[Solved] Choppy videos with Intel driver

My new laptop a Dell XPS 9310 is running a dual boot with win10 and a fresh new Arch. Everything it's ok but the videos. Audio is perfect but image stops for a instant every few seconds like something was wrong with decode. I have tried with several video files and youtube videos in chromium and firefox with no different result. I have installed gnome 3.40 and intel-media-driver for harware accel.

I appreciate your help

Re: [Solved] Choppy videos with Intel driver

That xorg log misses lots of lines .

I have installed gnome 3.40

If a problem occurs, view the log stored in either /var/log/ or, for the rootless X default since v1.16, in ~/.local/share/xorg/. GDM users should check the systemd journal.

If you are using GDM please run journalctl -b as root and post the output.
It will likely be large, consider using  a pastebin client

Did you use the guided installer ? If yes, I can't help you.

Re: [Solved] Choppy videos with Intel driver

My journal -b output http://ix.io/2UQY and  Xorg.0.log  http://ix.io/2UR1

I'm completely lost. I have installed an ubuntu in another partition to try and the videos run fine with the same i915 driver configuration but in my arch something goes wrong :-(

Thank you for the answer

Re: [Solved] Choppy videos with Intel driver

The xorg log looks ok but you're not using gdm it seems.

What are you using to start X ?

gnome 3.40 is not yet available from archlinux normal repos, where did you get it from ?

Re: [Solved] Choppy videos with Intel driver

I'm using official repos.

Yesterday unexpectedly I fix the issue. I upgraded systemd package to 248 and rebuilt kernel image. :-o
