-__20 Jul 2020__
-Updated VirtualBox to 6.1.12 and Ubuntu 18 would not login after MATE authentication screen (just got black screen).  Went into /opt/VBoxGuestAdditions-6.1.8 and uninstalled the Guest Additions.  Rebooted, logged in correctly.  Then installed latest version of GuestAdditions.  Rebooted again, logged in and all worked correctly.

-Logging into Desktop GUI only gives a blank screen:
-  * Tried updating VirtualBox Guest Additions to v5.2-5.2.24 but no change
-  * Tried updating packages using commands below
-Use these commands to update packages, as it allows interactive use to answer questions:
-<code>
-sudo apt update
-sudo apt upgrade
-sudo apt --with-new-pkgs upgrade
-</code>
-Very slow using Ubuntu GUI now:
-  * Enable 3D acceleration in VirtualBox settings
-  * Allocate 128MB video RAM
-  * Restart and test
-  * Also see these links:
-    * [[https://thomas.vanhoutte.be/miniblog/guide-speed-up-ubuntu-virtualbox/|Speeding up Ubuntu]]
-    * [[https://www.linuxbabe.com/virtualbox/speed-up-ubuntu-virtualbox]]
-Check that 3D acceleration is supported:
-  sudo apt install nux-tools
-  /usr/lib/nux/unity_support_test -p
-Installing mysql:
-<code>
-sudo apt install mysql-client-core-5.7
-sudo apt install mysql-server
-sudo /usr/bin/mysql_secure_installation
-</code>
-Then login like this:
-  sudo mysql -u root -p
-Login with a non-root user like this:
-  mysql -u username -p
-See notes at [[https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-ubuntu-18-04]] for setting up a new user
-Other SQL commands/testing:
-  CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
-  GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' IDENTIFIED BY 'password';
-  CREATE DATABASE dbname;
-  SET PASSWORD FOR 'username'@'localhost' = PASSWORD('password');
-To fix this locale error upon login:
-<code>
--bash: warning: setlocale: LC_ALL: cannot change locale (en_US)
-</code>
-run the following:
-  sudo locale-gen en_US
-  locale -a
-and confirm you see en_US now.  See [[https://ubuntuforums.org/showthread.php?t=1675347&page=2]] for more info.
