[FIXED] XPS 13 2016 Intel Graphics GPU
I've used a XPS 13 9350 for the past 2 months, and did without fancy graphics so far. But I really need to have the GPU working properly to get usable perfs on webgl applications such as labster.
Right now, the experience is very slow, my 4 cpu processors being used at 100%. Since I have an Intel Corporation Skylake integrated Graphics, I'm running intel_gpu_top to monitor the gpu usage, and all I can see is the Graphics Arbiter (GAM) going sometimes up to 4%...

Can someone help me fix this issue, so I can use this computer to its full potential ? Or at least get a not-too-slow experience with webgl applications on chrome...
Thanks in advance!
EDIT 1: I've installed the firmware components GuC and DMC from https://01.org/linuxgraphics/intel-linu … -firmwares. But after rebooting, I'm not sure how to verify if these components are working and monitor their performances. gpu still looks unused

Re: [FIXED] XPS 13 2016 Intel Graphics GPU
Sorry about that, fixed. The text didn't really matter, it was just an illustration to the sentence above it (100% cpu usage, 0% gpu usage).
To go back to my problem, here are more information from the result of PowerTop

It confuses it that GPU ops/seconds is reported by powertop when intel_gpu_top doesn't return anything
Also, it seems that my recent installation of GuC and DMC firmwares wasn't successful, will debug:

Re: [FIXED] XPS 13 2016 Intel Graphics GPU
Well, it looks like I could fix my issue by removing /etc/X11/xorg.conf.d/20-intel.conf and removing the package xf86-video-intel (hence restarting Xorg with modesetting and glamor, which are the default)
