Cinnamon software rendering on Intel HD Graphics 520

Post by reptile »

Hi!

Problem statement: Can't get Cinnamon and X to use graphics accellerator. Cinnamon complains about working in Software Rendeiring mode. Indeed, CPUs are utilized enormously (40-300%) when simply dragging windows around... Battery lasts just a fraction of the time that is expected.

OS: LMDE2 64bit (latest main and non-free packages. backports enabled for 4.8 kernel)
Laptop make and model: HP EliteBook 820 G3 Notebook with an Intel HD Graphics 520 chipset.

uname -a
Linux ... 4.8.0-0.bpo.2-amd64 #1 SMP Debian 4.8.11-1~bpo8+1 (2016-12-14) x86_64 GNU/Linux

GRUB addition
i915.preliminary_hw_support=1

lspci
00:02.0 VGA compatible controller: Intel Corporation Device 1916 (rev 07)

Graphics: Card: Intel Device 1916
Display Server: X.Org 1.16.4 drivers: intel (unloaded: fbdev,vesa) Resolution: 1368x768@60.00hz
GLX Renderer: Gallium 0.4 on llvmpipe (LLVM 3.5, 256 bits) GLX Version: 3.0 Mesa 10.3.2

sudo lsmod | grep i915

drm 360448 4 i915,drm_kms_helper
video 40960 1 i915

Tried 'glxdemo' and got such an output:
libGL error: pci id for fd 4: 8086:1916, driver (null)
[intel_init_bufmgr:1068] Error initializing buffer manager.
libGL error: failed to create dri screen
libGL error: failed to load driver: i965

Graphics firmware
skl_dmc_ver1_26.bin was downloaded from here: https://01.org/linuxgraphics/intel-linu ... -firmwares

$ sudo dmesg | grep 915

Could someone more knowledgeable please hint, what am I doing wrong or what else could be tried to unlock the skylake chipset potential fully?

Thank you in advance!

I was thinking that maybe you had to install this non-free binary drivers for your graphic card, but it seems that you already did it. :?
