1280x1024 @ 86Hz is the default in Dapper but gives an unquiet display. I'm sure my 19' monitor should be Res:

1024x768 but i can't change the defaults in Screen Resolution.

Is this a software prob ? What should i do?

Rather strange that you

Rather strange that you don't have the native resolution, but it is possible to change that.

You will have to edit the /etc/X11/xorg.conf file. To do this open up a terminal such a 'Gnome Terminal' and type:
sudo gedit /etc/X11/xorg.conf
This will fire up the text editor with the relevent files and permissions. Scroll down the file and you will find a part which looks similar to:

Section "Screen"
Identifier "Screen0"
Device     "Videocard0"
Monitor    "Monitor0"
DefaultDepth     24
SubSection "Display"
Viewport   0 0
Depth     16
Modes    "800x600" "640x480"
SubSection "Display"
Viewport   0 0
Depth     24
Modes    "1280x1024"

Edit the line beneath 'Depth 24' to Modes "1024x768" "1280x1024". Now save the file and quit the editor, then restart your X-server (this is the software which lets you have graphics) with Ctrl+Alt+Backspace. When the X-server restarts you should have an option for 1024x768 in your Screen Resolution options.

If you are still having problems please post back and we'll try to help Smiling

Yep, dylunio's solution

Yep, dylunio's solution should be followed because it will apply the new settings permanently.

To immediately switch resolutions you can also use the "Screen Resolution" configuration tool found in system menu.
