dmesg log
Gentoo linux ver. 4.9.16 - using vgaswitcheroo, modesetting and nouveau.
My laptop is a Tuxedo XC1706 (aka Schenker XMG P706 aka Clevo P671RG)
(i7-6700HQ/GTX 970M), external outputs (HDMI and 2 x DP) are wired to the
NVIDIA card. The intel HD only has the laptop screen attached.
Issue 1 (minor):
----------------
Without pcie_port_pm=3Doff and on battery I see DynOff, but ~26W with power=
top
(i.e. nvidia card is not turned off).
With pcie_port_pm=3Doff and on battery I see DynOff and 16-18W with powertop
(i.e. nvidia card is turned off).
Issue 2:
--------
With pcie_port_pm=3Doff and on AC I always see DynPwr even though the nvidi=
a card
is unused (see below) - shouldn't this change to DynOff when unused? Is the=
re a
workaround way to force this to DynOff?
