I've had a couple of people from Sun ask me privately about how some (or all) of that functionality can make it into the next XFree86 release. The standard answer is that the first step is for those advocating it to write up a proposal submit it to public review. Getting this type of stuff in through the back door via a tame committer is not the right way to do it. For all the interest Sun has shown in this, I haven't seen any such proposal yet. I was surprised that Sun didn't do it through X.Org, since that's surely the appropriate way for a major X.Org member to handle extensions that are intended to have status close to that of the core protocol. Maybe the review process there was the sticking point? Or maybe now you're waiting for X Consortium / X.Org v3.0 (or whatever it's being dubbed) to come into existence? The whole thing doesn't make much sense to me...

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

It seemed you only knew how to make manual screenshots!

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?

Am Freitag, 11. Juli 2003 14:16 schrieben Sie: > [EMAIL PROTECTED] well, The thing is that I know it must be possible to do it. Commercial products do the same job. Camtasia for example records on windows the screen. I can allready do it using xwd or other tools to make the screenshots. The problem is that with these tools the mousepointer disappears when a screenshot is made. The user can no more work properly. So I'm thinking in the way to do it as the VESA driver refresh the screen.Just send the framebuffer output, in this case not to the display but into a file with a very simple command like .
