[mythtv-users] New video card crashes PVR-350 card

[Eggert Thorlacius]

Thanks for the suggestions, guys.

I tried switching to the nv driver and the conflict is now gone, so
presumably it was a bug in the nvidia driver.
However, I can't get the nv driver to output in widescreen (1280x768),
only in 1024x768 mode.  If I try using widescreen, I get a garbled
display, and no modeline tweaking seems to help.
My current theory is that the driver is ignoring my modelines because
it can read EDID data from the TV, but that the EDID data is
incorrect.  The nvidia driver had a IgnoreEDID option, but there
doesn't seem to be one in the nv driver.  Does this sound plausible or
am I barking up the wrong tree here?

Here is the relevant part of /var/log/Xorg.0.log:
