Hi, this is not really a bug, in that on some newer machines bbswitch doesn't work, so changing PMMethod from auto to none lets the kernel handle it (which works on those machines). Note that you'll probably want to also add: AlwaysUnloadKernelDriver=true As that will unload the kmods when optirun exists, allowing the kernel to turn off the card. Without it, the card will be left on and consume power even when unused. Unfortunately there's just no way at the moment to pick the correct setting. The default is what works on most machines. Also note that setting the Driver is not really necessary, it's smart enough to figure out if nouveau or the proprietary stack is running. It's the PMMethod that was needed in your case. -- Kind regards, Luca Boccassi
