Black screen after entering the password on Ubuntu Gnome 16.04

  • 772

I'm having this issue where I enter my password and all I get is a black screen with the mouse cursor moving around, it's the same closed issue from here.

Purging package configuration doesn't do anything, and lately pressing CTR + ALT + F1 won't bring up the console like it should, so I have to shutdown the system and start again!

My kernel version is: 4.4.0.53 and I have an Intel graphics card.

Could it be related to the /dev/sda1: recovering journal? I've been getting that more often lately (we have electrical issues).

At times the boot logo would delay for several minutes as well, is that related?

Found this link on launch pad that is similar to my issue: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1559576

16.04

  1. There seems to be an error in the last kernel update. Try to use an older kernel version under extended boot options.

    4.4.0.42 --> stable ! with Intel GPU.

    As shown in this launchpad bug report there is a bug affecting Lenovo laptops that has Ubuntu Gnome installed, and it's not resolved yet. The only workaround is to install LightDM and set it as the default login manager.

  3. I dont know surely, but had this problem once too when I was frickling with nvidia-driver in the past with Ubuntu 13.10. You might try following three steps in terminal :

    1.)

    sudo /etc/init.d/gdm stop

    2.)

    sudo dpkg-reconfigure xserver-xorg

    3.)

    sudo /etc/init.d/gdm start

    Instead of step 2.) you might try :

    sudo apt-get install --reinstall xserver-xorg

    Hope this hits as solution to you. In case gdm was lost before you might try too :

    sudo apt-get install --reinstall gdm

    In the end you should clean up with :

    sudo apt-get autoremove

    In case gdm was not installed with gnome together, then after:

    sudo apt-get install gdm

    there should following :

    sudo service lightdm stop

    and

    sudo service gdm start

    Then reboot the machine.
