- Date: Mon, 28 May 2018 23:39:47 +0000 (UTC)
commit 6ee4265571308b468791abef6a9094ab39ea9370
Author: Benjamin Berg <bberg redhat com>
Date: Fri Nov 24 13:13:09 2017 +0100
display: Remove unused old display arrangement code
Remove the code that has become unused with the new arrangement widget.
There are more possible cleanups as there is some code duplication
between cc-display-panel.c and cc-display-arrangment.c at this point.
