I need to increase the hold delay to move an icon in the Unity launcher in Ubuntu 13.10. How do I do that ?

I need this because of latency of remote desktop access: a short click acts as a long one in the server/distant machine, and so I can't launch/select an application from the dock.

  • Have you try unity-tweak-tools ? I'm not sure if this option is in it, but it's worse the try ! – Laurent Jan 16 '14 at 12:40

I believe that using gsettings to change grab-wait in com.canonical.Unity.Decorations is what you want.

This value is described as:

Milliseconds to wait before considering a mouse pressure a grab

On the command line

You can read your current setting:

gsettings get com.canonical.Unity.Decorations grab-wait

You can set it:

gsettings set com.canonical.Unity.Decorations grab-wait 1000

In a GUI

Alternatively, you can install the gui dconf-editor and use that.

You will need to rebuild the unity source after finding where and how the duration from 'open' to 'grab' is set. This may prove simple or complex.

As a starter will point you to one possible area to check /launcher/Launcher.cpp, line #76 (or thereabouts, looking in current 14.04 unity source, times are in ms):

const int START_DRAGICON_DURATION = 250;

As far as rebuilding, installing unity source - strongly advise doing as Debian packages the same way as Ubuntu does. Possibly another question as how to do that properly.
