Screen turns yellow even using the live option Ubuntu 22.04

I've already performed the tests and changed the cable. I've come to the conclusion that it's not a problem with the cables or the monitors because I tested it with other distros even in Windows and the image is normal. I believe it's a problem with Wayland with the Nvidia video card, as my GPU is a GTX Nvidia GeForce 1650 Super.

It appears this is a reality. I was fine the other day before upgrading to 22.04 and now, my secondary display (my TV) has a yellow tint like it's stuck on Night Light mode. I've tried everything I can think of and I cannot fix the issue. I have also come to the same conclusion as you

UPDATE: It seems that the profile might be getting corrupted somehow? I removed the profile that was automatically assigned and set the RGB profile to D65 and everything seems fine again. I also tried a few others in the list and they seemed to be OK. Give it a whirl and it will likely solve your problem.

I fixed it.

I was using nouveau, part of mesa, the default open source nvidia driver.

Somehow the windowing system switched from wayland to x11 and then I got yellow screen(1st screen) and red screed(2nd screen).

I reinstalled mesa related pkg.

sudo apt autoremove mesa*
sudo apt install mesa*

Then I

sudo nano /etc/gdm3/custom.conf

Set WaylandEnable=false to true

WaylandEnable=true

Then restart gdm3

sudo systemctl restart gdm3

I don't know when it switched to x11, but x11 doesn't seem to be working well with nouveau on ubuntu 22.
