So how would a person setup their xorg.conf file so that it will ouput
either 1080i OR 720p depending upon the source material? My TV
will do 1080i and 720p, so I wouldn't necessarily want to force it one
way or the other.<br>

from SVN on Ubuntu outputting component out via a fanless Nvidia 6600. Reading
some old posts from Jarod and others, I was able to output to my TV (which
accepts 1080I, not 720p on a 4:3 screen) with the line in my xorg: Option
"TVStandardard" "HD480i" No modelines required. <br><br>While this works great,
it obviously isn't HDTV which was my primary purpose for MythTV. (Can't wait to
sell my Tivo!). When I add the line Option "TVStandard" "HD1080i" I get a small
desktop on what appears to be a 1080i resolution. I can see that Nvidia is
outputting a wide screen resolution but the desktop is significantly narrower
and shorter than the NVidia output and is centered in the screen. I have tried
the Windows/Powerstrip route and gotten modlines that should work but don't seem
to help. Also, when MythTV kicks into watching a show under this mode, the
system freezes and requires a reboot. <br><br>Second question. Considering that
I have a 4:3 HDTV (16:9 didn't fit in my entertainment center but I will be
buying a front projection in the near future), will 1080i output ever be able to
fill the screen for shows that are 4:3? Probably doesn't matter since those
shows aren't HDTV anyway but I don't think I can change Xorg.conf from one mode
HD480i to the other HD1080i on the fly. Or can I? <br><br>Sorry for the newbie
questions. BTW, I appreciate all of the folks that respond on this and other
forums. I took a little different route setting up my first MythTV system on
Ubuntu with a Fusion 5 Gold card and 6600 component output. While this is
probably trivial for some folks, it was a great challenge (and a ton of fun) for
someone that has never worked on Linux before. I had many, many problems all of
which I was able to solve (except this one) by reading through this and other
forums. For the active posters/problem solvers: Thanks! Not to mention the
developers! </font></span></div></td></tr></tbody></table></span></div>
</blockquote><br>For anyone trying to do 1080i component out on
NVidia 6200 or 6600, I struggled to get this to work so thought I'd
post my solution for other's benefit. Most posts in the past suggest
to use tvstandard HD480i (not HDTV) when using component out directly
from a 6200 or 6600. I was able to get HD1080i to work on my 6600 with
no modelines by doing the following:
<br><br>Nvidia 7676<br><br>In my xorg.conf:<br>Under device settings:<br><font color="black" face="Verdana,Arial,Helvetica" size="2">Option "TVStandard" "HD1080i" </font><br><br>Under screen:<br>modes "HD1080i"
<br><br>This got me to a full 1080i display with 1080i desktop but X locked up upon playing video. To fix that:<br><br>Open
nvidia-settings and set vsync-to-blank to unchecked (not default).
(could also modify the nvidia settings file directly - I did both but
assume along would work)
<br>Everytime X loads, type:<br>
$ nvidia-settings -l<br><br>The only
problem is that this is still horribly overscanned. Will
probably
play with modelines in the future to see if I can fix this. Have
read posts that say there is no answer short of getting a TV technician
to change the TV. I got the
nvidia-settings -l command from posts on NVNews and they suggest you
need to type that command every time X loads. I also found
that to be
true. People smarter than I am could probably suggest how to get
the
line for nvidia-settings -l to load on every startup. I am still typing
mythbackend, sudo lirc, and mythfrontend everytime I boot my
computer.
Just haven't worked on this yet. The basic instructions didn't
work
for me.
