[mythtv-users] OT - How to find what is overriding my DPI setting

[Jeremy Jones]

Some Background:

I have an older widescreen plasma with a native resolution of 1024x768.
 Yep that means I have 'non-square' pixels.  I am using nvidia proprietary
driver version 319. My Distro is mythbuntu.  To make my videos display
correctly in myth I have to set the DPI in xorg.conf to "48 x 64". This
setting is being read, because it tells me so in Xorg.0.log.

I had this problem previously with this same computer hardware / TV /
MythTV setup. Last time another user pointed me to the lightdm.conf file,
where the DPI hardcoded.  That's not the case this time.  What changed? I
changed AV receivers and the sound over hdmi would not work after a period
of non-use. In my attempts to fix this I installed different nvidia
drivers, and subsequently screwed up X.

I now have X working again, but I'm not sure what all I did in my attempts.
 I do know I did a clean install of the nvidia driver 319.  I also fixed my
sound issue.  Anyone having that issue I can help now.

The question:

I can't find what is overriding my dpi setting.  How do I track that down?
 I've looked at every config file I could find and every log file that I
could find.  I've even starting trying to go though the logic in some
startup scripts.

I posted my logs here:  http://pastebin.com/npLtTbC8 , in case anyone wants
to take a look.

Thanks for any pointers as I am exhausted from looking.

Jeremy
