Missing task bar in Ubuntu 14.04
« on: October 03, 2014, 04:44:12 pm »
I am looking after the computing needs of an old chap who is running Ubuntu 14.04 on a Toshiba A300D. 
I didn't notice at installation that the task bar (at the bottom of the screen) is present but empty.  This means that it is awkward to see what processes are running, except by using Alt-tab, which the owner keeps forgetting. 

I have tried     sudo apt-get install --reinstall ubuntu-desktop      which I found on the web, but to avail.  Any ideas, anyone?

Have you tried RIGHT clicking on the panel to see if anything appears?

Oh, dear - I'm  not doing very well, am I?   
I ought also to have mentioned that the PC is running in gnome fall-back mode!     I wonder what other key info I've forgotten to mention!

What happens if you run:
Code: [Select]
sudo mv -v ~/.gconf/apps/panel ~/.gconf/apps/panel-old
then log off/on ?

Response:   
[sudo] password for user:
mv: cannot stat ‘/home/user/.gconf/apps/panel’: No such file or directory


so I didn't bother logging off/on.

[EDIT]

Before carrying on below .. what happens if you hold WinKey+Alt, and whilst holding them Right-Click on the bottom panel ?

[END EDIT]

OK, let's get really brutal with it...

Try:
Code: [Select]
mv -v ~/.gconf ~/.gconf-old
then
Code: [Select]
mv -v ~/.config/dconf ~/.config/dconf-old
then log off/on

any change ?

That worked a treat, Mark. 
But why does removing those files restore the task bar?   Presumably they are present for a reason.  Or are the missing files reconstituted because they are essential? 

[EDIT]  Just had a look and answered my own question!

Many thanks, as usual, Mark.  My mate will be very happy.

Yeah as you guessed, they're just configuration files for the user you're currently logged on as .. if you rename or delete them, they'll be recreated with the defaults settings after logging off/on.
