Re: [Ayatana-dev] Breakage with latest compiz

[Sam Spilsbury <smspillaz@xxxxxxxxx>]

Just so that everyone knows what's going on here

1. There's a bug which I'm currently tracking down in gtk3 where calling gtk_init_check more than once from different dlopen ()'d libraries in certain circumstances will cause gtk to crash

2. Both the unity shell and slate style dialogs plugin require gtk in order to get theme information

3. gtk_init_check must be called at /least/ once before you do that

4. For debugging purposes, either one or both plugins could be enabled

5. We can't call gtk_init_check twice in the case that both are enabled, but we must call it once

6. We can't check if gtk_init_check has been called already by another plugin

7. The interim solution was to make a /new/ plugin which calls gtk_init_check and is loaded first

8. We can't dynamically add depended plugins at runtime (only through ccsm which needs to be fixed in libcompizconfig)

9. People who have changed their settings and then don't enable gtkloader are in for some crashes

10. As such, we're now moving this into a distro-patch in compiz for the time being

11. If you previously had this plugin enabled then you need to disable it since it would cause 1. to happen

Thanks everyone and happy upgrading :)

Hey everyone,

If you run unity from trunk and are using oneiric, you probably enabled a couple of days ago the "gtk loader" plugin in cssm. If so, ensure to disable it after installing compiz 1:0.9.4+bzr20110606-0ubuntu5 on tonight's upgrade. This one is not needed and wil conficts (you will have the screen frozen).

Then, rerunning unity should work again ;)
Sorry for the inconvenience, there is no other way for a clean upgrade path for our oneiric user (we can't add plugins dynamically in compiz).
