[SOLVED] Problems with screen resolutions about hertz

Hello everyone, I have a problem with the resolution configuration of my screen, this happens to me in any desktop environment other than gnome and this also happens to me even if I am using X11 or Wayland. The specific problem is that my screen supports up to 144hz refresh rate tested at the hardware level but when I try to make that change in , in this case, using kde plasma. Something similar happens in Wayland, when I try to make the change the entire screen breaks. I have tried to diagnose on my own what the problem may be, however I have not been able to find a solution.

As I emphasize, this does not happen with gnome, it only happens with any other desktop environment. I'm going to upload a couple of videos that show the error so that it can be seen correctly.

Re: [SOLVED] Problems with screen resolutions about hertz

Recap of the videos: glxgears on compositing plasma/X11 reflects kscreen modeline changes (confirmed by xrandr) between 60Hz and 120Hz but changes to 144Hz (confirmed by xrandr) are inert and glxgears renders at the preovious rate.
Trying to set the 144Hz mode on plasma/wayland has causes massive visual corruption.

For plasma/X11 try to suspend the compositor (SHIFT+Alt+F12) - is the output https://wiki.archlinux.org/title/Variable_refresh_rate capable?

Since it's a hybrid system, do all environments run on the same GPU?
("glxinfo -B" should suffice)
Did you test gnome on X11 (as well) or (only) gnome on wayland?

Edit: Please use [code][/code] tags. Edit your post in this regard.

Hello, suspending compositor does not fix the issue.

Re: [SOLVED] Problems with screen resolutions about hertz

Possibly not.
https://wiki.archlinux.org/title/Variab … rate#GNOME

vrr_capable: 1

Check your xorg log whether "VariableRefresh" is mentioned,  https://wiki.archlinux.org/title/Xorg#General
Disabling VRR in KDE will likely get you similar behavior as in gnome - whether that's desirable is a different matter.
Well, it probably would be in the wayland context where this is apparently buggy?

Ok, I understand. I checked my X11 configuration and watch this:

❯ cat /etc/X11/xorg.conf.d/20-amdgpu.conf
Section "OutputClass"
     Identifier "AMD"
     MatchDriver "amdgpu"
     Driver "amdgpu"
     Option "TearFree" "true"
     Option "VariableRefresh" "false"
     Option "EnablePageFlip" "on"
EndSection

and check my X11 log and say Vrr is turn off.

❯ cat /var/log/Xorg.0.log | grep Variable
[     9.595] (**) AMDGPU(0): Option "VariableRefresh" "false"
[     9.771] (**) AMDGPU(0): VariableRefresh: disabled

But after a reboot I check newly xrandr but still says vrr_capable = 1

❯ xrandr --props

Re: [SOLVED] Problems with screen resolutions about hertz

But after a reboot I check newly xrandr but still says vrr_capable = 1

That will probably reflect only the output, not the driver.
Did you test the glxgears (on plasma/X11) behavior after disabling it in the driver?

Yes, I did. The behavior is the same. Same problem.

Re: [SOLVED] Problems with screen resolutions about hertz

Same if you run

adaptive_sync=false glxgears

To test whether this generally works,

vblank_mode=0 glxgears

should get you completely unsynced, maximum FPS glxgears

Hello, the code adaptive_sync=false does not show any difference.

With vblank_mode=0 the FPS are incredible hight but does not fix my problem.

Re: [SOLVED] Problems with screen resolutions about hertz

Well, I upgraded my kernel to 6.9 from core-testing and fix my issue with X11, later I will to test with wayland.

Edit:

Wayland fixed. With 6.9 kernel every problem has been fixed.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

FPS are incredible hight but does not fix my problem

For clarification, was there a (visual?) problem beyond glxinfo not stepping up to 144Hz? (This would of course not happen since glxgears ran completely unsynced)

In that case, glxgears exceeded 144hz, it went up to 95625625 fps. xd

Ok, I'm marking the thread as resolved.

Thanks for the valuable help, if you didn't tell me what it could be the variable refresh rate I wouldn't be able to locate the AMD bug. My God, AMD had us with a bug for 6 months and then we are demonizing Nvidia.
