<pre>I desire to turn the power management feature of the i915 driver off so that I
can watch videos or movies uninterrupted. I have a home brew PC consisting of
an Asus Z390A Prime motherboard, an I7-9700K CPU with integrated graphics, and
am using the on board graphics. I am presently running a self compiled kernel
from
kernel.org, version 5.2.13, but I have also experienced the same problem with
the 5.00 kernel shipped with Ubuntu 19.04.
Even with all screen savers and screen blankers not only turned off but
removed entirely from the system, the screen will still go black and lose sync
after about 10-15 minutes even when video is playing.
I have RC6 power management disabled in the BIOS, I attempted to disable
it
in the kernel by adding options i915 enable_rc6=0 to /etc/modprobe.d/i915.conf
and regenerating initramfs with update-initramfs -u -k all and when that failed
to have effect I tried adding i915.i915_enable_rc6=0 to the
GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and update-grub, still not
effective.
When I boot I see:
[ 1.259045] i915: unknown parameter 'enable_rc6' ignored
Before compiling an upstream kernel and determining the problem was not
specific to Ubuntu, I filed a bug report on launcpad.net: #1843511</pre>
