[mythtv-users] Ahh - Evil xorg and modelines

Damian,

I have been watching your thread since it started the other day.  I am 
new to MythTV so I have been reluctant to respond, however I have been 
working with X for many years.  In the old days, configuring a plain old 
video card and mouse was this hard all of the time, they have come along 
way.

One this I noticed that I thought I would point out is that two 
individuals noticed that you are not specifying the the _identical_ 
resolution and frequency in both the modeline and the screen section of 
your config file.  You dismissed (graciously, but all the same) both of 
those points by saying:

"...don't think that's the problem. I've tried every combination of lots 
of different modelines and tried only specifying one, specifying two 
etc. nothing seems to get me anywhere."

and

"I'll gladly try again, but I've tried each and every one of those 
modelines."


While it me be me who is mistaken now (have been several times), your 
responses refer to how many different modelings you have tried and I can 
see all of those commented out in your config file.  However, neither of 
your response or any of the config files you posted addressed the fact 
that you still do not have an _identical_ (character for character) 
resolution and rate specified in your modeline and your mode variable in 
the screen section.

Again maybe you have indeed tried that and it did not help, however none 
of the responses or postings of your config file represent that you have 
correctly specified what was asked in the two previous emails.

Several people who have posted success with there config files have:

"1024x768_75" in both the modeline and the screen section.

I hope this helps, I know your frustration

David

I'll gladly try again, but I've tried each and every one of those modelines.

The config you have posted every time contains a screen section 
configured as such, with not rate included:


Section "Screen"
 >     Identifier     "Default Screen"
 >     Device         "nVidia Corporation NV34 [GeForce FX 5200]"
 >     Monitor        "BenQ W100"
 >     DefaultDepth    24
 >     Subsection "Display"
 >             Depth       24
 >                 Modes       "1024x768"
 >     EndSubsection
