[mythtv-users] No xvideo with an nvidia 7950

[Richard Horton]

Sorry about the html.  I will use text from now on.

I am fairly certain that I am using the binary driver, because I had to get
it from Nvidia (it's not the one that came with Linux) and it downloaded as
a .run file, and installed from there.  (The .run file is just an install
script, not a build script, right?).
Having said that, the installation procedure told me that it had to rebuild
something as there wasn't an appropriate build available at the source
location on the web for my architecture (x64).  Does anyone think that could
be a problem?

Cheers,
Richard.

Hi there,

Could I possibly trouble you by asking that you post in plain text?  
When I received your email the text displayed very small on my system, a
size not conducive to reading with my blurry early-morning eyes, and it was
an inconvenience to reach for the keyboard & increase the font size. If you
add mythtv-users at mythtv.org to your Outlook address book then I think there
is an option to "send to this recipient only in plain text".

I _think_ this indicates that your graphics card drivers don't support
hardware acceleration.

Have you installed the binary nVidia drivers?

As Mr Wilson observes "if you didn't know about the binary nvidia driver, I
can almost guarantee you're using the open source nv driver, which is
utterly craptastic ..."

Sorry I can't help with your other problems.
