Bug Description

I changed monitor from 24" LG to 32" Samsung LS32A704NWPXEN

The situation looks like this:
1. 4K starts default, I can save settings to /etc/X11/xorg.conf only with
sudo chmod u+x /usr/share/screen-resolution-extra/nvidia-polkit

2. Problem I have with HDMI and DisplayPort, the situation is the same,
 after changing from 1920x1080 to 4K I can see 1/4 of the screen
lower left part of the screen.

The problem does not occur from 4K to 1920x1080 when 4K is default.

To switch to 4K I need remove /etc/X11/xorg.conf and reboot system.

3. Scaling in Mate does not change the size of the Steam icon xD wtf? Why?
I have only option 100% and 200%.

4. Scaling with Nvidia, ( Option Underscan in second tab of nvidia-settings, default is 0 )
I managed to check by placing the panel at the top and then changing the scaling in nvidia
(because the image is cut off from the bottom)
It seems to me that this option does not scale, but crops the image.
Because the font and icon sizes looks identical.
Only the picture frame is cut off and the center remains.

5. This monitor does not have an image scaling option.

At the present day
- I upgraded driver to nvidia-driver-535 , 535.113.01-0ubuntu0.22.04.1
- I installed xserver-xorg-dev to remove above error about `xorg-server.pc'
But when I'm trying save settings to /etc/X11/xorg.conf
I have warning:

========={

- After reboot I have 4K instead 1920x1080
- I checked whether the changes had actually been saved.

I did
- removed /etc/X11/xorg.conf
- checked with ls and not exist file /etc/X11/xorg.conf
- saved settings to /etc/X11/xorg.conf
and file exist
- after reboot, in /var/log/Xorg.0.log I see

Do these programs use a different configuration file?
