Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Let's say I have Gthumb open, and then launch Nautilus from the Unity launcher (in 12.04). Why does it sometimes not focus the mouse on Nautilus, which I just launched? Instead, the focus remains on Gthumb while Nautilus opens in front of Gthumb (and not being focused on).

Is this correct behaviour?

I wonder how can Ubuntu be released with such a critical bug. After trying to close the wrong application twice because of this bug (the close button is global/shared for maximized windows), I won't try Unity again until it's fixed (well, it's more likely that I won't ever try Unity again, but who knows...) –  marcus Jun 25 '12 at 2:52

You can configure it with CompizConfig-Settings-Manager.

1) Install it: sudo apt-get install compizconfig-settings-manager,

2) Open ccsm (Alt + F2 and type ccsm and hit Enter)

3) Go to "General Options" > "Focus & Raise Behaviour" and set "Focus Prevention Level" to "Off".

4) Enjoy ;-)

If you are feeling lazy, just paste this at terminal and you're done:

gconftool-2  --type=Integer --set /apps/compiz-1/general/screen0/options/focus_prevention_level 0

I've done this and will test it over the next day or or so. So far so good... –  Gonzoza May 3 '12 at 5:24
    
At 14.04, the path for focus_prevention_level in the command line to gconftool-2 is /org/compiz/profiles/unity/plugins/core –  Rael Gugelmin Cunha Apr 25 at 14:33

No it is not correct behavior. The answer to the question "why is it happening" is because there is a bug. I suggest submitting a bug report. Surprisingly I cannot find an existing bug report for this, though I can confirm that it does happen. Post a link to the bug when you have done it so I can attach myself to it.

Edit: Found it. Bug #781931 Not sure why this answer has been down voted as it is certainly the answer to the question of why this happens. The work around using ccsm is not an answer to the question, it is a workaround for the bug. That in itself is very useful and worth posting but it does not answer the question that was asked.

Well, the Compiz answer seems to have made the correct difference. –  Gonzoza May 4 '12 at 11:02

The point is that question you asked was "Why does it sometimes not focus the mouse on Nautilus", not "How to make it correctly focus on Nautilus" so the correct answer to the question you asked is that it is a bug. No doubt the workaround is very useful but it is not the answer to the question you asked, it is the answer to a different question. –  clanlaw May 4 '12 at 15:16
