The sole purpose for my RPi is to use the DVI out functionality and I am going to rip apart a 19" LCD HD screen and build it into my own frame.
I already did this with a very old notebook a few year ago, and being a huMAN, I want bigger and better now!
I tried the GL slideshows in Debian Squeeze from the RPi site, but that gives me 0.1FPS on any option. I suspect its because X is not using the OpenGL API yet. (as pointed out It is OpenGL:ES)
Then, I went and installed the XBMC distro and was very nicely surprised that it can play avi movies encoded in xvid out of the box. It was a bit slow in the UI, but it's really fascinating. There is a built-in screensaver there, which is a lot faster, but there is very little to no control over the settings of the screensaver.
Is there something I can just load to use OpenGL screensavers for the RPi, in any distro and any configuration? I am not scared to go into hectic installs.
