22.04 : Default screenshot utility can be triggered from login-screen but useless.

[Coeur Noir]

Hi,

Ubuntu 22.04 ( Gnome, GDM, Wayland )

Hitting « PrintScreen » key in login-screen launches default « new » screenshot utility.

It seems to work, at the end it says « picture has been saved in the paperboard ».

But how get hands on that paperboard later ?

No picture is saved in /root.

I suspect the screenshot utility should not be launch-able from login-screen,

as it suggests something impossible to do ( get a screenshot of login-screen. )

After that, when you log in into a session you might believe you have some picture to paste, and it seems it's not the case :

Gimp will say there's no data to paste from paperboard.

So I expect one of these two things :

⋅ make the screenshot available to paste in regular session

or

⋅ make screenshot tool NOT available in login-screen.

I can't seem to reproduce this. There is no screenshot feature available in the login screen. Are you sure you don't have any extensions installed?

Even if it did work, you should expect screenshots to appear in ~gdm, not ~root

Wait…

…today I don't have this behaviour.

Hitting printscreen key while in login-screen just does nothing.

Yesterday it triggered the screenshot utility each time I tried.

What a joke !

[Daniel van Vugt (vanvugt)]

No problem. The bug will expire automatically after 2 months if there are no further comments.

In future before reporting a bug against gnome-shell, please try deleting your local extensions first:

  cd ~/.local/share/gnome-shell
  rm -rf extensions

to confirm they are not to blame.

[Coeur Noir (coeur-noir)]

In the eventuality it happens, ok.

Might be interesting though to know how / why it happened.
