Resolution Problem in Ubunto 10.04

Could you provide model of graphic card for people who will answer your question.

Can you give the output of:

sudo lshw -C display

I hope its not some crappy SiS or intel thing

After Giving "sudo lshw -C display" command I got this:

Yeah was kinda hoping it wasn't one of those. You will need an xorg.conf to make it use the resolution you wish. You will need to run:

gksudo gedit /etc/X11/xorg.conf

to get write access, you can search the web for sample files to paste in there. You will need to reboot to test.

actionparsnip I opened xorg.conf file its totaly blank. Would you tall me more briefly what should I do for get my choice-able resolution???

the file IS blank by default (It doesn't even exist in Lucid) but your video chip needs one. You will find samples of files on the web.

I'm really a new user of Ubuntu. Is there any software that I can do this easily??

No unfortunately you have a cheap intel video chip so you have to pander to it. Usually displays tell systems what they can do and the system uses this settings. You display is not so you must manually tell the OS how to use the video chip and the display.

If you add this code to the file:

Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
EndSection

Section "Monitor"

Save the new file, close gedit and reboot it may work, you can find other sample files online with some very simple websearching. If you dont get an x server on boot simply run:

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf_old; sudo reboot

And you will get your desktop back, you can rename the file back in then re-tweak til it's nice.

Please HELP! HELP! HELP!
