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):
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
Modes "800x600" "640x480"
User can set any resolution in redhat-config-xfree86; it is ignored.
Expected Results: /etc/X11/XF86Config
Modes "1024x768" "800x600" "640x480"
01:00.0 VGA compatible controller: ATI Technologies Inc Rage Mobility P/M AGP 2x
This behaviour was also found on an Nvidia Geforce 2 card.
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.
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.
I am unable to reproduce this on my Compaq Presario 1700T, which has an ATI Rage
Mobility video chipset. Closing as 'worksforme'
