I know NVIDIA on Linux is somewhat bad, but this bug has been driving me insane, and it is still not fix as of 535.104.05 my screen flicker even more than the last driver update
I hope this get fix in 540 drivers updates or later, but I’m getting an AMD GPU when I get to build my PC very soon.
I had it come back after the 535 drivers dropped for my 1660 super. Was lucky that downgrading back the previous version took it away.
From what I read it introduced the flickering for a bunch of other cards too.
It got fixed in the windows driver for the 1660 freakin ages ago but only recently on Linux before the reintroduced the issue recently. Changing the power mode never did anything for me.
I had the same situation and solution with my 1660ti. I thought there was something wrong with my monitor for a bit because it didn’t show up on the second screen.
