 +  * Allow Virtualbox guest additions:

 +__26 Jan 2019__
 +
 +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:
 +  * Basically enable 3D acceleration in VirtualBox settings
 +  * Allocate 128MB video RAM
 +  * 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.
