Add the jessie-backports repo and install the following:

i965-va-driver=1.7.3-1~bpo8+1
i965-va-driver:i386=1.7.3-1~bpo8+1
libva1=1.7.3-2+bsos1
libva1:i386=1.7.3-2+bsos1
libva-x11-1=1.7.3-2+bsos1
libva-x11-1:i386-1=1.7.3-2+bsos1
libva-glx1=1.7.3-2+bsos1
libva-glx1:i386=1.7.3-2+bsos1


Here I used to get a green screen (not black) when streaming but full sound, etc, etc. Not any issue on the BPM tho... After updating, no more issues.

Please fix the xbox controllers...

Update:
Same issue on a Xbox One wired controller.

Wasn`t working on latest stable, and latest beta still doesn`t fix it.

Haven`t been able to use my Steam Machine for a full hour since purchase. Great troubleshooting simulator

My wireless 360 controller seems to work fine for about a minute, and then it freezes for another minute. Rinse, cycle, repeat.

Tried enabling xbox controller configuration, but nothing has changed.

Was working fine about a month ago, not sure when it got broken.

Otherwise very happy to see an update to SteamOS. Thank you, guys!

Is this a regression? We haven't changed those packages in quite a while. If you can test the newer packages rather than the older ones, we could look at updating them. (jessie-backports has intel-vaapi-driver 1.7.3-1~bpo8+1)

VAAPI hardware decoding reported working fine with intel-vaapi-driver=1.7.3-1~bpo8+1 from jessie-backports.

My exact packages updates (all from jessie-backports) were:

i965-va-driver=1.7.3-1~bpo8+1
i965-va-driver:i386=1.7.3-1~bpo8+1
libva1=1.7.3-2+bsos1
libva1:i386=1.7.3-2+bsos1
libva-x11-1=1.7.3-2+bsos1
libva-x11-1:i386-1=1.7.3-2+bsos1
libva-glx1=1.7.3-2+bsos1
libva-glx1:i386=1.7.3-2+bsos1


Please consider updating.

Yes, a regression, IIRC those packages were on 1.3.2 and have now been changed to 1.4.2.

Hardware decoding was working fine for those packages on the prior stable release (1.3.x), although the two latest beta releases (1.4.x) only supported software decoding on the CPUs that used it. The streaming logs reported a failure to initialize vaapi on the betas, whereas the latest stable reports nothing wrong, but only outputs a green screen.

As reported here (and I confirm that), versions 1.4.x of i965-va-driver:i386 libva1:i386 seem to be broken for Steam hardware decoding.

I'll test 1.7.3-1~bpo8+1 from jessie-backports later tonight and report back.
Thank you for the attention, loving my SteamOS so far.

make sure there are no errors. You may have to run some of these commands again because of version mismatches between i386 and amd64 packages, but they will be resolved once all of the packages are unpacked (unpack libva1 for i386, then amd64, then i386 again).

reboot

hope this helps. It got me running with my Intel Celeron 2955U from my repurposed ASUS Chromebox.

You, sir, are a gentleman and a scholar.

After hours of trying, this was the only solution that let me hardware decode without introducing issues with Kodi.

Reported STILL working fine on SteamOS 2.117 as of May-2017 on a N3150 CPU (Zotac ci323). Hardware deconding seemed right in the logs, but I only got a green screen with both brewmaster repos drivers.
