NVIDIA Posts Latest PRIME Sync Patches On Road To Better Support

[Stebs]

Slightly offtopic, but since there should be some Optimus-Users watching this...:
Is it possible to somehow use Nvidia 980M with Maya 2015 on an Intel/Nvidia Optimus Laptop, where you can not disable Intel in the Bios?
It's not for me, but a friend of mine, so I have no exact error descriptions at this time, just want to know if it is possible at all, and where to start reading.

Apparently he has installed bumblebee, that works so far, but Maya 2015 crashes when run with optirun...
So, are there workarounds, or is it at least possible to always use the Nvidia GPU?
(He uses latest CentOS)

Does DRI_PRIME work with the nVidia proprietary driver?

nope!

Excellent news. Hope this gets merged soon and that the bug affecting xorg-server 1.18, nvidia proprietary drivers and this configuration gets fixed because it is currently broken: https://bugs.archlinux.org/task/47151?project=1

Probably unrelated, but tearing became unbearable with latest plasma 5.5 on a laptop with both intel and nvidia graphics. However the simple solution was to disable kwin's "smart" refresh and force full-screen repaint.

Apperently, you could try and enable DRI 3 for the intel GPU ( https://wiki.archlinux.org/index.php...e_3_.28DRI3.29 ) . I had enabled mine ( Intel HD Graphics 4000) for the past few weeks. No tearing whatsoever using Kwin on Intel unless I disable vsync.

I have the GTX-960M to be a good balance between performance and $$.
I have a Sager NP7255 (Clevo 155RD).

As far as I know, the tearing isn't fixable if you're on nvidia in your optimus setup. If you're on intel, it's fine, but on nvidia there's no vsync or synchronization. It's why I switch to intel when watching a movie

Also, thanks Michael for covering the pull request I sent you

There may be no vsync, but having nvidia selected as primary and forcing full screen repaints, there's no visible tearing anymore. Keep in mind this a work laptop, I don't watch movies.

Probably not the best option for gaming, but for my work laptop there are no downsides (that I have noticed so far).

Edit: Scratch that, the tearing seems to come back between reboots. Now trying adding a couple of environment variables instead (sthis supposedly works better).
