Hi, Unfortunately I'm unable to reproduce on my jessie optimus laptop. You mentioned that you installed "nvidia-kernel-dkms". Why only the DKMS package and not everything else? Please install nvidia-driver to make sure everything is correctly pulled down. If all the packages are from the 352.79 backported version and the problem still persists, please attach the result of: reportbug --template nvidia-driver Kind regards, Luca Boccassi
