I have the same laptop, and you want to set it to use a custom modeline, I can tell you what you need to change in the X setup... I hope you know a little about configuring X... if not, I can give you more detailed help, just email me personally... anyway, you need a good definition for your laptop as follows
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
HorizSync 40 - 100
VertRefresh 40 - 120
Option "dpms"
Modeline "1440x900" 97.54 1440 1472 1840 1872 900 919 927 946
EndSection
you will also need to get the most recent Nvidia driver for linux... so you can make sure that the video card is running accelerated... get it from here
http://download.nvidia.com/XFree86/L...-4496-pkg2.run
then run that script as root and it will setup the nvidia module for Xwindows
Then make sure the section about your graphics card is as follows :
Section "Device"
# no known options
Identifier "Nvidia Driver"
Driver "nvidia"
VendorName "NVidia"
BoardName "GeForce"
#BusID
EndSection
Also make sure the Screen settings are as follows:
Section "Screen"
Identifier "Screen 0"
Device "Nvidia Driver"
Monitor "Monitor0"
DefaultDepth 16
Subsection "Display"
Depth 16
Modes "1440x900" "1024x768" "800x600" "640x480"
EndSubsection
EndSection
that should do it for you... if you're confused, email me personally at
phil at daviszone dot org
and I can email you the whole config file from my /etc/X11/XF86Config so you can just insert it there, you'll still need to run the Nvidia driver install for the video card... but after that I have beautiful video!
The only two issues I still have with the laptop are that I can use the madwifi driver to startup my built in wireless, but it hangs the machine from time to time and it does all kinds of other odd things, and I can't figure out how to make the grub splash screen readable, of course I know which option is windows and which is linux so I am ok it just bugs me thats all
anyway
hope that helps
Phil
