This page is getting confusing. It started off being about screen- and stylus rotation according to physical orientation (tilt) using the HDAPS accelerometer. Then it became about rotation according to swivel-up and swivel-down, but with parts of the original page still there. Wouldn't it be nice if we used the term "Active Rotate" for one thing only?
Also, the last update (21:29, 20 February 2009 1,278 (Talk | contribs) (1,846 bytes)) describes how to do it using a ACPI events defined in /etc/acpi/event/. Isn't this description Debian/Ubunutu specific? I thought all distributions handled ACPI stuff differently (I have Ubuntu, so I can't verify that, but see https://wiki.ubuntu.com/AcpiSupportDeprecation). Finally, I just wrote a similar description for Ubuntu Intrepid on X61 Tablet, and my experience was that running xrandr via a script run from /etc/acpi/event/* would not work unless I had restarted /etc/init.d/acpid from that X-server. To work around that I had to use some extra functions copied from /etc/acpi/rotatescreen.sh in Ubuntu. --Gomyhr 13:37, 21 February 2009 (UTC)
