But it has 2 major issues: 1. Huge Xorg CPU usage with intel driver...more than 110% on glxgears without vsync (with modesetting driver Xorg has zero CPU usage and very good Opengl performance) 2. on DRI3 glxgears it skip most frames and display one frame every 60-70 frames but reported FPS is doubled than on DRI2 to reproduce a problem install fresh server image of 18.04 and then install minimal xinit+xserver-xorg-video-intel. Put 20-intel.conf to enable intel driver. Run X by startx and then run glxgears. 20-intel.conf: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "true" # Option "DRI" "3" EndSection P.S. Before 18.04 I tried 16.04 with HWE kernel...on stock Xserver and Intel driver it just crash. On latest HWE xserver and HWE Intel driver it works the same as 18.04 because it has the same versions. But with old 1.18 xserver and HWE intel driver it works in DRI2 mode...Xorg CPU usage just 10% instead of 110% on xserver 1.19...The only problem - poor OPENGL performance (glxgears 5400 fps vs 8000 fps on 1.19 xserver)" Best regards, -- Cristian Aravena Romero (caravena) Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1797604/comments/2 ------------------------------------------------------------------------ On 2018-10-12T19:39:18+00:00 Chris Wilson wrote: commit e7bfc9065345085f767235eea8b148c356e5bd2b Author: Liwei Song <liwei.s...@windriver.com> Date: Thu Mar 15 23:14:18 2018 -0400 Add Coffeelake PCI IDs for U Skus Add the Coffeelake PCI IDs based on the following kernel patch: commit d29fe702c9cb682df99146d24d06e5455f043101 Author: Anusha Srivatsa <anusha.sriva...@intel.com> Date: Thu Jun 8 16:41:07 2017 -0700 drm/i915/cfl: Add Coffee Lake PCI IDs for U Sku.

If you want I can try any newest kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline that already have this patch.

The problem is in the Xorg-> Driver-> Intel. Because your computer is relatively very modern. If you are very impatient, try the live-cd of the next version of Ubuntu (18.10): http://releases.ubuntu.com/18.10/ To see if in this version your problem is solved.
