My resolution is defaulting to 1024x768, my laptop's screen is 1280x800.

The gpu is Intel GMA 965, I have made sure the proper display driver for it is loaded, also set my display type as 1280x800 lcd.

In the display settings when I try to change to 1280x800 it says

"Display settings changed

You need to log out and restart the X server for the changes to take effect.
Configuration was written to /etc/X11/xorg.conf, original configuration was saved as /etc/S11/xorg.conf.backup"

So I have logged out, restarted, etc. many times. I read on an older thread to try deleting the xorg.conf file, I did that too and have no results, when I boot back up there is no resolution change.

Can anyone help?

I had a similar problem on fedora or ubuntu can't remember. Either way I think it is more of a gnome issue. What we had to do was change the resolution in two different places, one was under the administration submenu from the system menu, the other was under the personal submenu or some such, I'm sorry its been a while since i've used gnome I can't remember the specific names. Either way they need to agree so I would suggest poking around in both those menus. If it doesnt work post back here I'll go find the old computer and check.

I had this problem on Intel hardware also, that was a Sony Vaio laptop. I tried Ubuntu on that laptop and it worked like a charm. So a friend of mine suggested using the Ubuntu Xorg.conf file in CentOS. I just copied it right in there and overwrote the original one, then re-booted. First there were some ugly screens and error messages asking me if I wanted to configure the Xorg file, I said yes, kept saying yes to a couple of other error messages, and it rebuilt Xorg.conf correctly, with a perfect resolution. The reason that worked is apparently Ubuntu and CentOS use very similar Xorg files, so Cent was able to rebuild it. So if you can get a copy of *buntu, you could try running that, and if it has no graphics issues, maybe you could use its Xorg.conf file. In any case, good luck getting it straightened out.

Try the following : Hopefully will work out.

rm -rf /tmp/.X*
service xfs stop
service gpm stop
system-config-display --reconfig
< Change the resolution and select the monitor >
service gpm start
service xfs start
logout from the user
and login you will be using the latest resolution.


Hope it will work...
