So, about that “working perfectly”
Well, I have to admit that I was blinded by love for my laptop. But when I said that 1920×1200 was working perfectly on my Inspiron 9400, I was wrong. I didn’t even really check - it just looked sooo good.
But then I went to take a screenshot of the next generation of SAGrader, running for the first time under Linux, and noticed a strangely… smaller screenshot than I expected. About 320 pixels smaller, horizontally speaking.
To make a long story short, to get 1920×1200 instead of 1600×1200, I needed to add a Modeline to X.org. Add this in your Monitor Section:
# 1920×1200 @ 60.00 Hz (GTF) hsync: 74.52 kHz; pclk: 193.16 MHz
Modeline “1920×1200″ 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync
And make sure that your Screen section contains an entry for “1920×1200″. Then restart your X server - viola! - instant screen real estate.
Edit: I also needed the 915resolution package installed, but I didn’t have to edit any startup files.
