Well, I just finished installing 7.04 and indeed the video switching works just fine there.
In 7.10, I suspect it's a problem with the hotkey keymask in /etc/modprobe.d/thinkpad_acpi.modprobe the contents of which are, by default: options thinkpad_acpi hotkey=enable,0xffff8f experimental=1 As near as I can tell, this should set the mask to 0xffff8f in /proc/acpi/ibm/hotkey to that value, but instead it has the following contents: status: enabled mask: 0xffffff commands: enable, disable, reset, <mask> as you can see the mask is trivial, capturing all key strokes. In 7.04, Fn+F7 doesn't generate an acpi event. I'm guessing it goes straight to the hardware and does the right thing. To fix this, I somehow have to get the mask in /proc/acpi/ibm/hotkey to be what it was in 7.04, but all of my attempts to change it have been ignored.
