Public bug reported:

Yesterday, July 8, 2026, while I was using my computer the display got
weird.  Everything got larger, large enough not to fit on the screen
sometimes.

My computer is a Lenovo ThinkPad P16 Gen2, with an NVidia RTX-3500 GPU.  My 
System is Kubuntu 24.04.4 LTS
I also have a BenQ RD240Q external monitor that I plug into the laptop with an 
HDMI cable.

Release:        24.04

On the previous day, I had accepted a group of updates that had been
pushed to me by the Kubuntu notifier.

These included the following (taken from /var/log/apt/history.log):

Also included in the pushed upgrade notification were two firmware
update packages from Lenovo.  I have no record of what these were,
unfortunately. I accepted these as well.

These updates went smoothly and things seemed working normally until the
next day, July 8, when suddenly, the resolution on the screen blew
everything up to a larger size. When this happened I was using the
computer in not very video-intensive ways.  Web browsing.  Writing a
simple python script for my own use (non-graphic). The system went crazy
right before my eyes!

Notably, when moving the mouse, this not only moved the cursor, but also
caused the windows on the screen to move in the opposite direction, a
very disconcerting phenomenon!  Sometimes the windows are too big to fit
on screen and can't easily be closed.

Here are a couple of screenshots that I have saved on Google Drive that should 
be accessible to you:
when only one monitor is connected: 
https://drive.google.com/file/d/1xX8NIiODacryISUKAPN1HC3Ai7D3lero/view
and
when two monitors are connected: 
https://drive.google.com/file/d/1Jk6G02gsNL5Vod4P-cWLh7qRQESEewz5/view

I have tried the following things to resolve this
1. Rebooting
2. Stopping and restarting system
3. Uninstalling the existing NVidia driver and installing a new one, and 
rebooting again.  In the past this has been a useful thing to with monitor 
weirdness.
4. Attempting to change monitor resolutions in Kubuntu's System Settings --> 
Display and Monitor tab.
5. Stopping computer, unplugging external monitor, turning it back on.
6. Trying a number of different NVidia drivers and rebooting
  a. nvidia-driver-595-open (recommended driver)
  b. nvidia-driver-580-open
  c. xserver-xorg-video-nouveau
  d. nvidia-driver-595

None of these made any difference!

Originally, I had thought that the second monitor was somehow to blame,
but as #5 shows, the same pattern persisted without the external
monitor.  In fact the only way to get the system to be even minimally
usable is with the second monitor.  Then, windows exceeding the width of
the built in screen can be moved onto the external screen.

As #6 shows, changing nvidia drivers had no effect and even the non-
nvidia Nouveau driver exhibits the problem.

I am forced to conclude, then, that the problem must lie with the xorg
packages that were installed or possibly with the Lenovo firmware
upgrades that were done at the same time.  I don't understand why the
problem did not appear until a day later, but that still seems the most
likely assumption to me.

  Originally, I had thought that the second monitor was somehow to blame,
  but as #5 shows, the same pattern persisted without the external
  monitor.  In fact the only way to get the system to be even minimally
  usable is with the second monitor.  Then, windows exceeding the width of
  the built in screen can be moved onto the external screen.
  
  As #6 shows, changing nvidia drivers had no effect and even the non-
  nvidia Nouveau driver exhibits the problem.
  
  I am forced to conclude, then, that the problem must lie with the xorg
  packages that were installed or possibly with the Lenovo firmware
  upgrades that were done at the same time.  I don't understand why the
  problem did not appear until a day later, but that still seems the most
  likely assumption to me.
