PS3-Ubuntu screen resolution problem

[Ownagemuffin]

Hello interwebs,

As a school project, I have decided on the topic of obtaining a PS3 (the old fat one) and install Ubuntu on it and turn it into a home computer. I am new to Ubuntu as a whole, but after following instructions from the internet, I got Ubuntu version version 9.04 installed on my PS3. Everything on it is running perfectly fine, except my TV crops the screen size. I tried changing the resolution using system-preferences-display. But I can't resize the window (to click the accept button) so that changing the screen resolution is impossible. This is really affecting the way I am using this as a whole as I can only view half a window when I open up anything and some buttons (the most crucial ones) are always out of reach. I read that you must change some sort of coding in the system files to resize the entire linux, but I am new to this and I hope that someone can guide me through this.

Thanks

My TV is a Philips 37LB1R-TH

you can usualy use tab until the button is highlighted (or you're guessing it is) and hit space bar to select the button. if you hit the right one, it should change the resolution.

this is caused by overscan, you need to generate xorg.conf with proper modelines to adjust for the overscan

X.Org Wiki - FAQVideoModes
check this out for one, i would do some googling on your tv model and see if someone already has an xorg.conf that works for it

So i just find the xorg.conf inside the system files and change the values right?

xorg.conf may or may not exist, if it doesn't you need to log into console, and stop X server, and use sudo Xorg -configure command to generate one

If you are running vanilla ubuntu, to stop X server you run sudo /etc/init.d/gdm stop command

by the console you mean the terminal right?

I entered it into the terminal and I got the following error:

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.x0-lock and start again.

What does this mean?

I also did find xorg.conf in my files, but opening it with the text editor shows nothing, what is going on?

no, i meant the console

you can access it by pressing ctrl+alt+f1
