Unable to set correct screen resolution [intel GMA 4500m chispet]
So, my last resort. I've been working on this for about a year on and off and i've tried to resolve it in both openSUSE 13.1 and, now, in Kubuntu 14.04.1 with absolutely no joy.
My problem is that my Toshiba Satellite C660 - 10T will not display an image on the screen correctly. It is overscanned on the vertical and there is a black border of about an inch in size on the right hand side of the screen. I have trawled and trawled google, man pages and wiki's trying to figure out how to fix it and all i can find is solutions for this issue that work for everyone else but not me.
The problem seems to stem from the operating system misidentifying the physical panel size as 330mm X 210mm at 16:10 (it is actually 15.6" or 345mm X 194mm 16:9) and the driver is therefore ignoring the native resolution of 1366 X 768 and forcing it to 1280 X 800.
I have tried to use xrandr to set a new mode line but when i run
all i get is
All other xrandr commands either do nothing, error or produce screen corruption.
Setting a custom 10-monitor.conf or xorg.conf has also been completely fruitless and i still get the same problem if i try to set the video driver to vesa of fbdev in the xorg.conf.
I really need some help with this! Does anyone have any ideas?
Thank you so very much in advance.

Code:

but I don't know how I'm supposed to post output for commands that didn't have any (which with Linux means they were successful with no errors but I don't need to tell you that). Using LVDS1 instead of VGA1 just cause's --addmode to error not matter what mode I select and that error is already posted, but as i said adding the mode to VGA1 has had a mildly positive effect. The best I could do is post images of the before and after, but I don't have any before images so I settled for posting a description of what happened. If this was in some way the incorrect thing to do please feel free to enlighten me.
