LCD Touch Screen

[GarthBock]

Ok....here is another idea for the RasPi. Can the LCD Touch Screen display an image such as four topical buttons which when touched would display an image or set of images on an attached LCD monitor on the HDMI port ? Here is my idea.......the 3 inch or 2 inch LCD Touch Screen display would be sectioned into a 2x2 or a 4x4 matrix. In each cell would be topics such as News, Weather, Sports, etc. When you touch one of the "buttons" or topics on an attached LCD computer display would be images or information that relate to that topic. Touching weather would display a rotating weather map slide show. Sound feasible ?

It's possible, but would take a bit of work.

It's fairly difficult to make a program that presents video in two different X sessions. It's easier to run different programs in each X session and find ways for them to communicate. You can do that with a client-server architecture, where a daemon runs in the backgound with no video output and clients in each X session display video or graphics the server gives them. You can also use a peer-to-peer model, using things like FIFOs to let a program in one X session pass information directly to a program in another X session.
