Hi all,
Up until today everything has been fine with CentOS on my Toshiba laptop.
I booted into CentOS 4.3 today and Kudzu detected my video card for some reason. I let it configure it (wish I hadn't now).
I can still get in. X and Gnome work. But the video resolution is 800x640. The LCD is capable of 1024x768. I cannot change it using Gnome tools or direct editing of /etc/X11/xorg.conf
With the Gnome "Display" system tool I cannot change the monitor to "Generic LCD Display".
Any help you can offer on getting the 1024x768 display mode to work again would be appreciated.
Here are the relevant sections from /etc/X11/xorg.conf
Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "Unknown monitor" HorizSync 31.5 - 37.9 VertRefresh 50.0 - 70.0 Option "dpms" EndSection
Section "Device" Identifier "Videocard0" Driver "i810" VendorName "Videocard vendor" BoardName "Intel 852" EndSection
Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 Modes "800x600" "640x480" EndSubSection EndSection
Try adding 1024x768 in the modes under the Screen section. Then reboot and see if there is any change.

I fixed it!
I booted up Knoppix (which uses xfree) for some hints. I found that maybe be the horz/vert refresh rates needed ajusting.
Going back to CentOS, i found: HorizSync 31.5 - 37.9 and and changed it to: HorizSync 31.5 - 93
and changed: Modes "800x600" "640x480" to: Modes "1024x768" "800x600" "640x480"
The key was to change the HorizSync to a wider range. Just changing Modes to include 1024x768 was not sufficient.
The system is a laptop with an LCD screen.
