Hi there, This is re: recent nouveau runtime PM functionality. For the most part it works great, but the Nvidia card powers up briefly when it shouldn't, e.g. opening a video with VA-API in mplayer. Which is alright - I greatly appreciate the cooler temperatures. However, a VT switch, e.g. ctrl + alt + F2 and back, the Nvidia card never turns off again until all X sessions are closed. Is that just a limitation of X or fixable?
