Bug 480620

Description of problem:
The first time i connected an external monitor to the vga port of my laptop (a lenovo Y410), and restart X, the system failed to detect the external monitor (ie: the motnitor, still showed the "no signal" status message).

After this, I tried using system-config-display to configure dual head, but here the "Second Video Card" drop down was empty (so, i presume that is the problem, for some reason, the hardware is not visible to the driver). When I
tried to save the configuration, inspite of the empty "Second Video Card" option, i naturally got a traceback:

[steve@laptop ~]$ system-config-display
Traceback (most recent call last):
  File "/usr/share/system-config-display/xConfigDialog.py", line 212, in ok
    if card.getDescription() == self.secondVideocardOptionMenu.get_menu().get_active().get_data("NAME"):
AttributeError: 'NoneType' object has no attribute 'get_data'

So, i unchecked the dual display option and restarted X. Now, the external monitor did get the signal but it now runs as a 'clone' (ie: the screens on the primary LCD and the external monitor as the same). Also, the external monitor
resolution is stuck at that of the primary display.

A sosreport is attached. Please let me know if you need anything else.

How reproducible:
Always

Steps to Reproduce:
1. Install F10 with latest updates on lenovo Y410 laptop
2. Connect an external monitor
3. Try to configure displays to have individual desktops
  
Actual results:
The external monitor display is a clone of the primary display and it's resolution is limited to that of the primary display.

Expected results:
The external monitor should have a separate display (ie: the desktop should span across both exteral monitor and laptop LCD)

Additional info:
I am assuming here that the component select / rpm mentioned in this summary provides what is referred to as the 'intel' driver in the xorg.conf file.
