Forced to upgrade to Fedora 36. Bug persists in F36 with the 520 (520.56.06) driver. I cannot seem to get 510 or 515 to compile with rpmfusion akmods on F36 so now I am stuck with the flickering 3rd monitor. I just turn it off now – it’s unusable with the screen blanking bug.
I can report that I ran F35 with the 515 driver for the 2 months since I reported this bug. As I said before 515 does not have this problem and my setup worked flawlessly the whole time. 520, no matter the OS/kernel version is faulty and has this bug.
I have found similar me-toos in the newer bug reports. To consolidate them, I note them here:
Maybe the 3 of us together can discover all the commonalities. There must be something unique to our setups because it’s clear most people do not have this problem. However, the problem is real, and it’s not a hardware problem as everyone has reported that they can fix the bug by using 515 or Windows.
