Dell Latitude E6410

After upgrading to kernel version 3.0.0-15 via the Update Manager and rebooting, the laptop display was blank (after grub).

If connected to an external monitor via a Dell docking station, the external monitor displays correctly, but the laptop display remains blank.

Tried disabling and re-enabling the display via Unity System Settings, but the problem persists.

The display works correctly if I reboot to kernel 3.0.0-14.
