Nouveau graphics anomaly with update to kernel 3.3.0-4.fc16.x86

Hi all

I'm very new to Fedora, so please be gentle with me.

I installed F15 yesterday from a CD, and was advised today on these forums to upgrade to F16, which I did. After a few problems, I ended up with an install that didn't work that well, so did a

su -
yum clean all
yum update

and ended up with an install (over kernel 3.3.0-4.fc16.x86 that worked except that had an overscan on my monitor (which is a 22" widescreen HDTV) with no easy way of compensating for it.

As the previous install (over kernel 3.1.0-7.fc16.x86) didn't have this problem (nor did F15), I tried booting with the 3.1 kernel, and hey presto, no overscan. And TBH, it's working very well!

So my question is this: does anyone know why it's not OK with the 3.3 kernel, but works OK with the 3.1 kernel? And if so, is there a fix, or do I wait until the next kernel comes round? (Actually, that's 3 questions!)

Here's my gear, in case you need to know:

Re: Nouveau graphics anomaly with update to kernel 3.3.0-4.fc16.x86

Sounds like https://bugs.freedesktop.org/show_bug.cgi?id=47846 or https://bugzilla.redhat.com/show_bug.cgi?id=806091. I've posted a patch in the latter which provides a workaround.

BTW, the reason your display works with kernels prior to 3.3 is that HDMI InfoFrame support (which is what carries audio data, among other things) was added to the nouveau driver in that version.

Hi thanks for that.

However, since posting this, I bit the bullet and downloaded the nVidia driver which works well and has overscan compensation on the front end.
