Thanks Mykola,
I've tried all this things. IMO problem is, that nvidia card cannot recognize display. I've read that this is problem on some laptops. Maybe it's bug in driver.
No, you are not connected to any display - this is normal. It's only a virtual X, the card renders the frames, but the output is sent to another X (if I understand things correct).
Be it as it is, I do get exactly the same messages in Xorg.log, and also my nvidia-settings tells me screen is at 640x480. My laptops' screen is 2560x1440. So that is not the issue...
One stupid question: Is your battery inserted? When I got my laptop new I continued my habit to remove the battery when on AC (improves lifetime a lot...), but then my Lenovo would only run at lowest CPU speed (800MHz)....
Yes, Peter is right, that's not a sign of issue. TBH, I've run out of ideas. The only I could suggest to install parallel openSUSE Leap 42.2 and install drivers from official nvidia repository without Bumblebee at all and check performance there. If it is low, then it's definitely nvidia problem. If it's ok, then Bumblebee (or something other) has an issue. -- Kind regards, Mykola Krachkovsky -- Найкращі побажання, Микола Крачковський
