I’m hoping someone can point me in the right direction because I’m running out of ideas.
I’m running Fedora 43 with KDE Plasma. My monitor is a Acer SA242Y Monitor which supports up to 100Hz.
Up until recently, everything was running perfectly at 100Hz. Now, the Display Configuration settings in KDE only show 60Hz as the maximum available refresh rate. I can’t seem to force it any higher even withxrandr.
My Desktop Setup:
OS: Fedora Linux 43 (KDE Plasma Desktop Edition) x86_64
Host: AMD
Kernel: Linux 6.17.7-300.fc43.x86_64
Display (SA242Y): 1920x1080 @ 60 Hz in 24" [External]
DE: KDE Plasma 6.5.2
WM: KWin (Wayland)
CPU: AMD Ryzen 5 5600G (12) @ 4.46 GHz
GPU: NVIDIA GeForce RTX 3060 [Discrete]
Memory: 40GB
This is what I have tried so far.
Completely reinstalled the NVIDIA drivers
Tried manually adding a new modeline/resolution for 100Hz with xrandr, but it show up
Checked the cable connections with hdmi and DP
Since it was working correctly before, I assume an update might have broken something, or a config file got corrupted.
Has anyone experienced this recently or know which logs I should be looking at to diagnose why it’s not showing the higher refresh rate on my monitor?
Could be the bug discussed in this thread with the 580.105 drivers?
That thread is about resolution issues, rather than refresh rates, but I noticed that someone on the linked Github ticket said they had refresh rate problems.
Can confirm the latest driver also affects refresh rates. Installed the latest drivers(580.105.08), and my 1920x1080/100hz monitor could not exceed 60 Hz at all, even xrandr/kscreen doctor thought it was a 60hz monitor. Downgrading to the same drivers darklenre was on previously(580.95.05) is now allowing my monitor to run on 100hz without issue again.
