I had a problem today, when I install the lastest updates, including the headers for linux kernel, tha graphical environment did'nt work, so I've tried upgrade the system, but the terminal even doesn't work, after I restart the system under the kernel 3.19.016 and the graphical environments back to work. The question if anybody knows the solution is how can I repair the kernel problem?, or uninstall the update of kernel 3.19.018? By the way, I'm using ubuntu gnome 15.04............
Thanks.
