I love my Ubuntu laptop, but I powered it down one day, and when I turned it back on I was met with just a black screen with a cursor visible in the bottom right part of the screen. It does not respond to any key inputs.
I read on Ubuntu 20.04 boots to black screen with flashing cursor that I should be trying to use the CLI, but I have no way of doing anything except going into bios. I ran Lenovo diagnostics, and it passed every test. I also read online that I could try a bootable USB to access my files and copy them to another USB to save them if I needed to reinstall the OS later. That did not work either due to permission issues.
After many frustrated attempts and nothing working, I installed Ubuntu on another partition of the drive. After doing this I referred to Ubuntu 22.04 boots to a black screen with a visible cursor, where I edited /etc/gdm3/custom.conf of my original partition with no luck. When I try and boot into it again, I am met with some glitchy login screen where I can just see my profile pic. From there I tried all combinations of CTRL+Shift+F# keys with no change except a few flickers of the screen.
I am truly at a loss for what to do. I spent a lot of time configuring my profile to be exactly how I wanted it. Now, I can see all my work sitting there without being able to use it. I do not like the GUI of Ubuntu 22.04.1 installation, and I would just like to get my old profile back.
I am open to trying anything to get my previous installation to work. I am a student, and a lot of my profiles for school work are still on there. I would prefer not to move everything over and start from there, because I miss the old GUI.
UPDATE:
After booting and selecting Advanced options for Ubuntu 22.04.5 LTS (on /dev/nvme0n1p3) and selecting: Ubuntu, with Linux 6.8.0-47-generic, I was able to use my laptop normally, but selecting Ubuntu, with Linux 6.8.0-47-generic results in a black screen.
Can someone please help me make this happen automatically so I do not have to navigate to that every time I want to use my laptop? I would also appreciate instructions on how to remove the recently installed Ubuntu partition safely.
