Linux Problem Screen Resoultion

[Matus]

I installed Ubuntu on a Toshiba Satellite A25-S207 everything seems to work fine, but the screen resolution is a prob. It has like this small window for the interface and along the sides all black. I googled stuff and came across xorg.conf modifications, it only hit the login screen to be fixed. but as soon as you log in its the same problem again. The original xorg.conf file is like this , and I modified teh section in color way below that fixed the login screen, but teh rest still not up, anyone got ideas how to tweak this?

Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
Option "XkbOptions" "lv3:ralt_switch"
EndSection

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
EndSection

Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizEdgeScroll" "0"
EndSection

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Synaptics Touchpad"
EndSection

Fixed Section Monitor to this:

Section "Monitor"
Identifier "Configured Monitor"
Option “DPMS”
HorizSync 28-60 # horizontal refresh frequencies
VertRefresh 43-60 # vertical refresh frequencies
EndSection
