If you have a folder 'bitcoin-0.7.0-linux' that means that you have successfully downloaded and extracted the 0.7 version. Click on that folder -->bin-->32 (or 64 if yours is 64)-->bitcoin-qt
Voila: clicking on bitcoin-qt will start bitcoin.
To put an icon on the Desktop:
' sudo apt-get install --no-install-recommends gnome-panel '
and then:
' gnome-desktop-item-edit ~/Desktop/ --create-new '
In the poppup you have to name the new folder (I suppose Bitcoin) and enter the command on the proper line which is the path to your folder -->bin-->32 (or 64 if yours is 64)-->bitcoin-qt
And Daily one , minimizing to the side launcher and bringing it back should also work. When you bring it back you have to move the cursor all the way to the top and you can chose from 'Files , Settings and Help' .
Thanks for the help, but I just upgraded from the Synaptic Package Manager. Still, minimizing and reopening Bitcoin doesn't bring up the toolbar. Yes, I take my cursor to the very top, and still nothing.
