Alt+PrintScr does no longer work to produce a screen capture of the active window

[David Planella]

I've just noticed that the traditional key combination to do a screen capture of the currently active window no longer works in Quantal.

Pressing PrintScr on its own still works for capturing the whole screen.

try this:

$ dconf reset -f /org/compiz/
$ unity --replace

and let us know if that fixes the issue.

Thanks for the suggestion. I tried it and it seems it didn't do any
change. Do I need to log out and back into the session for it to have
effect? (I didn't do that)

 status:new

Status changed to 'Confirmed' because the bug affects multiple users.

[Roman Yepishev (rye)]

When I try to remap the Alt+PrintScreen in gnome settings this results in "Mod2+Alt L".

According to xmpdmap -pm, mod2 is Num_Lock (0x4d)

This looks like it was fixed when bug 1050796 was fixed.
