SOLVED - Monitor resolution less than stated in xorg.conf

[Snowhog]

This is from my xorg.conf file:

As can be seen, I have a max resolution of 1440x900, which was selected originally during setup configuration from the list of available resolutions.

In System Settings | Monitor & Display, it reports a setting of 1280x800 (the slider bar is max'd so, I could only change it to a lower value).

My question is, why? I know that the running resolution is in fact, 1280x800. I know that, because I've taken full-screen snapshots, and the resulting image is sized as 1280x800. How do I get the full 1440x900 screen resolution that has been properly identified and set up in xorg.conf?

Thanks Rog131! Checked, and did not have this package installed. Just installed it. Ran sudo 915resolution -l and got:

Modes 66, 67, and 68 contain my maximum resolution for my laptop. I'll read through the rest of the cited post and see how things go. I'll post back when I'm finished.

Yours was a very helpful response!

Success!

I now have my system running with 1440x900 resolution. I'm so pleased! 8)

Following the info in the post at http://ubuntuforums.org/showthread.php?t=351647, and with a few trials (and errors ), I finally got things straight.

What I finally ended up doing, was to 'patch' my resolution setting to mode 30 as the info in the post said to do: sudo 915resolution 30 1440 900 32
Then I just restarted the system. Just like that, my screen resolution is running at 1440x900, verified both by checking the Monitor & Display settings as well as taking another full-screen image and checking the file image size: 1440x900.

Man am I one happy camper. This removes one more item from my list of 'not quite right things' with my Kubuntu installation on my laptop. Once I, or someone else, can figure out what needs to be done in order for me to gain accesses to my PCMCIA harddrive, then my list will be finished (at least, finished with all that I have tried to utilize on the laptop.).
