"Show Desktop" Screen Edge doesn't work anymore after recent update

[Bazon]

Binary package hint: compiz

1) release: 11.04
2) version: compiz 1:0.9.4git20110322-0ubuntu5
3) what I expect to happen: binding the function "show desktop" to the bottom tight screen edge corner works (as it did before)
4) what happened instead: it doesn't work any more. keyboard binding to super+d works still, but screen edge doesn't.

Same problem here. Actually, there does not seem to be any tab to activate edge/corners in compizconfig anymore. There was with ubuntu 10.10. Now only super+d triggers "show desktop".

[Ayzen (ayzen-quwe)]

I can confirm this bug too. I tried to bind left-right edges for switching between desktops, but that doesn't work in Ubuntu 11.04. I suppose it's a Unity bug...

[Bazon (bazonbloch)]

For me, it works again. whyever.

[Ayzen (ayzen-quwe)]

Have applied all updates, and still no luck with this... :(
Bazon, can you bind "left-right edges + left click" for switching between desktops (for example, in Rotate Cube). And try clicking on screen edges.

[Simon Junga (simonthechipmunk)]

Same problem with me.
Combining Screen Edge actions with mouse keys does not work for all Compiz plugins.
Firstly I suspected the grid plugin, because of the new win7 like functions, but disabling does not show any effect on this bug.
What's strange: Using Screen Edges without further keys does work!

I have just upgraded to 11.10 (actually I did a clean install but preserved my /home). I am trying to configure LeftBottom for expo plugin and RightBottom for scale plugin. It works at first but once I logout and login again it stops working. If I erase the settings in CCSM and reconfigure the settings work again until next reboot.

[Navaja (verschae)]

Same problem here in 11.10.

[iSlave (macslave)]

Same problem here ater upgrading to 11.10 from 11.04. No problems on 11.04, though...

[Alex (alevar)]

I had this problem. However putting compiz into the startup applications solved it.

Name: Compiz
Command: bash -c "sleep 3; compiz --replace"

Saw this solution somewhere else, but cant find the link
