Going to workspace adjustement automatically add keyboard shortcut for fade screen

[Bruno Beaufils]

As soon as I use Ubuntu Tweak Tool to adjust my workspaces size and even without actually doing it changes something in my system such that, on my laptop (MacBookPro10,1), the F9 key is no more usable. When I press on it, it toggles the screen fading (light to dark and vice versa).

The only way I find to disable the behavior is to remove all my gsettings and not use Ubuntu-Tweak-Tool anymore.

This happens only when visiting the `Adjust > Worskpace` window and no others.

When I use unity-tweak-tool I do not get this *very* annoying behavior.

Here is a diff of `dconf dump /` before and after using Ubuntu Tweak :

I am using Ubuntu 13.04 (up to date) on a MacBookPro10,1, and Ubuntu-Tweak 0.8.6-1~raring1.

Thanks for the report.

Yes, this is a known issue, the widget plugin will be enabled automatically. This should be fixed in the next version.

Do you know what is the cause of the issue ?

I asked the question because I filed another bug (#1190341) which disable me to control the backlight of my screen and since this one is able to fade the screen I would like to know how to use it to find a way to workaround if not a bugfix.

Because the "Show Widgets" option will check if the "widget" Compiz plugin is enabled, if not, it will enable it, and the F9 hotkey is the default hotkey to enable widget layer.

I've already removed the "Show Widgets" edge settings in Workspace, next version this issue will be fixed.
