No luck with -display and any IP address I can think of - my address
from the net, my local address.
However, there is xdpyinfo -queryExtensions and in that data I see this:
m...@gandalf ~ $ xdpyinfo -queryExtensions
name of display: localhost:10.0
version number: 11.0
vendor string: The X.Org Foundation
vendor release number: 10503000
X.Org version: 1.5.3
maximum request size: 16777212 bytes
motion buffer size: 256
<SNIP>
screen #0:
print screen: no
dimensions: 1280x1024 pixels (338x270 millimeters)
resolution: 96x96 dots per inch
depths (7): 16, 1, 4, 8, 15, 24, 32
root window id: 0x80
depth of root window: 16 planes
number of colormaps: minimum 1, maximum 1
So on my dad's machine, which I know I set up as 1280x1024, I get the
right answer.
On my mom's machine however, which I have to
m...@desertflower ~ $ xdpyinfo -queryExtensions
name of display: localhost:10.0
version number: 11.0
vendor string: The X.Org Foundation
vendor release number: 10503000
X.Org version: 1.5.3
maximum request size: 16777212 bytes
<SNIP>
screen #0:
print screen: no
dimensions: 1280x1024 pixels (338x270 millimeters)
resolution: 96x96 dots per inch
depths (7): 16, 1, 4, 8, 15, 24, 32
root window id: 0x80
depth of root window: 16 planes
and locally on my machine here I get the same info:
screen #0:
print screen: no
dimensions: 1280x1024 pixels (338x270 millimeters)
resolution: 96x96 dots per inch
depths (7): 16, 1, 4, 8, 15, 24, 32
root window id: 0x80
depth of root window: 16 planes
so I'm not sure if I'm looking at their machines or just my own?
Actually, on my mom's machine it seems it's not really screen #0, it's
screen #1 according to the config file, but maybe Xorg actually calls
it screen #0 when it's tunning. None the less her default resolution
is supposed to be 1024x768 - she has an old small monitor:
