Ubuntu – Display resolution problem with Sony TV and Intel integrated graphics

displayintel graphicsresolution

I am trying to set the correct display resolution for my Sony TV (KDL-32V2000, native resolution 1366×768) connected via HDMI to my HTPC running Ubuntu 12.04. I have a Intel Core i3-530 and Intel mobo (DH57JG), so no proprietary graphics drivers.

The problem is that I can't get the correct resolution to display on the TV. Initially I only had 1024×768 (or similar) as a maximum resolution, which was not displayed properly. I tried a few steps, including generating an xorg.conf (initially didn't have one) and adding the segment as described in this post regarding this particular TV. I couldn't get this to work, and at this stage have reverted to running without an xorg.conf. Another post suggested upgrading to kernel 3.5, which did give me a 1920×1080 resolution option. This results in the TV cutting off a fair bit of the edges of the screen.

My Dell laptop with ATI drivers recognises the TV screen and works well via HDMI.

Any idea how to proceed?

That is a rather nonstandard looking resolution which might cause some difficulty, my guess would be that you would need a modeline in your xorg.conf for it, I just did some digging on this searching for xorg modeline 1366x768 and found a forum post which looks like it will probably help you out, the question there is also about configuring a mode for a TV.
