There are other questions with the same issue (here and here), but in my case, instead of a MacBook I have this (I am not doing any kind of promotion of this product)
Until today, everything was working. I did not add or remove any hardware. The computer is running an ubuntu 15.10 with Gnome 3.18. Yesterday, the kernel was updated to the version 4.2.0-36-generic. Everything was working out of the box.
I tried adding the nomodeset
parameter to grub, also unplugging any USB device (except the keyboard). The error is the same if I try the previous kernel version.
As I do not have an up to date backup, re-install is the last option I want to try.
