dnd pointer lock when dragging tab between two gedit instances

Thank you for your bug report, I can confirm the issue there

@Gerd
Can you make a screencast please?

Is there anything you want from the screencast andrea? I can reproduce here, the mouse pointer changes to an hand when the drag start but something seems to stop the dnd on its way, the widget stays floating and stop moving and the mouse cursor stays stucked in grab state

you need to start the 2 instances from different ways, i.e one from the unity launcher and one from nautilus by clicking on something for example

Ok now i can reproduce it, but I'm not sure if it's a unity bug. There is a freeze problem with unity dnd and web browser that looks like this, but i'm quite sure this is not the same.

I can reproduce it in Gnome Shell too... I am now even more secure that it's not a Unity bug.

Thanks Andrea, closing the unity components, I though it might have to do with the launcher reveal but seems not

If he had anything to do with the launcher reveal, the freeze would be temporary. If it was a unity crash, killing gedit would not solve the freeze.

*If it had...

Thank you for your bug report. This bug has been reported to the developers of the software. You can track it and make comments at:

I added comments on GNOME bugzilla, but I have more comments relevant to just Ubuntu.

When this locks up, there is almost no way out for me. Ctrl+Alt+Backspace hasn't worked in a long time, so that's not an option. Ctrl+Alt+1 (or 2-6) works, but because of some other bug (NVIDIA, perhaps) the VT is invisible. (I also get a sort of "backlight bleed" effect sometimes.) The VT is present so I can log in and `killall gedit`, but I have to do it blindly. There's also no sshd by default, so I couldn't even log in remotely to kill the process.

There needs to be a way for a user who doesn't know these tricks to get back to working system without pulling the power.

I think this is the same bug:

The comments mention it could be related to a mismatched DISPLAY environment variable.

    - Revert symbolic icon search changes from 3.4.2, it breaks the icon
      displayed in indicator-power because of the order the icons are searched
      in. It looks like ubuntu-mono should drop the old icon names and
      use the new -symbolic icons. We need to carry this patch until
      ubuntu-mono fixes it's handling of symbolic icons. (LP: #1001229)
