I'm new to Linux and just installed Ubuntu 12.10 on my HTPC that I just put together.
It has a Z77 chipset with a Intel i3 and Intel 2500 graphics. I'm having an issue with overscan. I have an older Dynex 42inch tv that does not let you turn overscan on or off. I can't see the top, bottom or sides of the screen due to this and I've been trying to fix it.
I've seen some stuff about modelines, and kernels, but I'm so new to this, all I'm able to do is open the terminal.
Can someone tell me what to do step by step to get to a point where I can adjust the overscan?
