Hello all. I have the same issue with the following settings:
NVIDIA GeForce RTX 4080 GPU/PCIe/SSE2
Graphic Platform X11
DP-0 connected primary 2560x1600+0+0 (normal left inverted right x axis y axis) 344mm x 215mm
The hardware is a Lenovo Legion Pro 7 16IRX8H laptop running Ubuntu 23.04.
With the 515 driver series, this was not occurring. I’ve noticed that flickering appears only on top of the screen.
PS, it started appearing with 535.x series (even on previous beta drivers)
After fresh install of Fedora 38 everything was ok with default drivers…after installing both first NVIDIA 530, and then, 535 there was a random flicker in the top of the screen…in the game i didnt notice it though…i assume that it has to do with Xorg11 and wayland windowing system,i also use G-sync dell monitor with 165 hz refresh rate…ill put my whole hardware config here for more details just in case.
Comically my flicker is no longer at the top of the screen but seems to rip through the middle. (Slow Clap) Good Jorb! I will note it’s a lot less frequent though. It used to happen fairly consistently every few minutes but now I just catch maybe 2 or 3 a day…but it’s still happening. The fact it’s “lower” on the screen does suggest some whacky timing issue though.
As a side note (for me at least) I noticed for well over a year the nVidia settings panel never correctly loads my settings which in theory can imply any timings I’ve set are constantly “lost” and things just go back to possibly bad defaults.
I was facing this issue even on 535.98 using the nvidia-dkms package while using 6.1.46-1-lts kernel on arch linux. But that changed when I switched to nvidia-lts package instead. Now I almost get no flickers. Very rarely I see like a few flickers on the top portion of my screen, still running my monitor at 2560x1440 @ 144Hz refresh rate.
It’d be great if someone else can confirm if this is a one-off or a reproducible observation. Thanks.
Unfortunately there are a few glaring issues I’ve had with my nVidia cards with no mention of if they will ever be fixed. This is iirc 4 driver updates with the flicker. The fact they think it’s fixed in the latest release gives me little assurance any of the issues I’ve open will be addressed. At this rate it’s a sad possibility waiting for the open source drivers might be the only hope anything gets done…which could still be years off. This should be part of the marketing. Bad prices, underwhelming performance and stranding customers with broken drivers…nVidia, it’s how it’s disma(pla)yed. /rant
Mine are saved in the config but the nVidia settings can’t load via the syntax it saved. Seems like the now too common stupidity where the settings panel understands to save correctly based on which GPU has what set but the load portion has had the GPU denotation bit removed causing all settings for all GPU’s to just be ignored and “default.”
Just bought Lenovo Legion Pro 5, with NVIDIA 4060. On Ubuntu, with Ubuntu automatically selected version of gpu drivers, I am sometimes getting flickering of the upper part of display, primarily when I watch video or YT. After reading this thread, I am only glad that it seems not a hardware issue:)
I use --load-config-only but the settings do not understand their own syntax. This is a growing issue where multi XScreen “remnants” remain while their functionality is broken because no one is paying attention to them anymore (assuming they are dead or unused.) This is all GTK/Wayland’s doing but the end result is I can save things but then it doesn’t comprehend how to load what it saved because the syntax is broken.
So when I save the syntax is “hostname:XScreen/setting” but when you load the loading process has no clue what the XScreen portion is and tosses errors.
It’s might also be worth noting the inconsistency in the settings. In some places hostname:XScreen/setting in others GPU:#/setting and in others yet still GPU_#.
