As another workaround it is possible to disable the hotplug events in xorg conf.
here the steps:
switch to tty (crtl + alt + f1) and log in.
sudo service lightdm stop
sudo Xorg -configure   # this creates an xorg.conf and displays where it is 
stored
sudo cp /path/to/xorg.conf.new /etc/X11/xorg.conf
sudo vim /etc/X11/xorg.conf

then add to the "Device" section: 
 Option "UseHotplugEvents" "false" 

save and quit and restart lightdm:
sudo service lightdm start
