All Toshiba's laptops have an hardware support for swiching video between internal and external display. Untill upgrading video driver to lenny (Debian) it worked fine. After upgrade i observed strange behaviour: Display didn't want to switch (was blank) or i had second screen (i have 2 screens defined) on both displays (instead of the first one) and it was also wrong scalled. after downgrading to stable (xserver-xorg-video-i810) problems went off.

Can you attach your X log from when you tried this?

I think Hong already fixed this, reassigning.
Can you switch display with xrandr? For display switch hotkey support, it may be broken with intel driver since intel driver does modesetting by itself while i810 driver relies on vbios to do modesetting. Since hotkey is serviced by vbios, vbios configs the graphic hardware without intel driver's knowledge. The graphic hardware may be in inconsistent state. So you may need to stick with xrandr to do display switch with intel driver. Thanks, Hong
Reassign Hong's bugs back to the default for triage.
support should have been in. Problem it varies depends on the platform. If the platform doesn't even fire an ACPI event or a special acpi event need special module to handle, likely hotley won't work for you. I'm close this bug because it's too generic, please open new bug for specific platforms. thanks. Michael
