I am using gnome-flashback (gnome-panel) with Compiz. I first recognised that Compiz is giving very high CPU loads according to top. At the same time, intel_gpu_top shows GPU usage at an unchanged 0%. The same happens when running glmark2: CPU usage climbs to >400% while GPU stays at 0%. Interestingly, OpenGL seems to be enabled - please see the glxinfo outputs below. Switching to todays latest oibaf drivers did not make any difference. Any pointers are much appreciated. r. --- H/W: CPU: Core i7-7700k @ 5GHz GPU: Using Intel IGP (HD630) RAM: 16GB DDR4 SSD: Intel Optane S/W: $ cat /proc/version Linux version 4.15.0-11-generic (buildd@lgw01-amd64-016) (gcc version 7.3.0 (Ubuntu 7.3.0-5ubuntu1)) #12-Ubuntu SMP Fri Feb 23 18:39:58 UTC 2018 $ lspci -nnk | grep -iA2 vga 00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 630 [8086:5912] (rev 04) Subsystem: Gigabyte Technology Co., Ltd HD Graphics 630 [1458:d000] Kernel driver in use: i915 $ modinfo i915 srcversion: 4963AD5BD78D754BBD09EAF name: i915 vermagic: 4.15.0-11-generic SMP mod_unload signat: PKCS#7 $ dpkg -l | grep xserver-xorg-video-intel ii xserver-xorg-video-intel 2:2.99.917+git20171229-1 amd64 $ dpkg -l | grep xorg ii xorg 1:7.7+19ubuntu5 amd64 $dpkg -l | grep mesa ii libegl1-mesa:amd64 18.0.0~rc4-1ubuntu3 $ glxinfo | grep -i opengl OpenGL vendor string: VMware, Inc.
