Increase resolution in Ubuntu

In Ubuntu I go to Computer > System Configuration > Sceen Resolution, but the highest I can choose is 1024x768. In Windows I would run 1280x1024 fine with a real low refresh rate because I have a 17" CRT. I also remember during setup it asked me what I wanted X to use for resolutions and I tried to tick 1280x1024, but pressed enter so installation continued. So does anyone know how to increase the resolution to 1280x1024 as 1024x768 is really uncomfortable.
 
If you're using whoreme you're using x.org and should edit something like /etc/xorg/xorg.conf. If you're using warnme you're using XFree86 and it's in /etc/x11/XF86Config. The /etc/xorg might be /etc/x11, I'm not positive.
 
just had to do this with my 2005FPW. google and you will find the answer...Mine involved adding a modeline to the /etc/x11/XF86Config file n0cmonkey mentioned.

google "resoultion modeline and xf86config" for starters and see what it says
 
Thanks, it was /etc/x11/XF86Config-4. but I cannot edit it. I am guessing I need to be logged in as root? Anyone know what the default root pw is? I don't remember setting a root pw.

Yes, I do need to be logged in as root, but do you know the default root pw? I went to the terminal and types "su" to become root, but I do not remember setting a root pw. All I remember is setting a user pw and I tried that as the pw for root and it does not work. So do you know the default?
 
I enabled the root pw by using sudo passwd root, then I logged in as root by using su, but I still cannot edit the file. I opened it up and I try to type in 1280x1024 so it looks like this

SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"

When I try to change it I cannot type. I don't know if this helps, but I am using gedit to edit the config file.
 
Are you running gedit as root?

You'd probably be better off editing the file from a console with nano/pico/vi.
 
It may have been defaulted to blank.

By default Ubuntu disables the root account and runs no servers, not even ssh, so good luck.

I enabled the root pw by using sudo passwd root

There's no reason to do that.

Use sudo instead, I believe it'll use your user's xauth info so you won't have to do anything funny, just 'sudo gedit /etc/X11/XF86Config-4' .
 
ubuntu is setup for sudo...

next time you want to edit a file type "sudo gedit filename"

it will prompt you for your password.
