There doesn't seem to be any info out there on the output format of an FB dump, apart from people saving the files with a .raw extension. Maybe do this and try it in gimp?

It seemed you only knew how to make manual screenshots! The request for a screen shot operation that leaves the mouse pointer in the image has come up several times on the XFree86 mailing lists (please google for it). AFAIR the discussions can be summed up as: no, you can't currently do it with a vanilla XFree86, yes, some X servers have an extension to do, yes XFree86 could also conceivably get such an extension, no, nobody has written one yet, yes, there are in principle other solutions but they are hacks too -- and anyway, you have the source code, you can do whatever you like. Please google now. -Peter ___ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86

It was merely puzzled for some months why it was rejected. Now I'm bewildered.
