Hey there,<br><br>I've got a Mythtv frontend running on a laptop and I have just hooked up an external LCD monitor. After some futzing around with xorg.conf and Kubuntu's system/display gui I have what I believe to be "cloned" operation. That is, the external LCD just has whatever is on the laptop screen albeit a little stretched horizontally. The problem occurs after I start Mythtv. After starting Mythtv AND subsequently selecting live TV, the external display is shifted downwards such that there is a black (empty) band across the top. (The gui is fine before switching to live tv). Furthermore, after exiting Mythtv, the external display stays in this undesirable state.
<br><br>Does Mythtv change settings in xorg.conf? Or, can this be dealt with by using some of the options in Myth's appearance/screen setting? I'm worried about messing with those b/c the problem persists after exiting Mythtv.
<br><br>Thanks for any help/ideas/links. I include some details below. <br><br>- Blaine<br><br>Some Details<br><br>* The frontend is running on Kubuntu Gutsy<br>* The external monitor has a non-standard resolution (1366x768) for which I followed
