CompizConfigSettingsManager made launcher panel disappear

Asked by Shawn

Ubuntu help recommended installing CompizConfigSettingsManager (ccsm) from the software center in order to adjust size of icons in the launcher panel. While I was exploring the contents of the ccsm, the launcher panel along with all of the items at the right side of the top panel (power, date and time, vol control, etc.) all disappeared, even though I did not click to change anything while in the ccsm. Now I cannot access the launcher panel at all. It does not appear when cursor is moved to left side of screen, and pushing the meta button does not bring it up. How can I recover my launcher panel and other items? I can get to bookmarks, but I cannot access any applications (including the ccsm). My OS is Ubuntu 11.10.

Try to do this:
1. Login into Ubuntu
2. Open a terminal by hitting CTRL + ALT + T
3. Insert and run this command:
gconftool-2 --recursive-unset /apps/compiz-1
unity --reset

4. Restart, this should work.

If when you hit CTRL + ALT + T and nothing happen, do this:
1. At login screen select Unity 2D as default session
2. Open a terminal
3. Insert and run this command:
gconftool-2 --recursive-unset /apps/compiz-1
unity --reset

4. Restart, this should work.

There're still several bugs against compiz and ccsm where playing with plugins leads to instability. Don't hesitate to confirm or reporting if you find a new one, thanks.
e.g.
Bug #773141
Bug #880679

Terminal came up but it said: "Command 'gconftool-2' not recognized.

Problem persists: CompizConfigSettingsManager made launcher panel disappear along with all items in upper right corner of top panel. I attempted solution recommended by Enrico Carafa as below:
Try to do this:
1. Login into Ubuntu
2. Open a terminal by hitting CTRL + ALT + T
3. Insert and run this command:
gconftool-2 --recursive-unset /apps/compiz-1
unity --reset
4. Restart, this should work.

Now, I entered the command as: gconftool-2 --recursive-unset /apps/compiz-1 unity --reset
I don't know if the "unity --reset" was supposed to be on same line, but nothing happened. When I entered it on a separate line or just alone, a lot (and the same thing) happened within the terminal box, but after rebooting nothing changed. Don't know if I was supposed to space differently or something, but I still need help.

As posted in #4, each one is a single cmd.

If they don't help, #2 already mentioned bug 880679
Try:
Login to Unity-2d, enable Unity-plugin in CCSM, log back in to Unity-3d session (Ubuntu).

If there is still nothing displayed, open CCSM via terminal:
ccsm

and enable Unity-plugin if it isn't.

As one can view from output of 'ccsm', it's backend is gconf, if it isn't installed 'gconftool' does nothing.
Packages are:
gconf2
gconf2-common
gconf-defaults-service
gconf-editor
