Garbage displayed when booting Ubuntu 22.04 LTS

[Kevin Lopez]

What I expect to happen:
The system to boot and not give me garbage on screen

Whats happening:
I am getting garbage on screen when I boot a freshly installed ubuntu 22.04. Some things I noticed:
When plugging in either a usb c monitor or a thunderbolt 3 docking station that has monitors attached, the garbage goes away and I can use the computer normally regardless if the external display is connected after the initial connection.

If I leave the machine alone for about 5 min (enough time for the screen to "turn off" after inactivity) it will suddenly work as intended without having to connect an external monitor.

if I boot the machine in recovery mode (using grub, advanced, linux-xxx (recovery)) then just hit start normally it will let me in (but external monitors don't seem to work)

If I set the kernel flag to i915.modeset=0 It lets me boot, but I get no splash screen and external monitors dont seem to work

I have tried several different kernel options such as:

GRUB Param `i915.enable_psr=0` did not fix
`intel_idle.max_cstate=4` did not fix
`intel_idle.max_cstate=0`did not fix

from here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1970426

I think this is a different bug from the link above, but similar as it involves the same graphics.

I also tried installing different kernels such as 5.17, 5.17.7 5.18, and the latest non RC mainline kernel.

I tried enabling and disabling secure boot, nothing...

This laptop worked fine until I upgraded to 22.04 (I upgraded but it gave this screen corruption so I did a fresh install). The only kernel that seems to work is 5.13.x. It gives no errors, and I can see the splash screen.

My issue is exactly like this:
https://www.reddit.com/r/Ubuntu/comments/usckph/ubuntu_2204_upgrade_gone_bad/i92wpi4/

Screen flashes, some parts are purple, sometimes it turns grey or black, and this happens before we get to GDM as my drive is encrypted and it happens by that point too.

I don't know what else to do as everything I throw at it seems to not work. Seemingly the only workaround is to downgrade the kernel to one that is not even on the jammy repos. I would appreciate any help with this issue.
