Unable to get 1440x900 resolution


Best Regards Team:

This's on a TOSHIBA Notebook P35-S609 with dual OS (Windoze XP & RH FC3) Under Windoze the default resolution is 1440x900 with ATI Mobility Radeon 9000. After installing FC3 the max resolution that I'm able to get is: 1152x864.

Using the GNOME "Displasy Settings" program, in the "Hardware" tab, the monitor choosen is: "LCD Panel 1440x900" and the Video Card: "ATI Radeon Mobility 9100IGP"

I already edit the xorg.conf file for the 1440x900 resolution, but after rebooting the new resolution is not changed and is not displayed in the "Display settings" or the "Screen Resolution Preferences" program..!!
Here's the conf file:

Quote:
# Xorg configuration created by system-config-display

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"

# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# 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.
RgbPath "/usr/X11R6/lib/X11/rgb"
FontPath "unix/:7100"
EndSection

Section "Module"
Load "dbe"
Load "extmod"
Load "fbdevhw"
Load "glx"
Load "record"
Load "freetype"

Section "ServerFlags"
Option "AllowMouseOpenFail" "yes"
EndSection

Section "InputDevice"

# 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"
#

Your issue is probably related to the horiz. and vert. frequency settings.

Do you know if those numbers are actually correct for that display?

You might get that info from Toshiba or just do some googling.

I had a similar issue with a dell laptop and did some searching and found the info I needed.
I'm not sure it was the actual specs for that display, but it worked.

1440x950?

You sure it's not 1400x1050, that is a pretty normal resolution for a laptop. I't is a sure thing, laptops allmost allways use xga, sxga+, uxga, wxga, wsxga, wsxga+, wuxga Is this a widescreen laptop? ou should enter windows and write down the resolution it uses.

do a search in the forums here for 1440x900 since your post others have posted and solutions have been reached, I just fixed this myself and am finding unanswered threads liek this one. the key is to add a 'modeline' to your monitors section of the xorg.conf file.
