Leo:Ubuntu config

This list gets updated as I remember or install new essentials for my Ubuntu environment.

Private config

I have my private config in a SVN repository, so I can update my various workspaces. Some examples for stuff in my configuration:

• startup scripts: .bashrc and various dot-files
• aliases
• ~/bin - various custom scripts
• ~/lib - custom libraries
• icons
• work environment configurations, for example, custom menus in Nautilus

One could keep the configuration in Dropbox or similar cloud storage, but I choose not to because of security reasons.

Config

Power button to shutdown, no prompts

1. sudo gedit /etc/acpi/events/powerbtn
2. Add # to comment the line: # action=/etc/acpi/powerbtn.sh
3. Add a new line: action=/sbin/poweroff
4. Save file
5. sudo acpid restart
