I just use dd -ip /dev/sda -op /dev/sdb to clone my old disk to new disk, and boot from my new disk. All the things remain the same except that applications in Launcher changed back to default. Why? And I cannot unlock from Launcher and lock to Launcher, it sucks, any help?

I found that answer. But to be more helpfule, i will show you how to debug it.

  1. Since it's something related to Launcher, And i don't know how does Launcher work, so i just need to find something related to Launcher. Which is Appearance in Dash.(I found this by Google).
  2. Under Behavior tab, I can't change everything, i can click the checkbox, but nothing happen.
  3. So, now i think there should be some output information in terminal. So i need to know how to open Appearance in terminal
  4. Found Appearance in /usr/share/applications, the command is unity-control-center appearance
  5. Type unity-control-center appearance in Terminal. And do the same thing as step 2. Terminal show output like this:

    dconf-WARNING **: failed to commit changes toconf:GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._g_2dfile_2derror_2dquark.Code17: Cannot open dconf database: invalid gvdb header

  6. Of course i don't know what the hell it is. But i now get some new key word to search on the Google! Yeah! I searched Cannot open dconf database: invalid gvdb header
  7. And I found solution, just remove ~/.config/dconf/ (Of course backup first)
