At the very beginning of the booting of an installation media (typically a USB stick), before even choosing your language, there is an intriguing symbol. It represents a keyboard, an equal sign (=) and a circled human. This circled human is similar to the accessibility symbol in GNOME.
What does the symbol mean and what would happen if I press a key at that time?
I just upgraded from Ubuntu 12.04 to Ubuntu 12.10. In the process, a new folder appeared in my home directory called fontconfig. It includes some 24 files with a .cache-3 extension. This happened on all my computers.
What is this folder? Can I safely delete it?
I installed Ubuntu by choosing the option "Something else" at the step called "Allocate drive space" of the installer. Then I created my own partition table.
Now that Ubuntu is installed, can I check whether I am using LVM for my volumes ? In particular, can I see it in GParted Partition Editor ?
I have purchased a lot of content in the Ubuntu Software Center (apps and magazines) and I also have purchased music in the Ubuntu One Music Store. I have a few related questions about the transmission of this content to another person.
Do I have the legal right to transmit this content to other people ? To my family ? To my heirs ? To my close friends ? To remote acquaintances ?
When I do transmit such content, should I delete it from my own devices ? Or can I copy it ?
Do I have the right to sell it over ?
If I indeed have the right to transmit content, how should I do it ? For instance, should I transmit my Single Sign On email address and password ?
If some of those questions should be asked separately, please tell me in the comments and I will post them as new questions.
I have an image called ZEAKR.jpg. How can I know its size and format from the command line?
I am creating an application for the Ubuntu App Showdown in Python + Gtk with quickly. I am calling it Discvur. I would have liked to include some keyboard shortcuts.
Searching the web, I found this page about AccelGroup and this page about gtk_widget_add_accelerator but I don't understand how to start with it. Could you tell me how I would define an appropriate signal and then use it in my application?
I have already acquired a S/MIME certificate (a .p12 file) issued by an authority. Using it in Writer, I can digitally sign documents by following this procedure : How do I make a digital certificate available to LibreOffice Writer for digital signatures?
Can I do the same for PDF files? If yes, what method do you suggest me? I would prefer a solution that relies on Free Software.
I am the lucky owner of a pivot monitor, which screen can be rotated (physically). What is the easiest way to make my display turn when I turn my monitor?
For the moment I first launch the 'Displays' app, and then change the settings and confirm. But this is in fact quite a laboured procedure, since I want to switch my orientation up to a few times per minute.
So is there an indicator for this, or equivalent? Can I set a keyboard shortcut that would launch a dedicated command? In fact I am thinking of something similar to the Windows program iRotate.
I sometimes see the expression of Vanilla Ubuntu but I cannot find what it means.
What kind of version of Ubuntu is Vanilla Ubuntu?
My computer is connected to the Internet through a wifi-router. I want to have access to my computer remotely, for example using ssh. When I ask my computer what my IP address is, for example by going in the network indicator, I get 192.168.1.101. But when I go on a website as whatismyip.com, I get a totally different address, probably the one of my router.
So what address should I use to access my own computer remotely and not any other machine in my home wifi-network?
I want to make free space on my computer, and Baobab tells me /tmp is 8 Gio large.
Can I delete all the files in /tmp safely? Do I have to close some programs first?
Additionally, why is this directory so big? Though my /etc/defautl/rcS indicates TMPTIME=0?
I am now running Ubuntu 11.04, but I remember that in previous versions of Ubuntu you had an interesting functionality in the clock indicator. You could see how late it was in some places in the world different from your current one. This was associated with a world map showing where it was day and where it was not.
How can I get this functionality back in the clock indicator ? Otherwise, do you advice me another solution to know easily how late it is in some special places ?
What is the way to be able to type Japanese characters? Could someone make a how-to in order to explain the few steps to get it?
It seems I am running this bug. Sometimes my clock applet just stops running, and I have a pop-up window saying 'The clock has quit unexpectedly'. Between 'Reload' and 'Close', I have unfortunately chosen the second option. Even if I have rebooted, I cannot launch the applet anymore. I am on Ubuntu 10.10.
Can somebody give me the command line that I could use in the application launcher appearing when Alt + F2 are hit ? Or any other solution in order to recover the applet on the gnome-panel ?
What is so new about indicators?
What did we have before?
Are there technical or usability differences?
Why is (was) there so much fuss about it?
Why is it under the 'Canonical Partners' section in the Software Center?
Should I install it?
I would have liked to buy some software, but the 'For Purchase' category in the Software Center remains desperately empty.
How do I activate the availability of such apps?
Is it possible that I am unable to connect to Ubuntu One because of my proxy ?
When I create a new document aimed at containing only plain text, I am not obliged by Ubuntu to add a .txt extension to its name. It works indeed very well: gedit opens it without problem, understanding very well that it is only text.
The only two pro arguments I have found from now on for adding an extension are 1/ interoperability with Windows systems and 2/ avoiding confusion with folders having the same name. Nevertheless those two arguments do not convince me at all. As a consequence, should I keep the reflex of adding an extension to files or not?
I sometimes want to use my computer as a DVD-player. Unfortunately I know that I will often have to cope with encrypted DVDs, for example with CSS.
Therefore I installed the libdvdcss2 library from Medibuntu. But from now on, how can I be sure I will be able to read any DVD whatever its encryption, may it be CSS or another protection?
By the way, I precise that passing through such protective measures is allowed in my country, "for interoperability purposes".
I added some extra repositories with the Software Sources program. But when I reload the package database, I get an error like the following:
W: GPG error: http://ppa.launchpad.net trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8BAF9A6F
I know I can fix it using apt-key in a terminal, according to the official Ubuntu documentation. But I would have liked to do it graphically. Is there a way to do this without using a terminal?
