Black screen on Tensorflow

post by ife497 on Mar 2, 2023

After having problems on connecting to GPUs in Julia, I decided to give a trial in updating Ubuntu and Lambda stack, following the instructions given here:

Unfortunately, after the command

sudo do-release-upgrade,

The computer restarted and a black screen with a small white “-” on the left top of the screen appears, and apparently it does not respond to any command.

I would like to ask advices on how to solve this problem.

This likely means that the GUI terminal session is in use.

1. Hit one of the combinations ‘Control-Alt-F2’ to ‘Control-Alt-F5’
   • This will go to a command line session
2. Login
3. Clean up and reconfirm install
   • One reason is some commands create a xorg.conf

   $ sudo rm /etc/X11/xorg.conf

• Check if apt is up to date or if there is a issue.

   $ sudo apt update
   
   $ sudo apt upgrade
   
   If you get errors like ‘–fix-missing’ and/or ‘–configure’

$ sudo apt install --fix-missing

or

$ sudo dpkg --configure

And you may need to clean up:

/etc/apt/sources.list
/etc/apt/sources.list.d/*
