The "ripples" hack from xscreensaver-5.08 always uses a screen image, regardless whether the option -water is present, omitted, or -no-water is given. Without -water, ripples should use a black background. Also, ripples does not recognise the options -no-stir and -no-oily mentioned in the man page.
Created attachment 190626 [details, diff] Proposed patch for both ripples hack and man page * Make ripples respect the -water option, not using a desktop image by default * Remove -no-{water,stir,oily} options from the man page
This patch doesn't really work.. before applying it I can see ripples on my grabbed desktop image, after applying it it's all just black blackground with ripples (started from xscreensaver-demo's configuration gui) reopen if you got something else, thanks
I mean it didn't work even when grab desktop image was switched on
Works for me. You have to explicitly add the -water option to the command line: * Start xscreensaver-demo * Choose "Ripples (desktop)" in the list * Click "Settings..." * Click "Advanced >>" * Add "-water" to "Command Line:" For some reason the "-water" option is not kept. I'll look into it, when I find some time.
