I tried that, and confirmed that I changed the setting by watching this value toggle from 1 to 0 and back on multiple reboots: cat /sys/class/drm/card0/power/rc6_enable
Since I'm on EFI, I manually edited the /boot/efi/EFI/qubes/xen.cfg file and didn't run grub2-mkconfig and it still turned rc6 off and on with that parameter you mentioned. It didn't help my suspend issues. It suspends, and the power button blinks slowly, then no matter what I do (clicking power, typing, clicking the mouse, plugging and unplugging cables) nothing changes that steady blink of the power button until I hold it for ~10seconds. There's another value in the KERNEL parameter, i915.aplha_support=1. I changed it to 0 as well (which disables it). This also had no effect. I need to learn how to troubleshoot this better. I'm at a loss right now. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
