Recently just switched to ubuntu from windows 10, and so far i love it! But i got a problem, when ever i do pretty much anything my gpu usage jumps close to 100% and everything becomes very laggy and sluggish, even when i just browse the web in firefox, now i didn't had this problem in windows, and i have no idea what might cause this, the problem seems to be worst when im running on battery, and not when im plugged in, though i need to do more testing about that. Is there someone who has any idea what might cause the big jump at gpu usage, any help will be much appreciated.

  • Laggy how? Slow moving windows around or screen tearing when scrolling in browser? Is the 367 the recommended/tested driver you get from the software updater /settings/ additional drivers tab? – ubfan1 Mar 2 '17 at 22:28
  • Slow moveing windows, extremely slow when tab swi thing and video freezing constantly. Yes, i am running the recommended proprietary nvidia driver. – Victorwp Mar 3 '17 at 4:45
  • Check your BIOS/UEFI Settings for video control. Start with the dedicated, then if OK, try the optimus (switches back and forth with integrated, but that's not for performance). – ubfan1 Mar 3 '17 at 5:19
  • Can't see to find a tab for video control in my UEFI? I have found that the problem is worst when im running on battery, when im plugged in, my gpu never goes above 50% while browsing ( which still seems high?) and there is no lag to speak off, while doing everyday task. – Victorwp Mar 3 '17 at 6:46
  • use top or htop to see what process is using your CPU the most. Sometimes, when I boot, I see python3 is over using my CPU. – Mostafa Ahangarha Mar 3 '17 at 9:23
