there is no direct or simply way to configure what we need in question.
But it can be done by editing the User Shell theme that is in use.

if you are using default theme in 18.04, below is the way to achieve.

first take back up of /usr/share/gnome-shell/theme/ubuntu.css file.

now open the file with you favorite text editor, mine is gedit, so

sudo -H gedit /usr/share/gnome-shell/theme/ubuntu.css

go to line number 1205 and find the below content.

.dash-label {
  border-radius: 7px;
  padding: 4px 12px;
  color: #eeeeec;
  background-color: rgba(46, 52, 54, 0.7);
  text-align: center;
  -x-offset: 8px; }

Change it to 

.dash-label {
  border-radius: 7px;
  padding: 4px 12px;
  color: #eeeeec;
  background-color: none;
  font-size: 0pt;
  text-align: center;
  -x-offset: 8px; }

save the file & close. Reboot to see the change.

enter image description here

if you use different User-Shell themes, you may find same content and editing it as above.

  • @PRATAP, very nice touch. Probably you best recommend to edit the original file, which is /usr/share/gnome-shell/theme/gnome-shell.css. All other files link to that one. Yet, the header of the file says " do not edit because the file is generated. There might be a better and more persistent way to effectuate the change (aka editing another file). Yet, for now, the hack may do the job.

  • is it possible to set a timeout instead of completely hiding the tooltips?

sudo vim /usr/share/gnome-shell/theme/ubuntu.css

or

sudo nano /usr/share/gnome-shell/theme/ubuntu.css

or any text editor launched with sudo..

Search: .dash-label

You will see something like:

.dash-label {
  border-radius: 7px;
  padding: 4px 12px;
  color: #eeeeec;
  background-color: rgba(0, 0, 0, 0.7);
  text-align: center;
  -x-offset: 8px;
 }

Backup it. Then replace or comment with /* ... */ old and add:

.dash-label {
  font-size: 0;
 }

  • Somme tweak tools, extensions can use backup css + some themes can use different names and path's.
