I'm using the the gnome flashback session (metacity) in Ubuntu 14.04.
The default theme is the ambient theme. If you set a gnome panel to not expand, the handles are looking ugly:
How can I theme/change this?
1 - install ubuntu
$ sudo add-apt-repository ppa:tualatrix/ppa
$ sudo apt-get update
$ sudo apt-get install ubuntu-tweak
2 - find & configure
Go to app search look for 'ubuntu-tweak' .
Open it then .
go to tweaks .
Then Unity .
Make it comfortable 'read then edit'
if that didnt workout with you try to reset unity then configure it
reset unity
$ unity-reset
$ setsid unity
