compiz crashed with signal 5 in g_settings_get_value()

[Jussi Pakkanen]

After upgrading to newest quantal packages, I get this when logging in. Respawning Compiz does not work so this bug makes Unity unusable.

try this: dconf reset -f /org/compiz and then relogin, see if that helps.

Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

the error here is: "Settings schema 'org.compiz.unityshell' does not contain a key named 'devices-option'"

it's weird though because there is no 'devices-option' used in the current unity's codebase ... what version of unity is installed (dpkg -l | grep unity)

6.6.0-0ubuntu1

I tried recompiling the schemas with 'sudo glib-compile-schemas /usr/share/glib-2.0/schemas' but it did not help.

[Jussi Pakkanen (jpakkane)]

This has something to do with user configuration. If I create a new user account, login works for that account.

[Jussi Pakkanen (jpakkane)]

Deleting all compiz config directories in ~ and ~/.config fixes the problem. I expect this to bite many upgraders, though.

[Omer Akram (om26er)]

Jussi, just curious did you try reset -f /org/compiz (comment#6) when the issue was happened?

[Daniel van Vugt (vanvugt)]

Why is this no longer a duplicate of the original bug 1044662?

[Launchpad Janitor (janitor)]

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

@Omer Akram: dconf reset -f /org/compiz and relogin did not solve the problem, unity still doesn't start.
