I'm trying to fix the “the system is running in low graphics mode” problem. When I press Ctrl+Alt+F1 to go to tty1 and login, it goes straight back to the login prompt. Why does this happen and how can I get to the terminal?
Running Ubuntu 14.04.5 on an Asus laptop with nvidia card.
EDIT: After i try to login it says unable to cd to '/home/user'
EDIT2:
$ namei -xl /home/*
f: /home/user
$Drw-rw-rw- root root /
$drwxr-xr-x root root home
$drwxr-xr-x user user user
EDIT3: Thanks for the time and help. I booted Ubuntu from usb and backed up important files and reinstalled Ubuntu. It appeared that all files were changed to root? All directories like: /home /opt were binary and inaccessible files. Only as root I could navigate the directories and copy them to a usb.
namei -xl /home/*and [edit] your question with the result – steeldriver Jun 10 '17 at 12:55
