Same issue here on XPS 15-9530. I fixed it by switching to the nvidia 364 drivers from the graphics driver ppa:
sudo apt-get purge nvidia-361 sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt-get update sudo apt-get install nvidia-364 A full system restart (twice for some reason, power down on the second try) was required to get everything working. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1559304 Title: nvidia 361 drivers cause unresponsive machine To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1559304/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
