Registered by

Current version of Xpresser is incompatible with the upcoming version of Ubuntu due to the GTK version change. Xpresser must be ported to GTK3 for it to continue to be used in 12.04 and beyond.

Whiteboard
One of the issue currently is that in GTK3, there is no quick way to get a numpy array of pixels from a framebuffer, which is how Xpresser worked in GTK2.
[Sylvain Pineau] Based on Gustavo's work to port the application to GTK3, one possible solustion is to use a cairo surface to populate the framebuffer. As we don't need the alpha channel, we have to slice the resulting array differently to perform the comparison.
(?)
