** Description changed: + Impact: + Using dconf profiles can lead to gconf keys to be overwritten with wrong values, it's especially impact some desktop settings and compiz + + Test Case: + + $ gconftool --set /desktop/gnome/sound/event_sounds --type bool false + $ gconftool --get /desktop/gnome/sound/event_sounds + false + + Then editing some file under /etc/dconf and running dconf update: + + $ sudo vi /etc/dconf/db/site.d/screensaver + $ sudo dconf update + $ gconftool --get /desktop/gnome/sound/event_sounds + true + + Regression potential: + Some of the gsettings could not be written back to gconf which could impact legacy applications which are still reading the gconf value + + ------ + This was tested in a fresh installed precise machine, with the addition of dconf and a particular dconf configuration. Settings set in gconf backend get overwritten when running 'dconf update'. This can be tested by changing any value in gconf to something different than the default: $ gconftool --set /desktop/gnome/sound/event_sounds --type bool false $ gconftool --get /desktop/gnome/sound/event_sounds false $ gconftool --set /apps/metacity/general/focus_mode --type string sloppy $ gconftool --get /apps/metacity/general/focus_mode sloppy Then editing some file under /etc/dconf and running dconf update: - $ sudo vi /etc/dconf/db/site.d/screensaver + $ sudo vi /etc/dconf/db/site.d/screensaver $ sudo dconf update $ gconftool --get /desktop/gnome/sound/event_sounds true $ gconftool --get /apps/metacity/general/focus_mode click After talking about this with Ryan Lortie, he suggested disabling the gnome-settings-daemon plugin: $ gsettings set org.gnome.settings-daemon.plugins.gconf active false $ gconftool --set /desktop/gnome/sound/event_sounds --type bool false $ gconftool --set /apps/metacity/general/focus_mode --type string sloppy - $ sudo vi /etc/dconf/db/site.d/screensaver + $ sudo vi /etc/dconf/db/site.d/screensaver $ sudo dconf update $ gconftool --get /desktop/gnome/sound/event_sounds false $ gconftool --get /apps/metacity/general/focus_mode sloppy It looks like the gconf plugin is overwriting all the settings with the defaults, thus losing anything the user had customized. It's quite likely that a number of other bugs "Compiz loses my settings" are actually caused by this plugin. Also, as instructed by Ryan, I tried removing /usr/share/GConf/gsettings /wm-schemas.convert and re-enabling the plugin, and then it doesn't override any values that are related to the window manager but it does override the one in the example: $ gsettings reset org.gnome.settings-daemon.plugins.gconf active $ gsettings get org.gnome.settings-daemon.plugins.gconf active true $ gconftool --set /desktop/gnome/sound/event_sounds --type bool false $ gconftool --set /apps/metacity/general/focus_mode --type string sloppy - $ sudo vi /etc/dconf/db/site.d/screensaver + $ sudo vi /etc/dconf/db/site.d/screensaver $ sudo dconf update $ gconftool --get /desktop/gnome/sound/event_sounds true $ gconftool --get /apps/metacity/general/focus_mode sloppy So, focus_mode didn't get overwritten while event_sounds did. One possible solution is to remove the wm-schemas so that compiz settings don't get lost. A better (but probably harder) solution would be to fix the plugin so that it doesn't overwrite what the user sets. Maybe just remove the schemas that are being modified and stored in gconf for Precise. I found out that to reproduce in a fresh installed precise machine, I had to set up some dconf files, then reboot, and then I could reproduce consistently as explained here. I'm attaching a bunch of dconf files. After unpacking, you need to run dconf update once to generate the db and then reboot. After that it should be reproducible.
