From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Those who are using Nvidia's driver 555, what's your experience in Wayland so far? Those who are using it in conjunction with KDE 6.1, what's your experience with multi-monitor VRR in Wayland? (lemmy.ca)

I currently have an AMD video card (6700 XT) and Wayland support is excellent. Also, multi-monitor support in Wayland works perfectly.

So what's your experience with Nvidia's 555 driver in Wayland? Those using it in conjunction with KDE 6.1, what's your experience with multi-monitor VRR? I ask about VRR because I heard that multi-monitor VRR in Wayland is still problematic.

This is for my own curiosity if an Nvidia video card could be considered as an upgrade option.

VRR does not work if you have a NVIDIA card and more than one monitor enabled. If you disable extra monitors it'll work, but that's hardly a workaround (and it's one of the main reasons I'm still on Windows).

I'm also getting a lot of xwayland crashes while playing or simply when trying to drag a window, those crashes freeze my entire PC and I have to reboot.

To be fair, most, if not all of my issues preventing me from fully moving to Linux seem to be fixed by using an AMD card, but I'm not in the market for a new card (I have a 3080) nor do I want to lose DLSS, which is a game changer to me.

VRR does not work if you have a NVIDIA card and more than one monitor enabled.

I recently learned that's not entirely correct for Wayland. The critical thing is that VRR stops working if more than one enabled monitor is connected to the NVIDIA GPU. Meaning that if you connect only one display to the NVIDIA GPU and the other monitors to the integrated GPU it should just work.

I felt pretty stupid when I realized that I could've just switched a single cable and be using VRR way earlier. Didn't even need a reboot to work. For reference, I'm using a NVIDIA GPU + AMD CPU with 1 G-Sync as my main monitor and one non-VRR as my secondary monitor.

That... Makes sense, really. And how would you do on about it? Just switching the cable to the motherboard IO? No need to use stuff like optimus?

Sadly I will have to live with this issue since my 5900x has no iGPU, but I do plan to upgrade to a 7800x3d

Yup. I've never done anything besides installing NVIDIA drivers. Just switching the cable of the secondary monitor to the motherboard ports and it just worked. No reboot even, just making sure that adaptive sync is enabled in KDE or wherever.
