I have installed ubuntu 16.04 LTS version using a bootable usb. It has given me a lot of grief.
Earlier it was not showing me the login screen, I resolved it by disabling secure boot option in the BIOS.
Now, the os is not restarting, whenever I click on restart it gets stuck. However, shutdown is working perfectly.
Following command doesn't work, the machine hangs after executing the command:
ctrl + alt + F1doesn't work on the login screen, it doesn't show me the console.
I cannot even
logoutfrom the system.
