Scaling with an embedded X server.
I have a set up where I use Xpehyr to display an X-display inside of an x-window app. I need to increase the resolution of the embedded display but I also need to keep the hosting window the same size. Does anyone have any suggestions on how to scale? Is there scaling in the Xorg server that I could port to Xpehyr? Any ideas would be appreciated.

Re: Embedded X
I got stuck again while porting X11/GTK+ on OMAP. I'm not sure whether it is the right forum for these questions or not but these questions are directly or indirectly associated with Mesa/GL libraries. Dependency chart is like this ... GTK+ needs cairo-pdf and cairo-ps backend cairo-pdf needs glitz installed while compiling glitz, it looks for GL libraries(libGL) while I have only GLES libraries meant for OMAP. I tried cross-compiling MESA for GL libraries but it gave me a compilation error again. This time it was trying to run the previously compiled executable for host(arm) on build(x86) platform. Any help on resolving this issue would be great. Thanks for your concern.

I meant to imply that there are situations where that makes a difference, not that it is universally a good idea. I personally am looking at doing a Linux 2.4.x + uClibc + KDrive (or Xorg; you have me reconsidering now) + FLTK setup, without Gtk or Qt present at all. Obviously, that is not the normal situation for most people. So make the configuration static, or even build Xorg statically. I assume then that the problems I read about had more to do with the particular build that some distribution shipped than anything else. Fair enough. :-) When keithp and I were working on Kdrive on the iPAQ years ago, we had 16 meg of RAM. I think the IBM watch had 8 meg. But that isn't where most of the RAM goes anyway.

Re: Embedded X
uClibc is in heavy development. perhaps you can forward your problems building with uClib to the uClib Mailinglist ? IMHO the lack of I18N (i do not know the state of uClib here either!) is not a problem since it is designed for memorytight systems where it is unlikly to have i18n at all. re, wh Jim Gettys schrieb: Does uClibc actually buy you anything? Last I looked, (admittedly quite a few years ago), it lacked I18N support that most products now require, at least by the time you are doing serious UI work. But times may have changed, and it isn't obvious from the sketchy documentation. At that date, we ended up having to carry glibc anyway, at which point it is moot, and uClibc just ended up costing space, rather than saving it. - Jim On Tue, 2008-10-14 at 09:22 -0700, William Tracy wrote: On Tue, Oct 14, 2008 at 12:40 AM, John Tapsell [EMAIL PROTECTED] wrote: Why not just go for the full X11?

Re: Embedded X
Are there any performance differences between Xorg and kdrive? Is EXA better than KAA? My tests with the very lastest OMAP boards: I found a 20% speed improvement on the OMAP between kdrive fbdev KAA and xorg fbdev EXA. However I didn't not use the most recent version of kdrive for the comparision, so I don't know what the difference is now. I found no memory usage difference between the newest kdrive and newest Xorg. The development effort of writing a new kdrive server (based on Xfbdev) vs writing Xorg driver for a new hardware? I guess kdrive is easier and cleaner, maybe because I'm not at all familiar with Xorg development. It is a harder to get started with Xorg because there's quite a bit of code that you need to get started. However writing the Xorg driver is much cleaner. It is a separate driver, and can be compiled etc completely independently of Xorg. For KDrive, however, it's much more 'built-in'. Also there are things you can do with an Xorg driver that you can't do with kdrive. For example manage your own pixmap memory - essential if you have a UMA system (unified memory). So basically I would join the chorus here in recommending to go with Xorg John ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

There is Building the modular tree at http://www.x.org/wiki/ModularDevelopersGuide, I don't know if it is up to date though. And better use the latest release instead of 7.2 An alternative is to use the same X release as you have installed on your system. Then you can install the development packages from your distribution, and just build the xserver with whatever options you want.
