I'm not suggesting you actually backport packages yourself - especially as I don't know which packages you need... Sorry for the poor advice - I just checked and it doesn't appear any of the acpi packages are in squeeze-backports. > > Bye, > Bruno > > > I'd suggest first try interupting the boot at the grub screen, and editing the boot command to replace "acpi=off" with "acpi=force" If that gets you the Function key and your full screen resolution ranges - just edit /etc/default/grub and update-grub. It's not likely that will fix the problem - so... First confirm that Debian can support the ASUS "make-up-[beep]-as-we-go-along" ACPI ;-p by trying a Sid live usb-hdd image first (if that works - it's less work to backport to Squeeze):- http://live-build.debian.net/cgi-bin/live-build select usb-hdd, Sid, kde-core (or gnome-core, or xfce) to test screen and function keys). If that fails to give you ACPI support you'll need to try Unstable - though I suspect Testing will do it (based on your Ubuntu experience). If Testing works for you - determine which modules are loaded, and note the kernel. Then post your results and we (the list) can try and help you from there. Just to increase your options - I've had some success (with different ASUS netbooks) just downloading eeepc-acpi-scripts from Testing and installing it's requirements from Testing. It's a fiddly process that also requires pinning. Strongly suggest you try Sid first, then consider which packages you need - and whether you want to stay with Sid or backport/mash/hack those packages into Squeeze. NOTE: you want "bleeding-edge" hardware, you need "bleeding-edge" software, and Debian needs testers... those of us that run stable salute your sacrifices ;-p Cheers -- "Always question authority, and demand the truth." — Bill Hicks -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
