Getting X Windows resolution

[binarydemon]

Hi,

I was trying to have a script determine the resolution used by X Windows- most of the examples on the internet utilize xdpyinfo or xrandr but neither of these seem to be included in TinyCore x86 by default (I'm sure one of the tcz's in the repository include these, but I'd rather not keep adding bloat).  I see there is a -screen parameter in first line of .xsession, can I pretty much count on that being the working resolution or is there a chance when running that Xvesa command that it might fallback to something else or be overridden by a boot vga= parameter?

Is there another method I might be overlooking?

Xorg-7.7-bin contains xdpyinfo and xrandr - if you are concerned about the size, you could always hack the extension to only contain what you need.

Hi binarydemon
If you go here:
http://forum.tinycorelinux.net/index.php/topic,13793.msg77139.html#msg77139
you'll find the C source code for a small desktop clock. You can lift the  GetScreenParams  routine to retrieve screen resolution.

Hi binarydemon
Attached is a small C program for retrieving screen information. Install compiletc, xorg-7.x-dev and sstrip. Then run the
CompileScreenParams script to compile it. Compiled and stripped it's 1700 bytes and outputs the following:

Code: [Select]

tc@box:~/guilib/ScreenParams$ ./ScreenParams
Screen=1920 x 1080  DPIx=95 DPIy=94
tc@box:~/guilib/ScreenParams$

Can I use this script to change the resolution, because the width is a little warped. This causes problems after a certain time, i.e. when working for a long time.

I am working with flux, so the icons are in the center on the bottom of the screen. Don't know if this is X. Here some information about my HW:

Hi windundgeist
No, the program can only retrieve the screen information, not change it.

Ok. Other possibility to set the 1280x800? With boot code probably? VGA?
