nvidia on a HP Pavilion tx1000 laptop - corrupt graphics

[Ian Bruntlett]

Screen gets corrupted.

The GNOME time at the top of the screen tends to get corrupted - it looks like the graphics are being logically "OR"ed onto the existing frame buffer.

On one occasion, the entire wallpaper was corrupted.

In other occasions, the system menu contents are partly corrupted.

This shows screen corruption where there are two mouse pointers.

This is a screenshot of the wallpaper being corrupted (does not happen often)

This also happens on Ubuntu 22.04 beta (x86_64). I have a workaround which appears to overcome the graphics corruption problems on this system...

Using information gleaned from:-
https://linuxconfig.org/how-to-disable-blacklist-nouveau-nvidia-driver-on-ubuntu-20-04-focal-fossa-linux

I performed these commands:-
sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"

sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"

And ensured that /etc/modprobe.d/blacklist-nvidia-nouveau.conf contained the right informaiton:-
cat /etc/modprobe.d/blacklist-nvidia-nouveau.conf

And the file should contain:-
blacklist nouveau
options nouveau modeset=0

Then this command is used to finish things off.
sudo update-initramfs -u

Then I rebooted and the graphics corruption appears to be eliminated.
