What are you running exactly? I haven't been able to get a 144hz + 60hz setup working with KDE on X. The main monitor just doesn't want to do 144hz, even if I disable the other one via xrandr. My 1070 Ti has me afraid of wayland because the nvidia driver already breaks something once a month.

I just bit the bullet and moved to Wayland. I've heard mixed things about people on 10-series hardware, but things work pretty well on my 3070Ti. My guess is that the drivers are slightly different across generations, and parity still hasn't been a priority. I decommissioned my 1050 back in my x11 days, I wish I could tell you how well it worked with my current setup.

I'm also running everything on NixOS, so assume there's a fair bit of fairy dust blessing the config. Besides enabling modeset and cudatoolkit manually though, I don't think there's much special about my software setup.

I definitely noticed the driver issues increasing as my GPU got older. On windows I spent hours looking for driver versions that work with all my games and then didn't update for months.

If it wasn't for AI, I'd upgrade to AMD right now. But ROCm and the CUDA translation layer don't quite seem to be there yet.

Be afraid.

I tried to get my 3090 working in Wayland/KDE/Arch for about a month (after repeatedly running into the same issues on my 2060 laptop) and gave up.

AMD IGP output it is... and I just game on Windows instead. But even then, neutering the leftover bits of the Nvidia driver (which I need for CUDA) that keep breaking electron/chromium is making me pull my hair out. I still hold my breath opening VSCode, wondering if its going to freeze or not.

That doesn't sound normal, even for Linux. It almost sounds like the issue is somewhere else. My first guess would be a PSU that's unable to source the 3090's current draw under load, given everything else running on your system.

Try using a dedicated rail or another PSU if you have one.

Its definitely not. I have a V850 SFX Gold, a single 3090 FTW3 and a 7800X3D, and its rock solid in OCCT's variable load test, even when overclocked (and its not overclocked on linux).

I have literally all the exact same issues on my RTX 2060 Asus G14 laptop, like:

- GPU rendering broken in Wayland Chromium/Electron, and sometimes Firefox

- Occasional black screen on boot, from some kind of race condition.

- Unpredictable artifacting on the KDE desktop and some apps.

And I still get some of that when Nvidia DRM is disabled and I'm just using the 4900HS/7800X3D for display out. Completely disabling the Nvidia GPU fixes all of it, every single thing, but then I can't use CUDA.

Problems like these is one of the reason I run windows and WSL2...
Also the reason why I got AMD when upgrading my graphics card.
I'd like to do that too, but currently you have to pick between games and AI stuff, at least on Linux. I'd love to support AMD on this, but their CUDA story isn't great.
True, but I considered a bit my needs and concluded that smooth Linux support is much more important for me than AI. My work doesn't directly touch AI, so for my modest AI needs I can just use online services that probably do it better anyway.
