Code: bluesabre/display-settings branch

Target: Xfce 4.12, Implementation: 100%

• Support extended desktop mode for multiple monitors
• Improve minimal dialog

Status: Wait for testing/bugreports for 4.11.0.

Target: , Implementation: 75%

• Replace treeview with iconview (DONE)
• Support xfce4-notifyd's themes for the identity-popups
• Support setting the primary monitor (Related bug: 9338) (DONE)
• Create “display profiles” (save setups based on EDID) (DONE)

• Implement support for extended desktop mode
• Improve minimal dialog
• Use new big icons to make minimal dialog easier to understand
• Implement display identification popups
• Improve applying new settings (now works with Nvidia's proprietary driver as well)
• Fix small naming inconsistencies

The minimal dialog can be called when a new display is plugged in (given that the laptop send the appropriate signal). It should provide users quick access to four of the most-used modes:

• Only Display 1
• Extend desktop to the right
• Mirror displays
• Only Display 2

The “Advanced” button opens the normal display-dialog.

The main thing that changed here are the comboboxes to change the monitor position and the mirror-checkbox. (Note: the mirror-mode in the position-combobox only sets the currently selected display to mirror _one_ other display. This is mostly relevant in 2+ displays setups.) The comboboxes give the user a way of positioning always 2 displays relative to each other. In total, users can still position as many displays as they have. Four positions are available: left-of, above, right-of, below.

For users to more easily know what display they're currently modifying, we decided to implement “identity-popups”. These show the name of the display (same as in the treeview) and the resolution. These popups are currently shown at the bottom of the respective display.

Hotplugging Scenarios

• with an external display connected, internal display disabled, we want to re-enable the internal display when the cable gets disconnected
• when connecting an external/additional display, we could show a notification-popup with an action-button to either enable the display directly and/or open the display-dialog
• when the laptop-lid gets closed (e.g. in a docking-station), we should disable the display (currently this doesn't happen reliably with xfce4-power-manager, maybe this functionality should reside in xfsettingsd?)

Minimal dialog:

• Add the 10sec-reset-timeout dialog just to be sure

General:

• Fix 3 commit authors (merge locally, then rebase interactive on origin/master and set a new committer)
• Celebrate the release!
