I'm updating with a little bit more info my problem. After installing nvidia-313 from xorg-edgers ppa I got a new problem that my BIOS didn't everything recognize my discrete NVIDIA card. I don't think it's caused by the driver, but it's just a coincidence. So anyway I started researching it and I came accross one of the options in my BIOS in "Advanced" tab "Primary Display". It had two options "SG"(Switchable Graphics) and PEG(Peripheral Graphics). On SG I have Optimus enabled and on PEG I have only my discrete card enabled. On SG I was suffering the problem that my NVIDIA card isn't found each time, while on PEG it was found each time. So after setting Primary Display to PEG I installed again nvidia-313 package and tried PowerMizer. This time it worked. I tested with "Amnesia: The Dark Descend" and the game wasn't lagging anymore. After checking PowerMizer I confirmed that it was moving successfully between all 4 performance levels. There was something that I didn't like about it though. PowerMizer was preffering the loweest and highest performance levels. For example if I'm on the lowwest and started changing desktops, the desktop animations lag a little but PowerMizer statys in lowwest level. When doing the same when in highes level it doesn't go down.
So it looks like when Optimus is enabled PowerMizer isn't working correctly, but when it's disabled PowerMizer can use all performance levels. I hope this helps you to easier localize the problem. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/1096155 Title: PowerMizer's performance level goes max to lv.2 from 4 possible on NVIDIA GTX series.
