Description of problem: if you try and set screen resolution from graphical tool
"System" -> "Administration" -> "Screen" (I'm translating from Italian version),
it fails, setting a large resolution in 16:9 format (see attached pic). Tried
with various resolution, emulating several monitor types. You can correct this
behaviour just manually editing /etc/X11/xorg.conf.

Version-Release number of selected component (if applicable): Default shipped
with Fedora Core 6 Test 3.


How reproducible:


Steps to Reproduce:
1. From application bar, go in "System" -> "Administration" -> "Screen"
2. In "Hardware" tab, choose a monitor type, e.g. choose "Generic LCD Display"
-> "LCD Panel 1024 x 768".
3. In "Settings" tab, choose a different resolution, e.g. 1024 x 768.
4. Logout and login again.
  
Actual results:
Screen is larger than expected and in 16:9 format. If you click again on
"System" -> "Administration" -> "Screen", you see resolution is still 800 x 600.

Expected results:
You should be able and see a 1024 x 768 resolution after logout/login.

Additional info:
In /etc/X11/xorg.conf, if you comment out HorizSync and VertRefresh lines, and
then logout/login, default 800 x 600 resolution is applied. You can get
resolution you wish manually editing HorizSync and VertReflesh values.
