--- Comment #12 from Marcin Zajaczkowski <[email protected]> --- I managed to build and install 3.13-rc1 with CONFIG_PM_RUNTIME on my Fedora, but I have two issues. 1. I can't determine if NVidia card is disabled when become not used (basing on a system temperature it's not). vga_switchero always returns DynPwr - can vgaswitcheroo be more verbose? $ sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynPwr:0000:01:00.0 I need to build and install patched for 3.13 bbswitch version which shows: $ cat /proc/acpi/bbswitch 0000:01:00.0 ON and I cannot disable it using bbswitch. bbswitch: device 0000:01:00.0 is in use by driver 'nouveau', refusing OFF I also cannot unload nouveau driver. There is nothing more in the kernel log. 2. I tried to boot with bbswitch (then vgaswitcheroo become disabled) and a discrete is turn off. Unfortunately and cannot tell Prime to use it for offloading because xrandr --listproviders returns only Intel card. Even when I manually enable discrete card and later load nouveau driver xrandr returns the second card with modesetting instead of nouveau (can I do something in that case?) -- You are receiving this mail because: You are the assignee for the bug.
