You can run a xscreensaver hack on the command line with the -root option and it will draw on the root window. However the root window is normally hidden by desktop backgrounds. If you log into a failsafe xterm session you can see it working. It should be possible to write a small wrapper that does the same as the xscreensaver in this regard: make a full screen on-top root window and call an application to draw on it.
For rendering directly to file, usually the drawing is heavily accelerated by the graphics card. So if you don't want to see it you may be able to render to off-screen buffers in the graphics card, or do the slower pure software rendering. OTOH maybe there are flash applications around to make and distribute such slideshows in a more bandwidth and storage friendly manner than to record a movie out of still pictures? The upstream, mainly sole developer is jwz, see http://www.jwz.org/xscreensaver/ You may send patches to him directly. He also reacts to Debian bug reports from time to time, so that is another possibility. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/671514 Title: xscreensaver-getimage and xscreensaver-getimage-file don't respect "chooseRandomImages: False" in .xscreensaver -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
