Ok, I did as you said and I called that function in the following way (note:
crtc.id is equal to resources.crtcs[it]):

cookie = self.conn.randr.GetCrtcInfo(crtc.id, resources.config_timestamp)
info = cookie.reply()

but I get this:
File "/usr/local/lib/python2.5/site-packages/xcb/randr.py", line 227, in
__init__
    self.outputs = xcb.List(self, count, self.num_outputs, 'I', 4)
xcb.Exception: Protocol object buffer too short.

This is weird as I have no problem when I call GetOutputInfo():
cookie = self.conn.randr.GetOutputInfo(output.id, resources
.config_timestamp)

I have tried the latest release of xpyb (1.0) too but it doesn't solve the
problem.

Any ideas?
