ability to re-enable scroll-wheel desktop switching in compiz

This one is very frustrating.
I have moved to Kubuntu Karmic as that allows changing desktop with the scroll wheel
Hopefully the paper cut guys dont move to Kubuntu next.
Was a nice excuse to play with KDE4.3 :)

If the shortcuts are not working properly when re-enabled , it is a bug in Compiz and not a papercut.

mac_v: The reason I added the papercut project was because this is a result of the patch applied to compiz by the papercut project, and I thought they should know about this regression which was untested.

@Saïvann Carignan:
Could you take a look at this.

More info:

After talking with mac_v on IRC he suggested to search gconf for "scroll_enabled" which on my system did not produce any results. These leads us to the idea that the gconf was deprecated.

Saivann: I can't find the code that you linked to from the original bug report to disable this by default, no I'm not even sure what the change was that was made. The link that doesn't work: https://code.launchpad.net/~saivann/compiz/mousewheel_disabled

Hi there, yes the branch was deleted, however you can see the diff between 1:0.8.2-0ubuntu13 and 1:0.8.2-0ubuntu14 in the compiz history :

https://launchpad.net/ubuntu/+source/compiz

The only difference applied here is to set these gconf options to "Disabled" by default :

/apps/compiz/plugins/vpswitch/allscreens/options/prev_button
/apps/compiz/plugins/vpswitch/allscreens/options/next_button

However, this is the system wide configuration so it should still be possible to change this option for the current user without root access, whether with gconf-editor or ccsm.

Did you try to open ccsm in the "Viewport switcher" section, "Desktop-based Viewport switching" tab and to enable "Move next" and "Move Prev", choosing Mouse Button 4 and Mouse Button 5?

That is the problem, when one goes into ccsm and tries to change the tabs to enable "Move next" and "Move Prev", choosing Mouse Button 4 and Mouse Button 5, they wont stick. It changes it right back to disabled while one is still on the ccsm viewport switcher options.

If one choose say "ctrl button 4" and "ctrl button 5", then it sticks perfectly.
But changes desktops and having to push the control button and the mouse scroll is then a inconvenience.

Thanks for looking into it for us

Ok, booted back into Ubuntu gnome, can report: The correct wording is
"Control Button5" (not "ctrl Button5" like I said earlier)
That was just a typo in this bug report while reporting it from Kubuntu.

What I can say is, if I go into Gconf editor and find
/apps/compiz/plugins/vpswitch/allscreens/options/prev_button and
change that to "Button 4", then it sticks and works fine.
If I then open ccsm and went to these settings and disabled "Button4",
then tried to set it back to Button 4 again it would not stick once
again.

So the temporary fix is to use gconf-editor to make the changes stick
and not try do it from within ccsm, until a fix is found for that
method.

This will do fine for me for now, thanks Saïvann Carignan for the info.

What happens when using ccsm to configure Button5 and Button4 is that the map ~/.gconf/apps/compiz/plugins/vpswitch is deleted!

I guess this is the reason why those two buttons then become inactivated. The workaround using gconf-editor to set Button5 and Button4 works for me too.

I also see/can confirm the behavior described by habtool and Bowmore. It seems we probably have enough information to consider this bug triaged.

ubuntu-sponsor for main : I attached two branchs which replace the previous fix for bug #147230 with a more appropriate one that fixes both bug #147230 and this bug. The problem was simply that ccsm was not able to change system-wide default gconf values, even only for the current user. The old fix is removed and new fix simply update compiz gconf schemas so ccsm now consider that

/apps/compiz/plugins/vpswitch/allscreens/options/prev_button
/apps/compiz/plugins/vpswitch/allscreens/options/next_button

are disabled by default, but can be re-enabled at anytime by the user. I tested this new fix to make sure that it works correctly with ccsm and gconf.

Thank you very much, Saïvann, the fix you describe should please everyone while not reverting the fixed paper cut.

Quick update

This regression is still in effect under Karmic Alpha5.

Cant get these two settings to stick in CCSM, only via gconf manually.

I uploaded the fixes for this into the compiz PPA. There is a feature freeze exception request for compiz from the PPA to karmic pending. If that is granted, the patch will automatically flow in, if not it needs to get merged seperately again.

This bug was fixed in the package compiz - 1:0.8.3+git20090914-0ubuntu1
