Public bug reported:
I have installed 18.04.1 server on Intel NUC NUC8i5BEH with minimal xinit and
xserver-xorg-video-intel. 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)
