Description of problem:
Relating to https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=82141 

During install of shrike, it believes that the maximum resolution of the card
(ATI-Rage Mobility) is 800x600; it is infact 1024x768.

After installation using redhat-config-xfree86 the maximum resolution supported
can be selected upto 1920x1440, I'm guessing this drop-down box doesn't really
know the underlying hardware capabilities.

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

How reproducible:

Steps to Reproduce:
1. Dell Latitude L400 (ATI Rage Mobility) 
2. Install, set resolution to 800x600 during install
3. Use redhat-config-xfree86 to change resolution to 1024x768

Actual Results:  /etc/X11/XF86Config 
        SubSection "Display"
                Depth     16
                Modes    "800x600" "640x480"

User can set any resolution in redhat-config-xfree86; it is ignored.

Expected Results:  /etc/X11/XF86Config 
        SubSection "Display"
                Depth     16
                Modes    "1024x768" "800x600" "640x480"

This behaviour was also found on an Nvidia Geforce 2 card.

Comment 2 Brent Fox 2003-06-02 18:28:12 UTC
The behavior that you're seeing in the installer is most likely because the
installer could not probe the LCD monitor.  I suspect that if you picked
"Generic Laptop Display Panel 1024x768" in the monitor list, you would have seen
a resolution option for 1024x768.

Comment 3 Brent Fox 2003-06-02 18:46:41 UTC
Also, a workaround for this bug is to go into the monitor dialog in
redhat-config-xfree86 and select the Generic Laptop Display 1024x768 monitor. 
That should allow the 1024x768 resolution setting to take place.

Comment 4 Brent Fox 2003-09-11 18:55:58 UTC
I am unable to reproduce this on my Compaq Presario 1700T, which has an ATI Rage
Mobility video chipset.  Closing as 'worksforme'
