I might be suggesting heresy here so feel free to get your torches and pitchforks ready... but are you running a full wayland desktop or X11?
I ask for multiple reasons.. aside from kernel log messages, the actual errors you are encountering are mostly higher up in the stack. Top level applications like the window manager and firefox. X11 is a more mature platform. As much as people say it sucks it is battle tested and everyone knows what to expect from it. wayland on nvidia support has been iffy for a long time. I keep seeing claims that wayland is now on par with X11, but the reality is that there have been problems on wayland desktops that are nvidia specific. If you are able, try something like XFCE or KDE's plasma-x11 and see if any of these problems reproduce. The only real problem with nvidia's drivers is that they tend to have a NIH problem with the existing driver stack and often opt to roll out their own userspace components that conflict with DRM/KMS and mesa. X has the ability to handle this conflict, but wayland might be iffy. Note the nvidia-drm kernel module.. for amd/intel we just the regular drm module. This is important, because your processor has an AMD GPU built in. https://www.amd.com/en/products/processors/laptop/ryzen/ai-300-series/amd-ryzen-ai-9-hx-370.html There is a very real possibility that nvidia's driver and amdgpu are clashing which can result in applications falling back to software rendering on the CPU. It's entirely possible that each screen is being handled by a different driver result in pure userspace chaos. -Ben On Saturday, May 23rd, 2026 at 4:57 PM, Mark Phillips <[email protected]> wrote: > I have a brand new System76 Oryx Pro running Ubuntu 24.04 running on a > Ryzen™ AI 9 HX 370.
