Linux Modeline for full-screen MBP goodness

Hey folks,

Here's what I did to get 1440x900 full-screen resolution working with a Linux guest OS (CentOS 5, to be exact). I manually edited the xorg.conf file, and added the following Modeline to the Monitor section:

Modeline "1440x900" 108.84 1440 1472 1880 1912 900 918 927 946

Then in each "Display" subsection of the "Screen" subsection, I added "1440x900" (including the quotes) to the list of resolutions on the "Modes" line. I put it first.

Things worked like a charm after that!

I have attached the entire xorg.conf file to this post for you. Just use it to replace /etc/X11/xorg.conf (though I would back up your old one just to be safe).

Autodetection didn't work?

No modeline was necessary for Xorg 7.0 on Debian; specifically package xserver-xorg_7.0.14. The 1440x900 mode and matching modeline was autodetected by the VESA driver. I'm not disputing that you needed a modeline, and your modeline is obviously helpful to others based on the replies in this thread, it's just that I'm curious that the autodetection didn't work for you.
 
Believe me, I'm curious too. Which monitor type did you select? I wonder if that makes a difference. I did the 1440x900 LCD panel.

I chose the VESA driver, ensured that the ddc and int10 modules were loaded, clicked 1440x900 in the resolution list, and then chose Simple -> 17" for the monitor selection. Worked first go.
 
OK, you're above my pay grade now. I don't know how to insure that the ddc and int10 modules are loaded.
 
Ok, found by myself.

Under fedora core 4.
I just used the visual tools: System Settings -> Display / Hardware, Monitor Type: LCD Panel 1280x800

then the screen resolution can be changed to 1280x800.

cool!
Not getting a great performance in full screen though.

you need to have appropriate permissions to write to xorg.conf; try "sudo [editor] xorg.conf" and you should be able to save. If you are in the sudoers group. Or log in as root if you still run that way...
