Hi, everyone!
I installed Ubuntu on my iMac from 2011, and it will have a screen glitch where the screen splits up into four different sections. It is also very difficult to read and is rather pale. Due to this, I am having a very hard time navigating it and generally troubleshooting. When I go to a new installation and go to "Safe Graphics Mode", it is generally fine during the installation process. It is only after I have installed that and it restarts that it does this. It also does not have any issues for the first few seconds of booting. It lists the amount of clean files during this time.
Because of this issue, I cannot see any specific lines of code, so if I am to fix this (like turning on safe graphics mode all of the time) I need very, very, very clear instructions that do not require me to be able to see the text!
I will include a picture from my phone of what the screen looks like. It is very difficult to see even larger font sizes. I only got this far by watching videos and changing the resolution settings a lot.
P.S. I do have an SSD, not sure if that changes anything.
