[SOLVED] Displays bugged after Syu update

Hi there, having a strange issue with displays not working as expected after a recent update.

I am using Xorg with xfce4. The issue is in the display or using xrandr, I cannot pick up any external HDMI monitors. Also the current laptop display is None-1, and stuck with the same resolution and there are no options in the refresh rate or resolution drop down.

So far I have tried changing to an LTS kernel and reinstalling different versions of nvidia drivers, but no luck. There must have been a recent update to something related to Xorg which has broken this.

xrandr now outputs:

None-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1920x1080     60.00*+

Previously I'd have HDMI-1 and the usual laptop display.

Looking in the Xorg.0.log file, I can't see anything too obvious. I do see repeated a lot:

[685773.231] (--) modeset(0): HDMI max TMDS frequency 225000KHz
[685773.231] (--) NVIDIA(GPU-0): DFP-0: disconnected

[685759.987] (II) NVIDIA(G0):     Config Options in the README.

Edit: also strangely enough the sensors bar cannot detect the temperature like it did before. I think this may hint where the problem is.

If anyone has any hints on how to resolve the issue it'd be greatly appreciated.

Thanks

Re: [SOLVED] Displays bugged after Syu update

That's the SIMPLYDUMB device, add "nvidia_drm.modeset=1" to the https://wiki.archlinux.org/title/Kernel_parameters (some modprobe.conf won't do!) and then please post your entire Xorg log, https://wiki.archlinux.org/title/Xorg#General

Thanks that seems to have helped.

Initially Xorg would refuse to start with connection refused, but after rebooting a couple of time it seemed to have come good. Thanks!
