Older Nvidia GPU not working under Kubuntu 26.04 / Plasma 6.6 (piefed.social)

I have an older gaming PC that has an Nvidia GTX 1060. Until I updated it to Kubuntu 26.04 and Plasma 6.6 it was working perfectly. Not exactly a powerhouse, for sure, but decent enough to play games like Horizon Zero Dawn at medium settings.

Since I've upgraded, it's now in a situation where if the GPU is active, there's no display, or I can use software rendering to get into the desktop, but the GPU can't do anything. But not both. If I can get to the desktop and search journalctl for kwin_wayland_wrapper, I get an error along these lines:

kwin\_wayland\_wrapper\[2921]: kwin\_scene\_opengl: Error during eglInitialize  "EGL\_NOT\_INITIALIZED"

The Nvidia driver is 580.142, which I've tried to roll back to a previous one to test if that'll work, but apt tells me that 580 is literally the only driver available. I have also completely purged and reinstalled the driver, just in case it hadn't installed properly, but that didn't help.

Is it fair to say that my GPU is pretty much dead under the new drivers? And if so, will I have to reinstall, either with a previous version of Kubuntu, or more likely switch it across to Arch?

Sorry if there's any info I've not included, I've kinda been picking about the internet, trying to figure out what's gone wrong with it, and don't really know where to start.

Try Nouveau, like Brickfrog said, if only to test the gpu.

I dont know if its the same but in Mint the Synaptic Package manager shows me all the versions of the nvidia driver supported by the kernel. Maybe you can downgrade your driver with it, although, I dont know how would you do that. Im just guessing but I think you would need to switch the transitional packages and those pull all the packages related to the driver.

Also, I've read a few times that distro upgrades can have weird problems and clean installs are better.
