finding monitor or screen resolution in Linux with standard python module

[akbar]

I googled and searched in archive. All I can find is finding
resolution with Tkinter and pygame. Any idea to find monitor
resolution with standard python module?
I can check from output of: xprop -root
_NET_DESKTOP_GEOMETRY(CARDINAL) . The problem is when you use Beryl or
Xgl, it is not correct anymore because Beryl or Xgl set this value
from amount of workspaces multiplied by monitor or screen resolution.

I'm using Beryl too, and xwininfo -root gives te correct resolution.

Perhaps read-edid [1] or ddcprobe [2] would work since they read the
info strait off the EDID. You could probably read the EDID from python
(mabye through the xlib binding?), but no need to reinvent the wheel.

A method 'screen' from Python X Library looks promising:
http://python-xlib.sourceforge.net/doc/html/python-xlib_16.html#SEC15

More, or less if I understand right you just need to request from
server dimensions of the screen, over x protocol of course. So it will
be something associated with Xlib.
