I am trying to get a better resolution on my laptop. The reason why is because I have a widescreen laptop display. I generated the correct modelines for 1440x900 and 1280x800 and put them in the XF86Config-4 file. In the XF86Log, here's what it says:

(II) VESA(0): Not using mode "1440x900" (no mode of this name)
(II) VESA(0): Not using mode "1280x800" (no mode of this name)

Here's my XF86Config-4 file:

Please help me to get it to work. I have the same problems with the nvidia drivers.

You've named then two diffrent things.

1440x900@60 -> 1440x900

The names don't match so there is no modeline called 1440x900.

Change:

Subsection "Display"
Depth 24
Modes "1440x900@60" "1280x800@60" "1280x1024" "1024x768"
EndSubsection
EndSection

Or change the mode line to 1440x900

I did what you said and it still didn't work, the log still says:

(II) VESA(0): Not using mode "1440x900" (no mode of this name)
(II) VESA(0): Not using mode "1280x800" (no mode of this name)
(II) VESA(0): Not using mode "1280x1024" (no mode of this name)
(--) VESA(0): Virtual size is 1024x768 (pitch 1024)
(**) VESA(0): *Built-in mode "1024x768"
(**) VESA(0): Built-in mode "800x600"
(**) VESA(0): Built-in mode "640x480"

Does the vesa driver need to be configured?

Nevermind, I went back to see if the nvidia drivers would do a better job and like magic they did. I now have a 1440x900 rez! Thanks a lot!!!

Glad its working.
