+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
+</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.
