I just converted ubuntu desktop 14.04 to ubuntu server using these steps:
sudo service lightdm stop sudo apt-get install tasksel sudo tasksel remove ubuntu-desktop sudo tasksel install server sudo apt-get update sudo apt-get install linux-server linux-image-server sudo apt-get purge lightdm sudo apt-get purge firefox sudo ifconfig eth0 up sudo dhclient eth0 sudo apt-get upgrade
Then I installed Sentora. When I rebooted at the end of that, I got a black screen for about one minute, then an underscore in the top left corner for a couple seconds and then the terminal started. I feel like there's something messed up in grub where it's still trying to start lightdm and that eventually times out and it goes to terminal. Does anyone know how I could check that and fix the issue?
