Can't get my monitor to work at 144hz

Hi, I just installed Manjaro and I’m struggling to get my main monitor to work at 1440p 144hz. Here’s my xrandr -q output:

As you can see, I tried to create custom resolutions using gtf and cvt but adding either of them using xrandr results in this error:

I also found this line in /var/log/Xorg.0.log:

[ 4396.038] (--) NVIDIA(GPU-0): Ancor Communications Inc ASUS VS228 (DFP-4): 1440.0 MHz maximum pixel clock

The monitor it mentions here is actually my 60hz 1080p monitor, I don’t know if this contributes to the problem. The “corresponding” line for the 1440p144hz monitor looks like this:

[ 4302.028] (--) NVIDIA(GPU-0): Acer XF270HU (DFP-0): 330.0 MHz maximum pixel clock

I did some research already but I couldn’t find anything that fixed my issue, maybe some of you know what’s wrong… Thanks in advance!

Install edid-decode and then post the output of

echo -n /sys/class/drm/card*-* | xargs -d ' ' -I {} -exec bash -c 'edid-decode {}/edid ; true'

.

One thing you could try is removing (back up) all video related Xorg configuration (xorg.conf, 90-mhwd.conf, etc.), then reboot, and see if the automatic configuration works better.

Thanks for your reply, here’s the requested output:

$ echo -n /sys/class/drm/card*-* | xargs -d ' ' -I {} -exec bash -c 'edid-decode {}/edid ; true'    
xargs: warning: the -E option has no effect if -0 or -d is used.

/sys/class/drm/card*-*/edid: No such file or directory

Removing the config files did not make a difference either…

Do you have two video cards? Can you attach the output of inxi -Gazy and xrandr --listproviders?

xrandr still only shows 60 Hz?

Post the output of head -n999 /etc/X11/xorg.conf.d/* /etc/X11/xorg.conf as well.

Yes, xrandr showed the same set of resolutions and refresh rates.

I only have one GPU installed at the moment and no CPU-driven graphic chip.

6

Have you created the mode with xrandr --newmode?

7

Yes, you can see the 2 modes I created in the first post.

8

Ahh, indeed, I missed them. Is there anything in the Xorg log after you run the addmode command?

9

No, nothing in the logs. Today I tested everything on 2 different live systems (Ubuntu, Manjaro) and the open source drivers were in both cases capable of doing 144hz while the proprietary nvidia ones weren’t. Maybe I should try another nvidia driver version; open source drivers aren’t an option because of their performance deficits.

10

My guess is that this may have something to do with the nvidia Xorg video driver. It could be confirmed, but not very easily. Can you post the output of lsmod | grep nvidia?

11

Here you go:

$ lsmod | grep nvidia
nvidia_drm             69632  5
nvidia_modeset       1232896  16 nvidia_drm
drm_kms_helper        278528  1 nvidia_drm
drm                   569344  8 drm_kms_helper,nvidia_drm
nvidia              34172928  1003 nvidia_modeset

These are the two modelines I’m testing with by the way:

Modeline "2560x1440_144.0" 580.080 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync
Modeline "1920x1080_144.0" 335.770 1920 1968 2000 2080 1080 1083 1088 1121 +hsync -vsync
12

And none of the work, I assume?

Can you run sudo systool -vm nvidia_drm | grep modeset and post the output?

13

And none of the work, I assume?

No, both resulting in the same error.

$ sudo systool -vm nvidia_drm | grep modeset
    modeset             = "N"
14

Please try the following:

sudo systemctl isolate multi-user
sudo rmmod nvidia_drm
sudo rmmod nvidia_modeset
sudo modprobe nvidia_modeset
sudo modprobe nvidia_drm modeset=1
sudo systemctl isolate graphical

then run

echo -n /sys/class/drm/card*-* | xargs -d ' ' -I {} -exec bash -c 'edid-decode {}/edid ; true'

.

Note, that this will close and restart your graphical session, and thus all applications running within.

Interesting, no 144 Hz mode is in the EDID. I think that could be why the nvidia Xorg driver might reject the 144 Hz mode.

Can you run

echo -n /sys/class/drm/card*-* | xargs -d ' ' -I {} -exec bash -c 'edid-decode {}/edid ; true'

and

xrandr -q

when 144 Hz is working and post the output?

Have you tried having just a single monitor connected?

The nvidia X driver has “ModeValidation” option… maybe that could do something:

Option "ModeValidation" "NoHorizSyncCheck, NoVertSyncCheck, AllowNonEdidModes"
17

Both commands were run in a live Manjaro environment with open source drivers and 144hz enabled:

$ echo -n /sys/class/drm/card*-* | xargs -d ' ' -I {} -exec bash -c 'edid-decode {}/edid ; true'
xargs: warning: the -E option has no effect if -0 or -d is used.

The ModeValidation didn’t make a difference either. I also to tried overriding the EDID using CustomEDID with one extracted from my Windows installation and another one from a livesystem, both to no avail.

That’s unfortunate. There’s also UseEdid and UseEdidFreqs options that you could try.

Maybe give these ones a try (genrated with cvt 1.2):

Modeline "2560x1440_144.00_rb1"  604.25  2560 2608 2640 2720  1440 1443 1448 1543 +hsync -vsync
Modeline "2560x1440_144.00_rb2"  586.59  2560 2568 2600 2640  1440 1529 1537 1543 +hsync -vsync

There’s also UseEdid and UseEdidFreqs options that you could try.

Using either of them, xrandr --addmode still fails with the same error.

Maybe give these ones a try (genrated with cvt 1.2)

Still a BadMatch, think it’s independent of the modeline.
