xscreensaver tells me the following all the time: imsmap: wanted 50 writable colors, got 0 imsmap: wanted 50 colors, got 26 this is even when i use 32bit depth on my screen and obviously has enough colors for all my other program xdpyinfo output: screen #0: depths (1): 24 <snip> i have a RivaTNT2 card
It's trying to get 'writable colors', where it can cycle the colormap. This is usually only available if running in 8bpp mode.
