When I download a file with firefox, it always asks me with what program I want to open it with, even when that type of file is recognized by the system, and I can double click on it in Nautilus and have it open properly.

This is an example with a deb file, which opens with Ubuntu Software center (as it should) when I double click on it in Nautilus.

I do not want to look for the required program in /usr/bin or whatever in the Firefox dialog, I want Firefox to recognize my system preferences. What I resort to doing now is choose "Download", open Nautilus and double click on the file...

Why can't Firefox recognize my system settings, and how do I get it to?

Thanks!

I'm trying to upload a folder of about 1.5 GB to Ubuntu One. Everything seems to be set up correctly, and Ubuntu One says "File sync in Progress".

However, all it does is use about 3.3 GB of RAM (!) and 100% of one core, without sending anything on the network (as reported by system Monitor).

It's been like that for about 15 hours now (I left it on through the night).

What is going on here?

I use a lot of terminal windows (at least three, up to 5 or 6).

If I am working in one of them, and switch to another app via the unity launcher (say the web browser), and then come back to the terminal windows by clicking on the terminal icon in the Unity launcher, the window that had focus and was raised is not raised anymore and may or may not still have focus.

This is really annoying as I have to dig under all the other terminal windows I do not want to finally find and click on the one I do want.

Is there a way that Unity can remember which terminal window had focus and was raised?

Update: thanks to everyone, but as far as I'm concerned this is a bug in Unity

When Firefox is set as my default browser, any links cliked in another application open a new blank Firefox window, not a new tab or a new window with the page I want.

Is that a problem with the configuration of firefox, of "Preferred Applications" or what else?

The firefox executable script works fine, because doing firefox http://example.com in a console window does the correct thing. Is there a way I can edit the "preferred applications" manually?

When I plug in my a second monitor on my laptop (sony vaio with Nvidia GT330M and proprietary driver) I have to log out and back in for the external screen to display something.

Is this really necessary? What are my other options? Why is the second screen not activated as soon as I plug it in?

Thanks!

When I open a RAM-intensive app (VirtualBox set at 2GB of RAM), some swap space is generally used, depending on what else I have open at the time.

However, when I quit that last application, the 2GB of RAM is freed up, but the same swap space use remains.

For example, right now, about two hours after having closed VirtualBox, I have 1.6GB free RAM and still 770MB in swap.

How can I tell Ubuntu to stop using that swap and to revert to using the RAM?

I just added a PPA repository for the development version of the GIMP, but I get this error:

$ apt-get update && apt-get upgrade
...
The following packages have been kept back:
  gimp gimp-data libgegl-0.0-0 libgimp2.0

Why and how can I solve it so that I can use the latest version instead of the one I have now?

I want to install a package (DigiKam), but it has a lot of dependencies. If I decide I no longer need this software and uninstall it, will the now unnessary dependencies be removed?

If not, how can I do it manually?

F-spot is great, but does not have video support. Picasa is arguably even better, but although mov support is possible, avi and mpeg support is unavailable.

Is there a photo management app that can also work with videos ?

Thanks
