Subject: [PATCH]Panning: Set panning state in xf86RandR12ScreenSetSize()
Patch-mainline: to be upstreamed
References: boo#771521
Signed-off-by: Egbert Eich <eich@suse.com>
Right after verifying the panning area the per-crtc panning state should
be set.
This fixes panning when set in the configuration.
