Hello Everyone,<br>
<br>
I have been asking this question on Linux Questions and I have
received some advice from one kind soul but nothing seems to be
working. I was thinking that people here might be more accustomed to
dealing with this type of issue. Below is a cut and paste of my
original post on Linux questions. If you follow the thread we've
tried the follow:<br>
<br>
1) adding "Modes "1600x1200" "1280x1024" "1024x768" "800x600"
"640x480" to xorg.cong" <br>
2) removed and blacklisted the nouveau drivers<br>
3) update grub<br>
4) update the initramfs<br>
5) on my own I changed settings in the xorg.conf to HorizSync
15.73 - 67.5<br>
VertRefresh 23.98 - 60.00 based on information I got from my
manual.<br>
6) I also tried to create a new mode in xrandr that I got from
<a class="moz-txt-link-freetext" href="http://www.mythtv.org/wiki/Modeline_Database">http://www.mythtv.org/wiki/Modeline_Database</a> but no joy.<br>
<br>
As always thank you for any help you can provide.<br>

<big><u>ORIGINAL QUESTION:</u></big><br>
I've just loaded Ubuntu 12.04 on a new(used) HTPC which I have
hooked up to a Panasonic TV (this is to be used as a MythTV
frontend). The TV's max resolution is 1024x768 but the option isn't
available in X-server or the Ubuntu display controls. It is
currently set at 1280x720 and subsequently the controls are not
completely visible on screen (overscan) making it very difficult to
work with.<br>
<br>
The output graphic controller is :NVIDIA Corporation C77 [GeForce
8200] (rev a2) (I don't know if you need any more information).<br>
<br>
I tried the below (sorry I forgot how to get it into the little
scrollable box) taken from the following website (<a

target="_blank">http://ubuntuforums.org/showthread.p...ar#post8595940</a>)
but as you can see I came to a dead end.<br>
<br>
Any help anyone could provide would be greatly appreciated.<br>
