3) don't sho the warning

4) when the system start up i can see a windows with the follow 'warning ....' i cant' see all because the windows desapeer to fast but it is the same windows message when you try to activate avant-window-manager without compisite efect i mean compiz activate, i'm sure what i have got a composite efect activate at start-up maybe the avant-windows-manager try to activate before compiz.

[Julien Lavergne (gilir)]

I think it's because the avant-window-navigator start before compiz. I guess you try to autostart avant-window-navigator. Do you add it manually or using the option in the manager ?

[hhlp (hhlp-deactivatedaccount)]

well you are right julien for some reason in the update process the avant-window-navigator add a extra launch in system -> preference -> startup aplicacions i delete that extra launch and all fine so i have a question why don't say awn is already started..

now you can close the issue

[hhlp (hhlp-deactivatedaccount)]

it happended again i unistall avant-window-navigator trying to resolve and install again but it still happened

[ichudov (igor-chudov)]

I have the same problem.

This is because the window manager really is NOT composited.

Go to your System/Preferences/Appearance/Desktop Effects and check. They are set to NONE if you have the same problem as me.

The real problem is that they can no longer be changed to something else, something lost the capability to run a compositing manager.

It is a regression, as I was previously able to run a compositing manager.

[Daygan (sheerzeal)]

hmm.. ichudov, you're right - it seems that when I try to change my desktop effects back to normal or extra, I get the message "desktop effects could not be enabled" and yes, of course, I do have this same AWN problem. I will note that I have another computer with which I do not have this problem at all and have also updated to Ubuntu 9.04 on that one. Also, when I turn on the compiz fusion icon and select "reload window manager" the awn problem is solved, as is the Desktop Effects issue. I have not, however, yet been able to fix this problem without manually reloading windows manager. I'll have to see what is different between my home computer (problem-free) and my laptop which has this problem.

[Julien Lavergne (gilir)]

It's seems more a drivers/window-manager problem than an Awn problem. Actually, this warning is a normal behavior of Awn. The goal is to warn the user that there is a problem in his configuration.

[qetuR (petur-hjartarson)]

Had the same problem, and should it not be enough to just try to fix the compositing manager?

If you run Gnome, your default window-manager is Metacity, right? On this link: http://wiki.awn-project.org/Installation#Installing_Avant_Window_Navigator I found a fix for Metacity.

"Metacity: The default window manager for Gnome. Compositing support was started for this WM in November 2003 (around version 2.7.0), but it has never been very stable. Because of this, it is not enabled in most distributions. Recently though, work started on a new implementation for compositing support that is in version 2.22.0 (and later). To enable the compositing manager, you need to use the "Configuration Editor", AKA gconf-editor, to set the key /apps/metacity/general/compositing_manager to true (i.e., the box must be checked). "

To enable the compositing manager, you need to use the "Configuration Editor", AKA gconf-editor, to set the key /apps/metacity/general/compositing_manager to true (i.e., the box must be checked). "

Sorry for the question:
How would one start the AKA gconf-editor in order to check the box in the metacity compositing manager?

[qetuR (petur-hjartarson)]

Just write gconf-editor in the terminal.

But be carefull, you can change alot of things in there that oyu don't want
to change.

Cheers!

There are three ways to enable Metacity's compositing manager:

1. (Requires Jaunty, I think) Press Alt-F2 and run (without quotes) "metacity --composite --replace"
2. Click the "Applications" menu, navigate to "System" or "System Tools", and run "Configuration Editor". Navigate to the /apps/metacity/general folder and make sure the "compositing_manager" checkbox is checked.
3. From a terminal, run (without quotes) "gconftool-2 --set /apps/metacity/general/compositing_manager --type=bool true"

[Daygan (sheerzeal)]

okay.. that didn't really fix things for me.. well, maybe it fixed about 50% of the problem.

I tried qetuR's method, checked the box, removed my workaround to force-start compiz at startup, and then restarted my computer. I suppose metacity's compositing manager started properly, or at least it didn't give Avant Windows Manager any major problems, but suddenly I had 4 desktop spaces instead of two.. and Extra visual effects options was still not available - nor was "Normal".

After starting the compiz fusion icon, selecting compiz as opposed to metacity, and restarting the windows manager, things were back to normal, but still, that's just a workaround. I'd like the actual solution.. I'll keep looking into it...

[Daygan (sheerzeal)]

correction - I also had to select compiz fusion icon->compiz options > loose bindings before the problem was entirely fixed. After that I could deselect "loose bindings" and it was still okay..

[Mark Lee (malept)]

I should note that the "Visual Effects" tab is not affected by switching Metacity's compositing manager on or off, as it is a Compiz-centric preferences pane.

Also, FWIW, it's called "Avant WIndow Navigator", not "Avant Windows Manager".

[Mark Lee (malept)]

Sigh. Sticky Shift key. "Avant Window Navigator", also abbreviated "Awn".

[Daygan (sheerzeal)]

ah yes - "Avant Window Navigator". too impatient to finish writing to check the proper name. sorry..

[Daygan (sheerzeal)]

so, it would seem that this is a problem with compiz not starting properly at startup. does anyone know how to resolve this problem without a workaround?

[Mark Lee (malept)]

Probably a better place to ask that question would be either the Ubuntu Forums or the Compiz Forums.

(Note: I don't run compiz.)

[Daniel (danbar)]

I wish to say a special thank you to Mark Lee. Besides providing me with the right answer he gave me three choices. And it was very easy to follow the directions. He is superb!

[Daniel (danbar)]

If I need to revert the command in Terminal what do I have to do?

The command was:

From a terminal, run (without quotes) "gconftool-2 --set /apps/metacity/general/compositing_manager --type=bool true"

I found that for some operations I need to revert this command.

[Mark Lee (malept)]

Because I'm feeling a bit lazy, here are the instructions, but in reverse.

There are three ways to disable Metacity's compositing manager:

1. (Requires Jaunty, I think) Press Alt-F2 and run (without quotes) "metacity --no-composite --replace"
2. Click the "Applications" menu, navigate to "System" or "System Tools", and run "Configuration Editor". Navigate to the /apps/metacity/general folder and make sure the "compositing_manager" checkbox is unchecked.
3. From a terminal, run (without quotes) "gconftool-2 --set /apps/metacity/general/compositing_manager --type=bool false"

Thanks!!

I was not able to start AWN. After configuring and enabling the Compositing manager, it worked. However, then my visual Effects stopped working. I didn't make the connection between the two. I stopped the compositing manager and now the effects work again.
