How do I make my FC3 system use a resolution of 1440x900? I am not sure how to edit the xorg.conf file.

As a follow up, I checked my Xorg.0.log and when it mentioned the 1440x900 resolution, the log showed that the width was too big for the virtual size. So I guess the question now is how do I get the virtual size increased?

in xorg.conf u 'll find something like this

Why don't you put your resolution in there?

I'm not sure if your system supports this resulution.

Here's my xorg.conf file:

# 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.

# To disable the XKEYBOARD extension, uncomment 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"

# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"

# If you'd like to switch the positions of your capslock and

Here's the entry in the log that is causing me trouble:

(II) NVIDIA(0): Not using mode "1440x900" (width too large for virtual size)

I don't know if that helps but as far as i can see you have installed Nvidia's 3d accelerations drivers (module "nvidia")
u should dissable dri module:

Read the nvidia README file!!!

I realize this is an ANCIENT thread and that I'm crossposting, but I just lost -- literally -- days on this problem. I finally found a solution and I post this reply for people with the same problem I had who may find this thread. My issue was using Sabayon (though not OS specific) Linux with a Polaroid tla-01911c 19-inch HD television as a monitor attached via VGA cable to my nVidia GeForce 6200 NV44a AGP video card and not getting the proper set of resolutions available to the "monitor". Studying my /etc/var/Xorg.0.log showed me that the card could not get EDID info from the monitor. (Let's see how many more keywords I can add)

What I finally did was set a "modeline" (not just "modes" but actually "modeline") so that EDID info was not necessary. Turns out it's an ancient method that still works.


The link below is what got it working for me:

Hope this helps the next poor fellow looking to get something other than 4:3 resolutions on a 16:10 screen!




FWIW, my /etc/X11/xorg.conf (may not be 100% correct, but it's working for just right now -- I'll mess with it later)
