My computer is a Dell XPS laptop.
I was able to us my Ubuntu 19.04 installation without any problems, but today while working it started to act strange. Every command I would enter into the terminal resulted in permission denied. So I decided to reboot.
I would then enter the password to decrypt the partion, and then it would go to a blank screen, sometimes with a static _ in the upper left corner.
Things I tried
Changed
/etc/default/grubfromGRUB_CMDLINE_LINUX_DEFAULT="quiet splash"toGRUB_CMDLINE_LINUX_DEFAULT=""Tried purging nvidia, but nothing was removed, presumably because it wasn't installed.
So I tried to install the Nvidia graphics driver with
sudo apt install nvidia-driver-390. This slightly changed the result, but only slightly. Now the screen is almost blank, with the exception of a green OK in the corner. However, on subsequent reboots I now no longer get the green OK. I just get a static_.Output from

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.mybakbut get/etc/X11/xorg.conf no such file or directory.Tried
