physical rotation doesn't rotate screen and input automatically

[Matt Fischer]

Once Bug# 1092952 is solved and we are able to listen for rotate events from the kernel, then we need to hook this signal in with the gnome-settings-daemon code that tracks rotation status and performs the xinput and xrandr rotation events.

Bryce has written an xrotate script that maybe we could attach to the rotation events, but in theory we shouldn't need it.

Bryce adds, "Theoretically there should be code in gnome-settings-daemon (or gnome-desktop) which listens for xrandr events and rotates the input. So when we have proper handling of the sensor we can hook that to the gtk events and let g-s-d rotate the input, and then xrotate simply becomes a debugging tool."

Really, this bug report should be split into two pieces: First, the kernel needs to communicate the rotation events up. This is probably going to require plumbing in the sensor driver. Second is the task of hooking this signal in with the g-s-d code that tracks rotation status and performs the xinput and xrandr rotation events.

So, as per Bryce's advice, I've split this bug into two pieces. Bug# 1092952 is for the kernel half of this bug, and this bug is now just for the g-s-d half.

[Jani Monoses (jani)]

The kernel already had this just was not entirely obvious.

So the remaining task is hooking up g-s-d instead of using a standalone daemon as in the test app linked from the blueprint.

Issue seems to have been resolved because physical rotation does rotate my screen

[Oliver Grawert (ogra)]

it has been worked around by some scripts ...
nontheless it should be properly fixed in gnome-settings-daemon instead, closing the nexus7 task but leaving g-s-d open....

ubuntu-defaults-nexus7 (0.41) raring; urgency=low

  * add acceld.conf upstart job, acceld binary to /usr/bin
    and 95-acceld_start XSession.d file this enables auto-rotation of
    the screen. it can be disabled by editing /etc/default/acceld
