Hi,
My Intel i810 supports resolution of 1024 x 768 on my monitor when I am running Winblows.
However, even though I have made changes to my Xfrre86Config file, there seems to be no effect while using RH 9.0.
The same card gave me the 1024 x 768 resolution on RH 8.0

Here is my XFree86Config File

# RgbPath is the location of the RGB database. Note, this is the name of the

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"

THankx in advance...

Try using "Ctrl & Alt & -" and "Ctrl & Alt & +" to switch between resolutions.

I have tried that...
It seems to work on Mozilla but I want to change the resolution on my Desktop. I have tried using rhn-desktopn-config and set it to 1024x786 but when I restart the X-Server the resolution is set back to 800 x 600

Thankx in advance...
