[Bug 585258] Re: switching to external VGA monitor does not work anymore on dell precision M4400 and Ubuntu 10.04

[Lucio Crusca]

Recent Ubuntu updates made the problem appear also in latest 9.10
kernel, namely linux-image-2.6.31-21-generic. However with that kernel
(and only that), if I press Fn+F8 during boot before gdm starts, the
external vga gets the output, but after gdm has started Fn+F8 stops
working and does nothing.

Since latest updates did not touch linux-image-2.6.31-21-generic, but
only other packages, I suspect this problem could be related to other
packages also/only, but I don't know how to check if it's such a case.
It seems there were no udev nor acpi updates recently, and I don't know
what other package could influence the support of Fn+whatever.

Any help appreciated.
