Running Ubuntu 18.04.02 LTS (Kubuntu) on a Macbook Pro (2013 or 2015 I think) and I am having an issue when I boot. It takes around 5 minutes to get to a black screen with only the mouse pointer visible. Ubuntu is the only OS I have installed and I don't recall changing or updating anything but everything was running fine one day and then the next day I booted I ran into this problem.
I can use Ctrl+Alt+F2 and get to the command line and start the desktop fine with the command "startx" but it is annoying to have to go through this process.
Does anyone have a way I could begin to troubleshoot this? Thank you!
