Re: Xnest on Centos 6

well from a box called jeewani it worked!
Xnest -query genie :1 worked
jeewani has only one monitor
to a large extent the problem is solved

but I still want to run Xnest from my original box called onottar for short
onottar is running Centos 5.5, it also has two monitors (dual head) with an nvidia quatro graphics card
on onottar I can run Xnest back to itself
Xnest -query onottar :1 works


in genie:/var/log/gdm
there are two files that correspond to onottar
10.117.202.63:1-greeter.log
10.117.202.63:1-slave.log


greeter.log has a message
Xlib: extension "RANDR" missing on display "10.117.202.63:1.0".

** (gnome-settings-daemon:19737): WARNING **: Unable to start xrandr manager: RANDR extension is not present
which I believe is simply designed to confuse people

and also this:
** (gnome-power-manager:19750): WARNING **: No idle counter.
Xlib: extension "DPMS" missing on display "10.117.202.63:1.0".
<unknown>: Fatal IO error 11 (Resource temporarily unavailable) on X server 10.117.202.63:1.0.

can anybody help me?
