[Bug 539477] Re: Video out hot key sends super + p + return on many upcoming Dell & HP systems

[houbahop69]

Adding acpi_osi=\"!Windows 2009\" at the and of the "linux" line the Fn key works again.
Thanks a lot for this work around!

(Notebook: Dell  Precision M2400,  Ubuntu 10.04 x64)

After an update the trick was lost so I changed the following line  in the file /etc/default/grub
GRUB_CMDLINE_LINUX="quiet"
to 
GRUB_CMDLINE_LINUX="quiet acpi_osi=\\\"!Windows 2009\\\""

It works fine for Fn F8 and there are no more problems with update-grub
