Screen edge actions set in CCSM don't work (sometimes)

[Pierre-Olivier Megret]

I'm used to configuerate the top-left corner to switch in expo mode ( or desktop-switcher) . I use CCSM to set that and select/valid top left corner in CCSM / expo / bindings/ expo edge.

After setting it , top left corner works well but after reboot , it doesn't . Top left corner is inactive although it 's still selected in CCSM.

I have to deselect top left corner , valid new setting , reselect it and valid in order to activate it.

The Issue occurs after session logout too.

On My other computer I can't set the left corner anymore ... it's well selected in CCSM but doesn't work.

[Pierre-Olivier Megret (sorrodje)]

After today's update/upgrade ( done at 12:00 am today à I have still the same problem : CCSM doesn't keep my top left corner active after reboot although it's well selected in CCSM /expo .

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[mattubu (mattubu)]

I have the same issue. I have edge bindings set for Expo and Scale, but both are usually non-functional after a logout or reboot (sometimes one works, sometimes both work). The bindings need to be cleared and reset for them to work again.

I am running 11.10, but the issue existed in 11.04 as well.

[Pierre-Olivier Megret (sorrodje)]

Hi Mattubu

Problem was solved by activating proposed repos and upgrade ;)

Pierre-Olivier

[mattubu (mattubu)]

At thank you Pierre-Olivier. It does fix the problem. However, I downgraded to stable because I'm not sure I want to have proposed updates running on my main machine. But if it's fixed in proposed I'm looking forward to an update soon!

[DJ (ke7mbz)]

A faster way to fix it is do a compiz --replace, rather than manually resetting the bindings.

[DJ (ke7mbz)]

The problem seems to be solved now. But I'll wait and see.

[Pierre-Olivier Megret (sorrodje)]

Yep Solved on my two computers

[matthieu vidal (mvidal0001)]

I've discovered this problem after upgrading to 12.04 alpha (unity 5.4).

The setting I have made with ccsm (since unity 4 ... then unity 5.2 ...) is :

Top Left --> scale plug-in (this setting gave me the behaviour of gnome-shell).
Top Right --> expo plug-in .
Bottom Left --> Dash trigger (by the way I'm not able to do that any more so I use the lowest value of the new parameter : "reveal sensitivity" in the appearance/Behaviour panel ).

The first anomaly (using ccsm) is that "Top Left setting" for "scale or expo plug-in" is not exclusive with "Top Left" setting for dash in Unity plug-in (reveal Trigger).

I have to execute 'compiz --replace' if I want the "Edge trigger system" working both for "scale plug-in" and "expo plug-in".

[matthieu vidal (mvidal0001)]

compiz (1:0.9.7.0~bzr2995-0ubuntu5) precise;
unity (5.4.0-0ubuntu2) precise;

this problem is still there

[matthieu vidal (mvidal0001)]

This problem is gone with precise beta 1

^_^

I don't have any clue what's the package which corrected it.

[matthieu vidal (mvidal0001)]

and today the problem is still here.

[matthieu vidal (mvidal0001)]

and again with new version of compiz

[matthieu vidal (mvidal0001)]

and again ...

[matthieu vidal (mvidal0001)]

no change with new compiz version ...

[matthieu vidal (mvidal0001)]

In fact this bug indicates that the integration between compiz and unity is clearly a big mess ...

[Tyler Wagner (tyler)]

This problem definitely persists in Ubuntu 12.04 final. "compiz --replace" is the fastest solution. Try making it autostart.

[Tyler Wagner (tyler)]

This problem definitely persists in Ubuntu 12.04 final. "compiz --replace" is the fastest solution. My solution is to create a script that does this:

#!/bin/sh
sleep 5
compiz --replace

Name it something, make it executable, and create a "Startup applications" shortcut to auto-launch it on login.

Lessons learned:
1. Do not try to do this in .gnomerc (which runs before Gnome starts)
2. Do include the sleep invocation, or it has no effect

[Sebastien Bacher (seb128)]

is the issue specific to unity sessions or does it happen in GNOME classic as well?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[matthieu vidal (mvidal0001)]

A solution ? 4 month I have to restart compiz ....

[Doug McMahon (mc3man)]

I've un-duped my 12.10 bug on this because it only happens in 12.10 not 12.04
In the case of 12.10 top/bottom corner bindings become non-functional on a restart unless the flip left & or right binding(s) in wall or cube are disabled
Maybe 12.10 does some conflict resolution on a fresh start & incorrectly sees the corners as a conflict?

[karl (karl-sebastian-liebich)]

for me the bug occures also in 12.04 not only in 12.10. And sometimes only scale is affected, expo is not. No matter which corners I configure (not only top left).

[dbius (danubiusz)]

Guys give a chance to this workaround: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/858845/comments/3

It worked me under Ubuntu 12.04.1

[karl (karl-sebastian-liebich)]

the workaround posted by dbius works for me, too, under 12.04.1

[karl (karl-sebastian-liebich)]

..and under 12.10, (of course)..

[Daniel van Vugt (vanvugt)]

I think I've found a test case that breaks my corner binding:

1. Load the grid and expo plugins.
2. Test that dragging windows to the top-left corner triggers grid.
3. Enter expo mode (top-left corner or Super+E)
4. Try to drag one of the windows to the top left corner of the screen. It won't get that far, but make sure the mouse gets to the corner.
5. Exit expo mode (Escape or Super+E)
6. Try dragging a window to the top left-corner again.

Expected: Grid to trigger.
Observed: Nothing.

[karl (karl-sebastian-liebich)]

when moving my home I did not copy all of the config-files and discovered the workaround https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/858845/comments/3 does not work anymore. There is no /apps/compiz-1/general/screen0/options/active_plugins key in gconf-editor it seems to be in /apps/compizconfig-1/profiles/Default/general/screen0/options but no unityshell is listed in active_plugins..

[matthieu vidal (mvidal0001)]

It's getting worse and worse with Quantal 12.10 Beta : executing "compiz --replace" or "unity --replace" freeze the session without a window manager ....

boring ...

[MC Return (mc-return)]

On Quantal with recent Compiz/Unity trunk I cannot reproduce this anymore. Corner bindings always work, except for those that do not work because of bug 1011167.
