View Full Version : Nouveau and VBlank/Vsync

9th April 2011, 12:50 PM
Trying out Fedora 15 with Gnome shell and loving it right now.

Just one big problem, the binary Nvidia drivers cause the "Activities" animation to be really, really choppy. Everything else is fine except that.

I'd be happy using the Nouveau drivers if only I could get VBlank/VSync enabled. It's easy with the Binary driver, but with the Open Source one I need to add GLXVBlank to xorg.conf I think? Thing is I don't have an xorg.conf, and from what I can work out it's better to use smaller split .confs for only the settings you need to manually adjust, that are stored in xorg.conf.d.

Anyone know what I'd have to add to a file to get vsync working with Nouveau? It's kind of a deal breaker if I can't.

Thanks :)

No one have any ideas? :(

Screen tearing is way too much when trying to watch a video. Why would they not enable this feature by default? I don't understand...

how about here http://ubuntuforums.org/showthread.php?t=1446367 where it talk about setting vsync in compiz. Or here http://www.phoronix.com/scan.php?page=news_item&px=ODcwMw

Having exactly the same issue. I think that the default has been changed in the very latest driver upstream but that hasn't fed down - and I guess won't for this release.

So.... In the meantime how do we change this setting without breaking everything - I made an attempt but then GNOME shell didn't load right at all.
