The nouveau module is loaded, the card is visible by vgaswitcheroo, but I cannot switch to it (nor force to turn it on). > # lsmod | grep nouveau > nouveau 2293760 1 > ttm 122880 1 nouveau > i2c_algo_bit 16384 2 i915,nouveau > drm_kms_helper 225280 2 i915,nouveau > mxm_wmi 16384 1 nouveau > drm 577536 15 drm_kms_helper,i915,ttm,nouveau > video 53248 2 i915,nouveau > wmi 36864 4 intel_wmi_thunderbolt,wmi_bmof,mxm_wmi,nouveau > # cat /sys/kernel/debug/vgaswitcheroo/switch > 0:IGD:+:Pwr:0000:00:02.0 > 1:DIS: :DynPwr:0000:01:00.0 > 2:DIS-Audio: :DynOff:0000:01:00.1 On: > echo ON > /sys/kernel/debug/vgaswitcheroo/switch there is no effect.
