I want to disable rc6 power savings because it is a tower machine with a kilowatt supply and lots of fan so I don't give a rip about power consumption, I do not want my display interrupted while I'm watching a movie or video and when monitoring things I want to be able to walk by the monitor and see what is going on without having to go up and wiggle the mouse and wait for it to wake up and my monitor to sync. I have an i7-9700k on an Asus Z390A Prime motherboard. I have enable RC6 disabled in the BIOS so BIOS isn't enabling it, in /etc/modprobe.d/i915.conf I have: options i915 enable_guc=3 enable_dc=0 enable_rc6=0 In /etc/default/grub I have: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash xdg.force_integrated=1 modprobe.blacklist=nouveau i915.i915_enable_rc6=0" I have done update-grub2 and update-initramfs -u -k all and rebooted, but still: cat /sys/class/drm/card0/power/rc6_enable 1 The kernel totally ignores my instructions and enables the damned thing anyway.
