• add option to make layout default on startup by means of desktop environment integration

  • implement missing xrandr 1.2 features: reflect, additional modes (for forcibly applying saved layouts so they are already active when an output is connected), fb, fbmm/dpi

  • call xrandr without blocking

  • receive notifications on changes (XRRScreenChangeNotify)

    • useful resources: <http://www.mail-archive.com/sawfish-list@gnome.org/msg03630.html> (a patch to sawfish for xrandr event support), Xrandr.c (that defines XRRSelectInput), SelInput.c (compare XSelectInput /XRRSelectInput), ./eventdemo.py

  • don't reset displays moved over edges; instead, move as far as possible

  • allow setting dpi

  • integrate related settings: (might end up writing a complete configuration manager, which is not my intention)

    • xsetwacom
    • gnome-panel layout (is this 1.3's --primary?)

  • integrate new 1.3 features (projection matrix, panning (requested in <http://forum.eee-pc.de/viewtopic.php?t=8035>))

  • be more intelligent about future xrandr versions (cf debian #523903)

  • read --props, parse edid (using parse-edid from read-edid), maybe even offer setting properties

  • make script properties editable (and explain what it does)

  • provide example scripts

    • for rotation
    • for setting background images?

  • have inactive outpus in a side bar, showing their size?

  • gracefully handle

    • loading files describing invalid state
    • naming transitions (LVDS -> LVDS1)
    • unimplemented options (--right-of)

  • setting configuration based on hardware: this calls for two additional programs -- one that listens for hardware changes and executes a command when something changes, and one that acts on a change and sets the last used configuration with that hardware (or something else configurable). Martin Insulander suggestes this (with my comments in []):

    1. When …

      1. the monitor setup changes (trigger through hal or udev)

        [afaik there is no such thing currently in udev; i'd rather have xrandr with a --listen / --on-change-exec option. furthermore, other mechanisms that do the same thing should be identified to avoid conflicts]

      2. X starts

    2. Identify all monitors through EDID

      [using this is already on the todo list]

    3. If the setup …

      1. has been used before:

        4a. Set the setup that was used last time with this configuration.

        [that requires the xrandr shell scripts to have an additional line, something like "ln -sf ../$MYFILENAME > ~/.screenlayout/last_used/$HASH_OF_HARDWARE"]

      2. Else

        4b. Show a notification about new screen setup

        4c. Clicking on the notification starts for example Arandr
