Yester I asked this question, and tried to follow cl-netbox's advice:
Highlight the Ubuntu entry in the GRUB boot menu and press the
E
key. Addnouveau.modeset=0
to the end of the linux line - pressF10
to boot. On login screen pressCtrl
+Alt
+F1
... enter user name and password ... Now execute the commands ...
After pressing Ctrl
+Alt
+F1
at the login screen and writing sudo apt-get update
, the laptop asks me for my password (as per usual). However, the password that I normally always use does not work. I've no idea what password I should use. Anybody can help me?
