Bug 679110

+++ This bug was initially created as a clone of Bug #678971 +++

Description of problem:

On my Fedora 14 workstation, My ViewSonic VA2431wm monitor is detected without issue.  However, when I connect that monitor to my ASUS notebook (via VGA adapter in both cases) and try to use it as a secondary monitor, it is not detected properly and only offers a maximum 1024x768 screen resolution instead of 1920x1080.

Version-Release number of selected component (if applicable):

Fedora 14.
Linux 2.6.35.9-64.fc14.x86_64 #1 SMP Fri Dec 3 12:19:41 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux


How reproducible:

Always.

Steps to Reproduce:
1. Connect VA2431wm monitor to VGA port on a notebook computer.
2. Open display preferences and note the maximum resolution is 1024x768.
3. 
  
Actual results:

Maximum resolution is 1024x768.

Expected results:

Maximum resolution should be 1920x1080.

Additional info:

I ran the following commands as root and was able to get full screen resolution out of the monitor:

# xrandr --newmode "1920x1080_60.00_hsync" 148.50  1920 2008 2052 2200  1080 1084 1089 1125 +hsync +vsync
# xrandr --addmode VGA-0 "1920x1080_60.00_hsync"
# xrandr --output VGA-0 --mode "1920x1080_60.00_hsync"

Note: the modeline setting above was taken from my PC's Xorg log file with the monitor attached.
