how to change resolution in kubuntu 8.04

[Abir]

Please tell me how to change my screen resolution to 1024 * 768. By default, it's 800*600.

I have tried this :

System settings -> monitor & display and found resolution there. But it says u need root access to change settings there.

Your adminstrator password is the one u chose when u installed kubuntu, so use it there.
You can also click "Administrator mode" button in the bottom of the window and type in the password and that should do it.

Well, this did not work. I clicked that and typed password then clicked keep settings. Instead when i restarted the resolution became 640*480.

My graphics card is intel 945 on-board card.

Nope. They did not fix it in hardy

I tried changing xorg.conf but it did not worked or, I don't know actually how to make it work.

Why don't you post your /etc/X11/xorg.conf here - perhaps we can spot the error (no promises...)

Note that this is after reinstalling kubuntu. Because I did not know how to get back to 800 *600.

First off, make a backup copy of your xorg:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

Now feel free to twiddle with the file:

Under "Section Screen", try to add the following SubSection including the Defaultdepth command:

SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
Defaultdepth 24

So that your Section Screen looks like:

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
Defaultdepth 24
EndSection

You probably know that these changes can only be done as root. My preferred method is

sudo vi /etc/X11/xorg.conf

, but

sudo nano /etc/X11/xorg.conf

is user friendlier...

Once you've done it, do a

sudo /etc/init.d/kdm restart

It may work

Re: how to change resolution in kubuntu 8.04

Well, i added that subsection with default depth. Then typed the command u provided. A black screen appears with some texts like restarting kdm.... But it waited for a while so i thought something is wrong and restarted the pc. Now it's still 800*600.

Re: how to change resolution in kubuntu 8.04

Have you now tried changing the resolution in systemsettings? If not, give it a go.

Should that still not work, adjust the defaultdepth in your xorg.file to 16:

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Depth 16
Modes "1024x768"
EndSubSection
Defaultdepth 16
EndSection

And try restarting and systemsettings again.

Other than that I don't know. Perhaps you want to post the output of lspci so we know your video controller.
