I think I somehow broke my visual GUI of my ubuntu-16.04.3 LTS. It does not accept neither keyboard nor mouse interaction anymore (and doesn't show the mouse pointer at all).

I'm running the OS inside a virtualbox, but that doesn't seem to bee the problem, since I was able to start the system with advanced options without a gui. (start 'Ubuntu, with Linux 4.10.0-38-generic (upstart) )

first error message after login:

[ 11.155750] systemd-logind[1463]: Failed to enable subscription: Launch helper exited with unknown return code 1

[ 11.155779] system-logind[1463]: Failed to fully start up daemon: Input/output error

Now the last things I tried to do before this happened was to install virtualbox-guest-x11, and because that didn't work initially, also xserver-xorg-core as recommended here: Installing Guest Additions causing problems

After rebooting, the problems started.

Anyone knows what I did wrong? I could just install a new VM since I have all important files saved, but I don't want to reinstall all my programms...

Nevermind, I solved it. I just reinstall the xorg-stuff, as shown here: http://www.ubuntugeek.com/ubuntu-tiphow-to-removeinstall-and-reconfigure-xorg-without-reinstalling-ubuntu.html

sudo apt-get remove --purge xserver-xorg
sudo apt-get install xserver-xorg
sudo dpkg-reconfigure xserver-xorg

Everything works fine again.
