Comment 3 for bug 671514

Please see the man page for xscreensaver-getimage for an explication of the chooseRandomImages option. Setting it to false does not mean images should be selected sequentially. So the "bug report" here is invalid.

However, a feature to have a sequential slide show sounds like a good idea. I would encourage you to make an "upstreamable" patch. I don't see why Ubuntu should carry such a delta in form of a undocumented "hack". There is also a couple of issues in your patch (which seems to have been released in Natty without any review) which I have tried to address in the attached patch:
1) there is no checking for index overflow once the image list has run out
2) the hard-coded index counter file name is not portable
3) the counter is incremented, then decremented in a conditional clause (confusing)

I have omitted the check for chooseRandomImages in the configuration file, and just rely on the existence of an index file. It might make sense to check for a "chooseSequentialImages" option instead, which also needs to be honoured in other code. But the upstream developer might have other suggestions for how to implement this.

BTW, is this part of a bigger plan for something in Ubuntu, or just a private "itch"?
