launch panel disappears

Try:

gconftool --recursive-unset /apps/panel && killall gnome-panel

terminal says 'gconftool process not found'.

Maybe it is important to say that this is what happened:
- upgraded to 11.04r
- opened 'compiz advanced desktop effect settings and configured it
- program blocked, all panels blocked, mouse pad blocked
- performed a reboot
- no more panels in unity, classic view works fine

I guessed there was a bug with 'compiz Advanced desktop effect
settings', so uninstalled it, but it didn't help.

Copy/paste commands of actionparsnip and don(t type them. I presume you made a type. To paste on terminal, use Shift+Ctrl+V instead of Ctrl+V

To clarify
## Ubuntu session
Unity has a 'launcher' on left side and one panel on top.
https://help.ubuntu.com/11.04/ubuntu-help/index.html

## Ubuntu-classic session
Gnome can have two panels on top and bottom.

Reading your comment #2 issue, playing with CCSM (compizconfig-settings-manager) and
> no more panels in unity
refer to suggestions there.

Dears

_in unity_
ctrl + alt + T keyboard combination does not work to launch terminal,
ctrl + alt + F2 combination works to launch terminal lookalike (login
and password are asked which is normally not the case with the teminal),
however proposed solution to paste the command line (ctrl + shift + v)
does not work.

_in classic view
_It is possible to paste the command line into the terminal, but it
changes nothing to the problem in unity.

Tx for helping me out.

This is a tty (virtual console, text mode only).
If ctrl+alt+t doesn't work to open a terminal, try alt+f2, type: gnome-terminal, hit [Enter].
Try this.

Anyway tty is better to repair something and not making it worse.
If unsetting panel configuration, as command suggested above, didn't help it might take a little more.

To exclude user misconfiguration create a test-user, login and verify if the issue remains on a clean user account.
If the issue isn't in test-user, unfortunately, unless you remember which recent changes have been made in order to revert them, you could move .gnome2 and .config, which means some user defined configurations will be gone and you have to start from scratch.

Close all GUIs and save your work.
Switch to tty (virtual console, text mode only): ctrl+alt+f1
Login with username and passwd.

## To move (backup) .gnome2 and .config type:
mv ~/.gnome2 gnome-backup
mv ~/.config config-backup

sudo reboot

## The *-backup directories will be in your /home/user, where, if necessary, contents successive can be reimported from.

To restore Unity.
Save your work and close all GUIs.
Switch to tty: ctrl+alt+f1
Login with username+passwd.
Type:
unity --reset
sudo reboot

If there is still no decoration after login, try again tty: ctrl+alt+f1
unity --replace

## But this time switch back to desktop: ctrl+alt+f7
