I haven’t tested X11 yet but I can reproduce this on NVIDIA 560.31.02 even by overriding the stock EDID with itself.
Tested on Fedora Rawhide, GNOME 47~beta
Hi @adolfotregosa@mattiaformichetti
Thanks for reporting issue to us, I have filed a bug 4797139 internally for tracking purpose.
Also, could you please confirm if there was any last passing driver.
I remember trying to alter my monitor’s VRR range in the past to decrease some flickering issues that might be related to a problematic LFC implementation; While I still have to report that properly I’m almost certain that this isn’t a recent regression.
I could retest older drivers if needed, in which case please suggest relevant versions, but, as far as I can remember, it didn’t work in the 555 branch and, potentially, 550.
The original discussion started in the GNOME Shell Matrix chat on the 10th of June so it’s likely that I was using one of the 555 drivers.
I can confirm the same behavior but for me it happens only on one of the two monitors but I do it in a different way (using the kernel switches). This started happening on 555. On 550 both monitors were showing VRR capable when EDID was passed like that. Now only the DP-2 shows as capable.
Interesting, I remember trying that at the time and it wasn’t working either.
Also, I only have DP 1.2 to test, my other monitor is HDMI 2.0 and, as far as I know, only AMD supports VRR on 2.0.
Is there any feedback from engineering regarding this issue?
It would be great to have this fixed, specially since we now finally have working multi-monitor VRR in driver 570. But that completely goes to waste if we need to override the EDID in one of our monitors, due to this bug completely disabling VRR.
Just tried it, no VRR on 570.86.16 (DisplayPort).
The new driver also broke HDMI 2.1 VRR with or without custom EDID, so we’re worse than before. Great.
I came here, because I installed the 570 driver on my Arch system (KDE).
Because the VRR range of my BenQ EX3203R is not the best, I edited the boot parameters to load a custom edid. After rebooting, the Adaptive Sync option in KDE is gone.
