Hi Julien, Could you please run: reportbug -N 822330 nvidia-driver This will attach (a lot of) additional information that will be useful to debug. Having said that, I regularly run newer versions of the drivers package from our SVN with bumblebee and haven't seen this. Unfortunately Bumblebee's error messages are very often a bit misleading. As a test, on my Jessie laptop I removed all nvidia packages, installed from stable, all good. Then upgrade to jessie-backports, still all good. First of all, make sure you don't have xserver-xorg-legacy installed, as there's a known incompatibility. Then, do you have update-glx installed from jessie-backports? If so, run again sudo update-glx --config glx to make sure all symlinks are in the right place, including the modprobe conf files. Kind regards, Luca Boccassi
