If you have several screens and enlarge your desktop with a window manager to several X screens width / height, it can easily exceed 32767. No, it can't exceed 32767; you might /want/ to exceed that, but that's a different matter. Is this fact known to X developement society? Yes. E.g. if you want to create a viewport on a much larger canvas, you can't just create a child window the size of the canvas and scroll by changing its (parent-relative) position. You have to implement transformation and clipping yourself. The limitations on the core X protocol aren't likely to change; it would cause too much breakage. For graphics, you can just use Render, cairo, OpenGL, etc. I don't think that the 16-bit limitation on the size of a window is likely to be a problem for the foreseeable future (apart from anything else, you're likely to run into memory issues with backing store or compositing buffers before that). If you want large virtual desktops, the WM just needs to be creative. -- Glynn Clements gl...@gclements.plus.com ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
Re: Any plan to promote coordinats to 32 bits?
Hi Teika, As far as I know there hasn't been a lot of development to fix that, theres not enough pain for now. Unfourtunatly it would mean re-implementing a lot of X11's core protocol as new extensions. Probably a better way to fix that would be to create X12, or to use something different like e.g. Wayland. But don't get me wrong, I don't think Wayland will solve all problems magically just because its not called X ;) - Clemens ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com

It's not a simple promotion but breaking compatibility with the existing protocol - it's on the list of things to fix if we ever get around to a major compatibility breaking revision: http://www.x.org/wiki/Development/X12#A15bitcoordinatelimit In fact, 16 bits are not sufficient these days. If you have several screens and enlarge your desktop with a window manager to several X screens width / height, it can easily exceed 32767. Several? I've yet to see many common monitors larger than 2560 pixels, so that's still 14 screens wide/high. Is this fact known to X developement society? Of course.

But! InSitu's (virtual) wall is already 20480x6400 which is less than an order of magnitude away from the 16bit limit. The next research team that does this sort of insane setup will probably blow the limit. And we did have an X running on that (using metisse), fully capable of using the entire screen real estate.

Right - DMX folks were worrying about this years ago - it's not outside the realm of special cases, just not the average desktop. -- -Alan Coopersmith-alan.coopersm...@oracle.com Oracle Solaris Platform Engineering: X Window System ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
