I tried editing /etc/X11/xorg.conf as detailed here: Brightness not working after installing NVIDIA driver

My Ubuntu MATE installation on my MacBook Pro Mid-2010 13" now gets stuck at the "UbuntuMATE" boot screen. It just freezes there.

My graphics card is an NVIDIA GeForce 320M.

  • @Pabi Would Ubuntu's Recovery Mode do the job? – arcetera May 1 '15 at 0:39
  • Yes you can enter a root shell from there and revert the changes you made. – Pabi May 1 '15 at 0:41

You can use grub to enter a root shell:
Press e when in grub and edit the line looking something like:
linux /boot/vmlinuz root=/dev/sda4 ro quiet splash to
linux /boot/vmlinuz root=/dev/sda4 ro single.

Alternatively you can use ubuntu recovery and launch a root shell from there.

Then just revert the changes you made to /etc/X11/xorg.conf and reboot.
