Bug Description
Use of Fn-F8 key combination to switch to external display on Dell Latitude D620 under Ubuntu Dapper works for one 'cycle' only, then locks up the display.
Here's what happens, and it's repeatable -
Start with standard laptop display, plug in the external monitor or projector.
FnF8 -> CRT on only
FnF8 -> Both on
FnF8 -> (screens shut off & then back on) - Both on again
FnF8 -> CRT on only
FnF8 -> laptop on only
FnF8 -> dead. backlight may or may not come back on, but display won't.
At this point you have to power-cycle the unit to recover.
I'm running Dapper with current upgrades as of 2006/06/18. This is reproducable under both the 2.6.15-23 and 2.6.15-25 kernels.

Oh - one other thing. When display is on BOTH laptop and external monitor/projector, the display on the computer is shifted down by about a quarter inch or so - there's a top bar of gibberish. Mouse entry, however, is not shifted down. The result is that in order to point and click on something (a hypertext link, a file folder, whatever) you must click *above* the link/item/whatever.
