-/blob/main/data/61-gdm.rules.in#L7-17] * Other developers: [[User:Rstrode| Ray Strode]] for reviewing the changes in the udev rules from GDM * Release engineering: This change doesn't affect release workflow * Policies and guidelines: This change doesn't affect packaging guidelines * Trademark approval: N/A (not needed for this Change) * Alignment with Objectives: No
== Upgrade/compatibility impact ==
== How To Test == # Requires an NVIDIA GPU supported by the recent NVIDIA proprietary driver and `nvidia-drm.modeset=1` set in the kernel command line to enable KMS [http://us.download.nvidia.com/XFree86/Linux-x86_64/495.44/README/kms.html] (rpmfusion packages for the NVIDIA driver do that automatically) # Enable the rpmfusion “nonfree” repository to install the NVIDIA graphics drivers [https://docs.fedoraproject.org/en-US/quick-docs/setup_rpmfusion/] # Install the NVIDIA proprietary driver (and the `xorg-x11-drv-nvidia-power` package for suspend/resume support - see [https://rpmfusion.org/Howto/NVIDIA?highlight=%28%5CbCategoryHowto%5Cb%29#Sus...] and [http://us.download.nvidia.com/XFree86/Linux-x86_64/495.44/README/powermanage...] for more details) from the rpmfusion repository # Reboot the machine # Ensure graphical login screen comes up # Try to log into a "GNOME" session # Check whether this is a "GNOME on Wayland" session (both `$DISPLAY` and `$WAYLAND_DISPLAY` are set) # Log out # Try to log into a "GNOME on Xorg" session # Check whether this is a "GNOME on Xorg" session (`$DISPLAY` is set, `$WAYLAND_DISPLAY` is not set)
== User Experience == Users with NVIDIA hardware and NVIDIA proprietary driver installed will get a Wayland session by default when selecting the "GNOME" session in the login screen.
== Dependencies == This depends on the NVIDIA proprietary driver and its support for Wayland.
Typically, this proposal would change the default in a future version of the NVIDIA driver which is not released yet.

Night light does not work with NVIDIA running Wayland: - https://gitlab.gnome.org/GNOME/mutter/-/issues/290 - https://forums.developer.nvidia.com/t/gnome-night-light-not-working-under-wa... Until this is fixed, I do not think Wayland should be the default.

Crashes with Qt+Wayland and WebKit/Blink/QtWebEngine+Wayland need to be fixed first.

Hello!
I'm a user of NVIDIA graphic card.
On top of what others said, I add that there is also the nvidia-settings GUI that does not work on Wayland.
I don't use it personally, but other people can use, for example, application/game profiles.
It is also something to consider...

The nvidia-settings app requires some support from NVIDIA to work under Wayland. There is nothing Fedora can do to make it work.

Be that as it may, we should not be defaulting to a configuration which causes significant usability regressions. Is some collaboration with NVIDIA planned in order to fix these? My post to nvidia developer forums about broken night light did not get any official response.

Judging about what's going on in Mutter upstream[1], I would say they're furiously working on uplifting NVIDIA GBM Wayland mode for GNOME 42.
[1]: https://gitlab.gnome.org/GNOME/mutter/-/commits/main
I know that "Fedora" cannot do it. I didn't made any request.
The point is that this proposal can be canceled/reverted if the nvidia-settings GUI does not work on Wayland on time, or depending on what others think about the use of nvidia-settings.
And... Please don't imagine things I didn't say... (take it fairly).
Should it work in KDE/Gnome,etc?

@ Reon Beon
I don't really know what you are asking ... If there is an issue with your monitor refresh rate, or changing the refresh rate does not work in any desktop environment, maybe open an issue in a window manager bug tracker (e.g. in mutter gitlab) with the whole configuration of your PC. Even if this is not a problem with a window manager, their developers may be more helpful in diagnosing the problem.
