I have a Dell Latitude D620 laptop running Fedora 10 with an Intel 945GM graphics controller. My display is configured as an "LCD Panel 1440x900". I would like to have that resolution, but system-config-display offers 1024x768 only.
Try:
$ xrandr --output LVDS --mode 1440x900
If the driver complains about unknown mode 1440x900, execute
gtf 1440 900 60
(the syntax is gtf horizontal vertical refresh_rate) that will give you a modeline as output
for example for 1280 1024 85 (my external monitor) the modeline is 1280x1024_85.00 159.36 1280 1376 1512 1744 1024 1025 1028 1075 -HSync +Vsync
Note the first 1280x1024_85.00 is the name of the mode, the rest are some parameters the video driver needs to handle the mode correctly.
Then execute the following: xrandr --newmode <modeline> xrandr --addmode LVDS 1440x900_60.00 xrandr --output LVDS --mode 1440x900_60.00
Replace numbers if necessary. This works for me. My system-config also doesn't display the right modes for my monitors. I'm not sure about automating it (someone else will surely chime in); I execute something similar in a script manually after I log in to get my dual head display to my liking.
