FC7 82Q963/Q965 Integrated Graphics Controller, dual head and spanned desktop

[Andre ten Bohmer]

Hi,

Running FC7 on a FUJITSU SIEMENS ESPRIMO P with two connected LCD
screens, I'm unable to configure a spanned desktop (both displays show
the same workspace). When using the system-config-display and adjusting
the settings, clicking on the OK buttons results in no response;

.xsession-errors :

Traceback (most recent call last):
  File "/usr/share/system-config-display/xConfigDialog.py", line 137, in
ok
    lower_vrefresh, upper_vrefresh =
string.split(str(self.second_monitor_vrefresh), "-")
ValueError: need more than 1 value to unpack

Also fiddling with xorg.conf and compiling the x.org intel driver from
source was to no avail. 

Probably it is not possible at all, but maybe it's a bug or I'm missing
some config options?
Any ideas?

Tia,
André
