This tutorial will show you how to install Cairo Dock 3.0.2 in Ubuntu 12.04.There were many updates and bug fixes happened in this version.

After installation , you can either choose Cairo deck with OpenGL or without OpenGL.

New things in Cairo Deck 3.0.2 :

Core:

Main GUI: Fixed a crash when hovering group buttons too quickly
Main GUI: The dialog and preview didn’t appear when hovering the button
Accelerators: On recent distro, ‘Control’ key is now called ‘Primary’
Icon Mgr: Added a mutex because of occasional crashes with gtk_icon_theme_lookup_icon
Icon Mgr: Don’t call a ‘change-icon’ callback when clicking or scrolling on an icon, and trigger an unneeded animation on the icon
Dock Mgr: Avoid emitting an ‘enter’ event when not needed
Class Mgr: Fixed 2 typos (special case for kdesu and not kdes)
Class Mgr: Remove launching options (%U) in quick-list Exec command
Dialogues: Prevent closing the dialog unexpectedly when clicking on it, if the click is actually inside the interactive widget
Background: When set to ‘always visible’, applets’ background couldn’t be turned off
Added a workaround for the Unity-panel which has a wrong window type
Po: Updated translations: thanks to all contributors

Plug-ins:

AlsaMixer: Fix: double-clicking did nothing if we didn’t open the menu of the applet
DND2Share: Pastebin: Their public API is no longer available -> ported to the new API
GMenu: Fixed a bug that made sub-menus be too small, and therefore have to be scrolled + code cleaning
Logout: When the menu is reversed (top dock), select the last item so that it’s the same as the normal menu (ie, the ‘shutdown’ item)
MusicPlayer: Prevented a warning message: when changing song, we don’t receive this value: Position => no need to display a warning message each time
MusicPlayer: Allow recently played files in the menu (Recent-Files)
MusicPlayer: Fixed a bug that prevented the player from being launched the 2nd time in some cases
MusicPlayer: Added raise and quit methods in the menu when the player is in the systray (without that it’s hard to display the window
MusicPlayer: Used toggle buttons for Shuffle and Repeat properties
Recent-Events: If the file doesn’t exist, don’t display it in the ‘Recent Files’ menu
Recent-Events: Prevent doubles in the menu list
Po: Updated translations: thanks to all contributors (added Croatian)
Shortcuts: Fixed a small bug with bookmarks (extra new lines were disrupting Thunar)
Status-Notifier: Added the marshaller for the XAyatanaNewLabel signal
Systray (old): Force the icons size to 24px, to avoid buggy programs to display their icon with a wrong size
Third-party applets: Reposition their right-click menu, so that it’s the same as a normal menu (on top of the icon and no scroll needed)
Fix 3.0.1 regression: GMenu, Switcher, Quick-Browser and Terminal: CAIRO_DOCK_FORCE_ICON_IN_MENUS was not defined in plug-ins (these applets didn’t contain any icons except if ‘menus-have-icons’ [gd]conf key was enabled)
