How can I disable a shortcut (Ctrl + LMB) in Ubuntu 11.10 without the compiz-manager? The compiz-manager destroys my desktop therefore I cannot use it. Is there a config file where I can disable this shortcut instead?


I now found out the solution. You have to change they keys from Alt to Super. The command is as follows:

gconftool-2 --set --type string /apps/metacity/general/mouse_button_modifier '<Super>'

It works for me.

I found the solution from the question can I disable the Alt + Windows + Right Click behaviour for editing panels in Gnome Classic.


It would appear that if the Move plugin itself is enabled it's going to want something valid for that key, if you disable the key it comes back.

So maybe try something not being used elsewhere that will 'stick'



You should be able to use ccsm in 11.10 without much issue, there are just a few things to stay away from, editing the Move plugin wouldn't be one of them

Changes to compiz plugins from gconf-editor sometimes require a log out/in to realize (or restart compix


I would answer your question but in a slightly different way than you, probably, expect. I think in Ubuntu 11.10 you should fight the CompizConfig once and then not be afraid to use it anymore...

It indeed destroys your desktop the first time you run it when you select some of its options (for example, you select Preferences -- after that it runs for couple minutes and destroys your panel etc.)

What happens, in fact, the first time you run it and select some options (I know only one -- Preferences), it resets all the values to some default once incompatible with the Unity and Ubuntu 11.10 system. I do not know if this happens to everyone and under what conditions but this happened to me all the time I run ccsm on a new install.

If you run ccsm the first time, go to Preferences and wait couple minutes till it ends destroying everything around (the panel should disappear). Then either click Back in ccsm and manually set up all the plugins to the values you like (do not forget to check the Unity plugin), or import your profile from the Ubuntu 11.04. Either way, the next time you run ccsm, it stops destoying anything.

P.S. I have personally changed this key to < Alt >< Super >Button1 in CompizConfig. It works perfectly. BUT, I could not find a file containing this string in ANY folder starting with dot '.' in my home folder. I could not find it in dconf-editor either. So, I have no idea how to change this without CompizConfig.


You might want to check under /apps/compiz-1/ with gconf-editor.

  • Where do i have to disable alt-LMB (left mouse button) and what do i need to enter there? Oct 26 '11 at 22:00
  • I tried to deactivate it in /apps/compiz-1/plugins/move/screen0/options/initiate_button. It was set to <alt>button1. I deleted <alt>button1 and made a reboot. But nothing changed, same behaviour. Oct 26 '11 at 22:09

If using Unity, hit Alt+F2 and go: System Settings -> Keyboard -> Shortcuts. If using Gnome, can't remember the exact path but it would be something like System->Preferences->Keyboard Shortcuts.
