I installed a new used gpu (Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280]). It froze on boot and I used grub recovery mode to try and fiddle with the drivers from amd. I found this command which supposedly installs all the possible amd gpu drivers:
sudo apt-get install git && git clone git:// && sudo cp -v -u linux-firmware/amdgpu/* /lib/firmware/amdgpu && sudo update-initramfs -uk all
After this I tried rebooting which got me to the point where I had access to TTY. This is the sudo journalctl -p 3 -xb output

The output to
cat /etc/udev/rules.d/70-amdgpu.rules
Is:
KERNEL=="kfd", GROUP=="video", MODE="0660"
After trying to remove the udev rule that causes the error i get this:

Here are my system specs.
OS:Ubuntu 20.04.2 LTS x86_64

Some additional info that might be pertinent:
-Ksplashqml crashes every time I log in to the desktop environment and if I click restart the application the desktop environment crashes and I'm back to TTY.
-Every time I close out of Konsole it says that Konsole has closed unexpectedly. A few other programs do this but not all of them. Firefox doesn't do this for some reason.
-Both of my monitors display the same output. Xrandr gives me this
xrandr: Failed to get size of gamma for output default Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080 default connected primary 1920x1080+0+0 0mm x 0mm 1920x1080 77.00* 1 Answer
Found this post regarding that.
Seems like there is one too many == in GROUP=="video", I've changed mine to GROUP="video" and the "Invalid Opearator for GROUP" error desapears.
