Trying to boot I get the following kernel panic just before I would enter my password (Ubuntu 14.04 with 3.13.0-140-generic):
I am able to boot with the older kernel 3.13.0-139-generic.
I reinstalled the linux-headers-3.13.0-140-generic and linux-image-3.13.0-140-generic using synaptic, now I don't even see the output anymore, only a black screen.
Any help and advice is very welcome! I don't know too much about Linux, although I am only using it for selveral years now...
SOLVED: Uninstalling Teamviewer solved the problem! Only tried it because it was mentioned in the posted Screenshot.
