The purpose of this wiki page is document multi-head (multiple monitor) testing completed during the Precise development cycle.
This page will define the test use cases, the packages tested,
dual head testing in XFCE
there were 2 test cases i used for dual monitors. these cases are described as follows...
this would be for a presentation maybe. having the same image on both the main display, and a secondary display, such as a projector.
this would be where the desktop is actually extended onto both monitors making one big desktop.
mirroring the display is quite simple with the included tool from XFCE/Xubuntu located in the menu under "settings" - "settings manger" - "display". also, the package LXrandr provides similar functionality. http://packages.ubuntu.com/search?keywords=lxrandr
to enable, and manage dual head spanning, the only tool that worked for me (with a GUI) was arandr. http://packages.ubuntu.com/search?keywords=arandr the different displays were easy to find, configure and rotate using the GUI arandr.
arandr and 'monitor settings' in the menu have the same icons.
* between these 2 tools, we can cover whatever the end-user needs.
failed packages, and why
grandr failed. i couldnt enable spanning with it, and there were quite a few 'greyed-out' options.
