 |
|
Hello, I would like to ask a question today. Actually, is it possible to use a wayland session with the proprietary nvidia drivers ? Because of security, and performance as well, when it will be possible to use my nvidia graphics with the propriety driver, I will swithc to wayland.
I know actually it's possible in Fedora (I tried already)
(I use KDE) |

I run gnome 42 on nvidia, wayland. and I ran kde-plasma under wayland and it worked well.
the only discomfort is that after any kernel compilation need to issue emerge -av @module-rebuild
both kde-plasma and gnome with wayland can be a daily driver |

| Okay ! And no special configurations are needed ? Because I have a laptop with intel graphics cards+ nvidia dedicated GPU |

Nothing special. Everything by default. | Code: | | USE="networkmanager vaapi wayland screencast -semantic-desktop" |
Default profiles desktop/plasma or desktop/plasma/systemd – depends on init system
I run a laptop with nvidia prime. The only thing is that I observe problems with suspend when nvidia card is present in system and init system is openrc. Did not observe with systemd. That's why I created two boot options, one default with nvidia's pci turned off (so the system does not even know about it) – this is for work, watching films, reading books – activities where the lid can be closed\opened several times a day; and the second boot entry does not delete the card – this is for games (games usually do not require suspend functionality).
So, by default nvidia card is absent in my system (not visible in lspci), and I can be sure it will not make a surprise when for example, I'm working |

nvidia gave a list of caveats, but it generally works for simple setups (may need to fiddle a bit more if want to use something like wlroots/sway rather than gnome/kde which are more serious about nvidia support, given speaking of KDE it should generally be fine).
and yep, as long as got USE=wayland and VIDEO_CARDS=nvidia (which is used to enable nvidia-specific wayland stuff on a few packages, but not super important now that it can use GBM) it should just work out of the box if there's nothing special about the system (e.g. some dual gpu / offloading setups), gnome/gdm even defaults to wayland even with nvidia then. |

Sorry to come back to this old topic, but I didn't specifiy I would like to start a wayland session on KDE desktop with Optimus.
Actually if I start a wayland session, KDE use only the intel graphic card.
How I should do ?
I would like to use the proprietary graphics cards driver of NVIDIA
