Make sure if the frecuency of your monitor is right setting in your /etc/X11/xorg.conf
vertical refresh and horizontal refresh, and the resolution have the option that you trying to change.
The frecuency of your monitor is in the manual of it.
Hope you understand me, and can fix that

PD.: sorry about my english, please forgive me

in the /etc/X11/xorg.conf I dont find a choice for horizontal and vertical refresh : typical:

Section "Screen"
 Identifier "Default Screen"
 Device "ATI Technologies Inc RV280 [Radeon 9200 SE]"
 Monitor "PKB MAE220W"
 DefaultDepth 24
 SubSection "Display"
  Depth 1
  Modes "1680x1050" "1600x1200" "1440x1440"

In the "Monitor" section of your xorg.conf, add the following line:

Modeline "1920x1200" 154 1920 1968 2000 2080 1200 1203 1209 1235

and see if it changes it.

Thanks for the answer!

My knowledge to system problems is not great. I have altered the file. but I do not manage to get the permission to save the file, (I am the adinistrator)

In any way, my PC have now booted up two times with the ability to change the resolution to 1680 1050! Maybe it has something to do with my screen, mouse and keypad switch (Belkin) to my Siemens combined Ubuntu/Windows computer (for the last to boots my combined Ubuntu/Windows computer has been shut down). When I now booted combined Ubuntu/Windows computer. I did not have all the choices og different resolutions. So at last I think it must be the Belkin svitch causing the problem.

I will tell you if I changes my opinion about that later.

Thanks so much for the help! (I was not able to save the xorg.conf file, so I will stuggle more along with Ubuntu tomorrow)

Joho :)

You can sudo dpkg-reconfigure xserver-xorg and follow the instructions. At some time it will ask you to choose between possible resolutions to be available.

Massimo Forti (slackwarelife) said : #9

To change some file configuration in ubuntu/kubuntu you can use the comand "sudo" on a shell. For example to change your xorg.conf in Ubuntu 7.04 you must do:

open a shell

in a shell edit:

$: sudo gedit /etc/X11/xorg.conf

inset the password asked

thanks
