After updating today the system and the Kernel I can no longer run any games on my optimus enabled Nvidia graphics card. The game either stops or the system freezes completely.
It used to work fine before the update and I can also still run games on the intel gpu.
Probably Nvidia driver and Kernel 5.12 related, but I’ll test a few things.
Running kernel 5.12 with the latest nvidia drivers on testing branch, I’ve not really gamed since the update but just fired up Just cause 3 in steam and it was playing fine
With Nvidia Optimus? It really looks like a Prime issue to me.
Edit: hmm, downgrading to Kernel 5.11 by deinstalling & rebooting initially didn’t fix it, but a full hard freeze and a reset later it seems to work with Kernel 5.11 now.
