I have just finished installing Ubuntu 12.04.2 LTS 32 bits on my Toshiba Satellite L355D-S7809 laptop. I have performed apt-get update and upgrade and rebooted. The mouse movement on the login screen is very slow. After logging in it works fine. How can I troubleshoot it? The mouse is an USB mouse from an extremely generic brand, it works fine on Windows and on Ubuntu other than on login screen.
Edit the mouse movement settings for the
root
user, by running the setting manager as root:The settings on this screen will be saved for the root user only, and be effective before session login after boot, on the user selection screen.
