[mythtv-users] Geforce 8600 S-Video Problems

[MaverickTech Lists]

I did an almost identical upgrade to you last weekend.

Unfortunately I ended up in the same situation as you.  After almost 15 
hours solid work on the problem I came up blank, and reverted to my old 
video card.

I also upgraded to Geforce 8600. 

I am using Ubuntu 9.04 now.  And have MythTV compiled locally from SVN 
release-0-21-fixes/

I initially encountered your problems with the resolution stuck in 'low 
graphics mode'.  After reverting to the default proprietary nVidia 
binary drivers in Ubuntu I was able to get the resolution up to 800x600, 
and without errors during the startup.  I had previously been 
downloading and installing nVidia drivers direct from the nVidia site.  
when playing with the official ubuntu drivers, I have been using envy.  
It's a great little util :)

Unfortunately this was only the still the beginning of my odyssey.

It appears that all support for overscan adjustment is gone from the 
nVidia drivers in linux, for recent nVidia cards.  No matter what 
version of driver I tried I could not adjust the overscan to bring the 
image back within the confines of my TV/S-Video display.  The image so 
so far out of the park that without some adjustment of overscan it was 
not usable.  The overscan sliders are missing from the nvidia-settings 
program, and any overscan related entries in xorg.conf seem to be 
ignored these days.  Well, ignored on recent gfx cards.

I tried nVidia drivers  from 180 series, 177, 170, and back as far as 
96, but got no success with overscan.

My system is running my new motherboard at the moment, it's been 
upgraded to 9.04 ubuntu, but the gfx card has been reverted back to my 
old card.  Seems unless something changes, my next upgrade will have to 
be a new TV.

That's a brief account of my battle with the nVidia overscan problem 
last weekend.  Happy to answer further questions if it will help.  Would 
also welcome having it pointed out if I missed something stupidly 
obvious during the install ;)

Regards,
