I restarted my computer and on the next boot I noticed the login screen was extremely zoomed in. When just on the desktop I can pan left to right now which wasn't something I did before and is needed just to get to various parts of the desktop. I tried exploring the settings and found it is reporting a Built-in display and an "Unknown Display" now. This made me believe it wasn't recognizing my original laptop display and I ran "xrandr --query".

The outputs of xrandr --query

Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm panning 3840x1080+0+0
   1920x1080    144.00*+
None-1-1 connected (normal left inverted right x axis y axis)
   1920x1080     60.00 +

Which shows There are two displays Screen Zero and None-1-1. My built-in display is 1920x1080 144 refresh rate not the 3840x1080 144 refresh rate or the 1920x1080 with 60 refresh rate.

I looked in the logs to see if there was any indication of what was happening and found multiple entries that are

[drm:nv_drm_master_set [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to grab modeset ownership

I also found these logs as well

I'm just not sure how this started to begin with or how to fix this. I made sure my system was up to date. Please Help!

UPDATES

I learned that using this command

systemctl restart gdm

it restarts the driver and the resolution is corrected but upon a full system (turning on and off) restart it reverts back to the problem.

I found a solution to my problem using the information here. Apparently this is a common issue for NVIDIA devices udating to ubuntu 24.04 and this is the work around.

Use this command:

sudo gedit /etc/X11/xorg.conf.d/10-monitor.conf

This is creating a config file that will run and add this to it:

Section "Monitor"
    Identifier "None-1-1"
    Option "Ignore" "true"
EndSection

Where "None-1-1" is your phantom device name. Mine was as listed here. This config will ignore this monitor from setting up and thus xscreen zero only has one display listed in it.
