Thread: External monitor resolution

i got 2 hard disks macbook 4,1.

1 has refit + leopard + ubuntustudio10.04 kind of installation: http://www.rodsbooks.com/ubuntu-efi/index.html

other has ubuntustudio 11.10 automatic installation.

on ubuntu 10.04 can see exact resolution 1360x768, while on ubuntu 11.10 can see 1024x768 resolution.

happen because ubuntu 11.10 doesn't read informations leopard efi?
