How to correctly change resolutions under fedora core 2 with xorg.conf?
 

Here's my problem.Whenever i try to switch to a higher resolution from within a an application (game eg doom 3 , rtcw etc) the only thing i get (after switching) is the upper left corner of the screen enlraged! I've tried ctrl + alt + - (or +) either from within the game or @ desktop but instead of getting a higher (or lower ) resolution i get again the upper left corner of my screen enlarged!

What is going on?

I use Fedora Core 2 with an nvidia geforce 6800 video card.

PS Here is my xorg.conf

# no need to change the default.
# 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.

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# 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"

So?

so run "xrandr --size 0" for 1600 x 1200 to "xrandr --size 21" for 320 x 175

there are a number of X interfaces for this tool now too, i just have no idea what they're called.

I've managed to change my resolution nicely wuth xrandr but my problem (read first post) persists! Any ideas wht is going wrong?

PS I am having the problem when my desktop resolution is 1024x768 and the game's resolution is higher (eg 1600x1200) and NOT when it's vice versa ( eg desktop @ 1600x1200 and game @ 1024x768)!!! Why????

This is happenning with many applications , so i think it's not the application's fault but my system's.

Another thing: When i log in (graphicaly) to fedora core 2 the resolution is 1600x1200 and when gnome starts it's 1024x768. Any clue?

This whole problem also happens under kde so it's not a gnome bug i guess

Anyone?????????????
