GTK apps freeze if non root in kubuntu raring

You can ignore the fontconfig stuff.

As for libcanberra causing Gtk+ apps to lock up...that's truly weird. Not sure what to think about that one!

Experincing same issues but libcanberra-gtk-module is not installed on my machine

It might be helpful to start a console session immediately after logging in and running top. Keep the console visible so you can see what processes are being used. When you experience the problem, note what processes are taking up the most CPU and/or memory.

Hi caryb.

Have you tried disabling gtk events?

Input these lines in ~/.gtkrc-2.0:

gtk-enable-event-sounds = 0
gtk-enable-input-feedback-sounds = 0

Am trying this now, will give feedback.

Thanks Cary

I'm still experiencing this regularly, and haven't been able to narrow down a cause or even reliable steps to reproduce. It seems to happen at random whenever my GTK apps don't have focus.

I have follows the other suggestions: my .gtkrc-2.0 contains

# File created by KDE Gtk Config
# Configs for GTK2 programs 

include "/usr/share/themes/oxygen-gtk/gtk-2.0/gtkrc"
style "user-font" 
{
        font_name="Ubuntu"
}
widget_class "*" style "user-font"
gtk-font-name="Ubuntu 9"
gtk-theme-name="oxygen-gtk"
gtk-icon-theme-name="oxygen"
gtk-fallback-icon-theme="default"
gtk-toolbar-style=GTK_TOOLBAR_ICONS
gtk-menu-images=1
gtk-button-images=1
gtk-enable-event-sounds=0
gtk-enable-input-feedback-sounds=0

I have also removed the libcanberra-pulse -- it was suggested to remove libcanberra-gtk-module and I removed anything that kind of matched that name. (libcanberra0 seems to be quite important and half of the KDE desktop would be removed with it.)

I've noticed that Firefox and Thunderbird always seem to freeze together, and aren't using any CPU after doing so.
