Same thing happened to me. When I tried to reboot with previous kernel the mouse and keyboard would disappear. Removing Nvidia driver got me back to the desktop. In my case original nvidia drivers was the cause and switching back to open source nouveau helped. First, I removed all stuff from nvidia:
1. sudo apt-get remove --purge 'nvidia-*' 2. sudo apt-get install ubuntu-desktop 3. sudo rm /etc/X11/xorg.conf 4. echo 'nouveau' | sudo tee -a /etc/modules (source: How can I uninstall a nvidia driver completely ?) After that I could login, but unity didn't load, there was no launcher etc. It turn out I had to re-enable Unity plugin: 5. sudo apt-get install compizconfig-settings-manager 6. DISPLAY=:0 ccsm 7. Find the Unity plugin and enable it. (source: Unity doesn't load, no Launcher, no Dash appears) Found this solution in one of the Ubuntu forums. Steps 6 and 7 didn't apply to me so I just rebooted after and I could log in. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1742302 Title: Kernel 4.13.0-25 broke nvidia driver Status in linux package in Ubuntu: Confirmed Bug description: After updating to linux-image-4.13.0-25-generic the binary nvidia driver 387.22 cannot be built.
