Dell Latitude E6410, BIOS A03

Linux version 2.6.35-20-generic (buildd@berkelium) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #29~lucid1-Ubuntu SMP Tue Sep 7 13:27:10 UTC 2010 (Ubuntu 2.6.35-20.29~lucid1-generic 2.6.35.4)

As per #141, no X graphics on internal panel.

Fn+F8 to switch displays doesn't effect any control over which display is active.
External monitor is detected (but only if plugged in during Linux boot) & X display present on that monitor.
Menu -> System -> Preferences -> Monitors exhibits inconsistent behaviour. After previous reboot it did detect both displays & it was poss to turn "Seiko" panel display on/off - NB only backlight evident. Left panel in off state, power-down, booted again - only external monitor found. Internal not found and backlight off.
