Subject: Reporting screen/laptop orientation data to userspace
Date: Sun, 29 May 2011 10:49:19 +0300 [thread overview]
Message-ID: <4DE1FA7F.3050308@users.sourceforge.net> (raw)
Hi all,
the WMI interfaces in some Lenovo Ideapad laptops provide notification
callbacks when the laptop orientation changes, reporting 4 different
values defining the new orientation.
I'd like to extend the ideapad-laptop driver with this information; but
how should it be reported to userspace? I initially thought of the input
subsystem, but I cannot find any suitable event codes; then I would
probably export it as a device under /sys, or are there better options?
Are there other devices which provide coarse orientation data to
userspace, which I might want to use as a reference?
I guess that at least some display screens have this feature.
TIA,
Alberto
