Subject: [PATCH] monitor-manager: Consider external layout before default |
|
linear config |
|
|
|
In case of no existing configuration, we use a default layout of |
|
aligning attached displays horizontally. This sidesteps any layout |
|
configuration that is done externally, for instance via xorg.conf, |
|
which is not desirable. Instead, base the initial configuration on |
|
the existing layout if it passes some sanity checks before falling |
|
back to the default linear config. |
