X Windows Question

[leland sindt]

Hello all,

I am posting here because I am looking for a local (KC area) X resource. 
I am currently in the final stages of building a MythTV HDTV PVR. This 
is the first Linux box that I have built that is not headless. (read: 
usually I do not work with X.) Long story short, I can get the system to 
output to a standard monitor without issue (X does a fine job of 
determining the proper resolution)  However, when I attach the system to 
my Toshiba HDTV (via DVI) I can only get it to output 800x600 (Image 
falls off the screen) or 640x480 (image does not fill the screen). At 
this point it is my understanding that I need to build a custom modeline 
but for the life of me with all the reading that I have done I cannot 
grasp the concept. 

If you think that you are up the the task and interested, please let me 
know.

On another note, I would be interested in attending a meeting, but 
chances are I will be out of town mid week as I travel for a living. But 
if I happen to be in town I look forward to attending.

Thanks.
