It's working here with an Intel Core i5-7200U CPU (Intel HD 620);
"intel-gpu-top" confirms it is. Both VP9 and h264 are accelerated. CPU
usage is around 20 to 35% while playing a 1080p video on Youtube (VP9),
and a bit higher on Twitch (h264). Though it's way better than with
software decoding.

I'm sorry for spamming this bug report, I should've make all my tests
before posting anything.
I made a clean install today but, this time, without installing the
proprietary drivers during setup. I installed the Nvidia driver after
the first batch of updates, via the Additional Drivers applicatio
I managed to resolve this issue _on my laptop_ by manually editing
/usr/bin/prime-select at lines 161, 162.

After trying with kernel 5.6, it still don't work as intended despite Powertop
reports it now as Good. Power consumption is still high (around 12W at idle),
and "sudo cat /sys/bus/pci/devices/:01:00.0/power/runtime_statu
The workaround didn't work after shutting down my laptop.
But, after digging a bit, I found a news on Phoronix (
https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.5-dGPU-Sound-Bind-Power
) that gave me the idea to try with kernel 5.6. This one, to be more specific:

Same issue here with an Intel Core i5-7200U and an NVIDIA Geforce GTX
950M. Had to use the same workaround with Powertop and power consumption
went from 12W to 6W after. It kept working after restarting, though.

Same "libva error" issue here, with an Intel Core i5-7200U CPU (Intel HD
620). I attached the output of running "chromium --enable-
logging=stderr", the chromium's journalctl entries (from installation to
first and second launch) and vainfo.

I tried something this morning, since I was convinced that this problem
revolves around Nouveau power management.
I made a backup of prime-select,
# cp /usr/bin/prime-select /usr/bin/prime-select.orig
and replaced the parameter that disables Nouveau power management (as per

Seems like you're right, François. I installed Powertop on both Ubuntu 18.04
(~12.5W at idle) and Fedora 27 (~5W) on the same laptop to measure the power
comsumption. The method is not what I'd call scientific, but the difference is
big enough to tell there's indeed something wrong.

I didn't know about the SLI breakage, my bad.
Just did a clean install and I can confirm that it's working as it
should:
$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x65 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 3
associated providers: 1 name:modesetting

So, if I understand what's happening here. When switching to Intel, both
Nouveau and the proprietary driver are blacklisted and the power
management is disabled because of "nouveau.run-pm=0" kernel parameter.
The discrete GPU is therefore always ON, but cannot be used at all.
Why not just blacklis
I don't experience this issue anymore on Ubuntu 14.04 with Vivid kernel
and X stack from proposed updates repository. By the way, I never
encountered this bug on Vivid, in the first place.

Found a related bug report here:
https://bugs.freedesktop.org/show_bug.cgi?id=77074
Seems to be fixed, but I'll have to wait for the next LTS enablement stack
(14.04.3) to check.
The temporary fix is to switch to UXA, as the acceleration method.

Found a solution, thanks to this:

First, you have to add "drm.rnodes=1" to the kernel parameters:
https://wiki.ubuntu.com/Kernel/KernelBootParameters
Then, you need to make sure you (the user) are in the video group: sudo usermod
-a -G video
