Can Anyone Explain This In Plain English ?

CAN ANYONE EXPLAIN THIS IN PLAIN ENGLISH ?

I am trying to get Oracle SQLDeveloper to work on Ubuntu 14.10...

/usr/bin$ sqldeveloper

(gnome-terminal:7440): GLib-GIO-CRITICAL **: g_settings_get: the format string may not contain '&' (key 'monospace-font-name' from schema 'org.gnome.desktop.interface'). This call will probably stop working with a future version of glib.

Which Desktop Environment Do I Have: Gnome 2 Or MATE ?

Greetings,
I have been tinkering around with a distribution called gNewSense, a distribution endorsed and sponsored by the Free Software Foundation. I'm currently running version 3.1

I had a question about it.

I was wondering what the default desktop environment is. It looks to me like either Gnome 2 or the MATE desktop environment. I'm not sure which one it is. Both desktop environments look very similar to me.
A few places on the internet seem to indicate that it might actually be Gnome 2, however, I was under the impression that development for that version of the Gnome desktop has long ago stopped, and, in essence, the MATE desktop has taken it's place and continues to be developed for.

Thank you

Do I Have Two Versions Of LibreOffice Installed?

Hi everyone!

Having read about the latest LibreOffice version, I felt tempted to try it out. I uninstalled the default version on my Ubuntu machine and downloaded the .deb from the LibreOffice site and installed it. The new office has since worked without any trouble.

A few days later I decided to dump Unity and go back to Gnome. So I installed Ubuntu-Gnome-Desktop.

It was then that I noticed two versions of LibreOffice on the application dash (I think, because there are two sets of icons for each office application- see the attached screenshot).

Did Gnome install its own version of LibreOffice with it? Does it really have one? I don't know.

Whichever icon I use to launch the app, the office however always brings up the latest version. So, there's no problem in terms of application errors. As I thought there's no need to have an extra version of an app and eat up my space, I tried to uninstall through Aptitude, but it doesn't 'remove' LibreOffice.

Any advice, please! Thanks in advance.

Black Screen After Installing Gnome

Hi guys/gals.

I installed Debian Jessie with LXDE as my default desktop environment, no problems, except I can't play most games. So installed the Meta Package of the Gnome Desktop environment. Everything appeared to be ok, but when I went to reboot, all I get is a black screen.

I went to the Grub and typed in "nomodeset" to get me back to a desktop.
I uninstalled Gnome (not full removal), but still have the same problem.
When I restarted in safety mode, Gnome was still a desktop option that I could load, which I did. I'm confused. Do I need to do a complete removal?

I tried installing the nvidia graphic card driver as per the Debian manual, and that left me with only a root terminal and no GUI.

I've got about 2Gigs of ram and a 2.4 GHz Pentium 3 processor with an ASUS motherboard. (yes, it's a 12 year old computer, but not used for the past few years)

Any help would be great.

Thanks in advance,

Joe

Terminal Wont Load In Openbox On Arch

I've just installed Arch, and Installed and configured openbox and gnome terminal. Openbox starts, firefox works, but when I try to start gnome terminal, I curser spins for a moment and then it doesnt load.

I've tried to find a resolution to this but I'm not seeing much relevant to this specific scenerio. Also, this is my first time ever installing Arch, or any distro without a graphic installer or a kickstart script. My experience is pretty basic. I've used ubuntu/mint/centos for quite a while but figured this will be a good way to get me learning.

After I post this I am going to reboot to get back to command line and look at the installation and maybe install another terminal and see if this makes much a difference.

GPG-encryption - Explain It To Me Like I Am Five Please

I have read about GPG-encryption on the German, English and the Dutch wikipedia and I cannot make sense of it.

So can please someone explain the inner workings of GPG. And by that I don't mean how to make a key. The general idea of it.

Something like: there is Bob and John. Bob wants to send a mail to John in a safe way. He uses GPG for it. And then the story about public and private keys etc. As though I am five years old.

Wont Let Me Log In

Hello,

I installed Mint 17 xfce onto a friend's HP netbook a few months ago. Up until now all has been working pretty perfectly.

From this evening, she tells me that after she types in her password the following message appears:

no exec. line in this session file [her password appears here in plain text!] running the GNOME failsafe session instead

The only option at this point is seemingly to click ok. After that, this message appears:

Could not find the GNOME installation will try running the failsafe xterm session

Again the only option is to click ok, then this appears for a few seconds:

Cannot find xterm start a failsafe session

Then it goes to a black screen (though you can see the mouse cursor) on which it stays indefinitely.

She tells me that she wasn't trying to do anything other than web browsing and email checking before this started happening so there doesn't seem to be any logical reason behind it. Does anybody have any idea what is happening and how to fix it?

How To Cleanly Close A Graphic Display Manager Started Through Startx?

I just installed Gnome on Arch, and launched it with startx.

I wasn't able to figure out how to cleanly close the Gnome session even after searching for an answer online.

Ctrl Alt Backspace didn't work since it's usually disabled by default.

I had to log into another text terminal (Ctrl Alt F2) and issue sudo killall Xorg.

How can I cleanly close the graphic session and get back to my terminal?

What Is Xubuntu Besides Ubuntu?

I know it's xfce, but I also think it's debian. And I have it written down somewhere that it's GKT2. It's all kind of confusing: all these different terms. Gnome, QT, KDE. Hard to figure out what's what. Esp. when you're looking for apps. Like, 'This works best with Gnome and only marginally with KDE, but some have had luck running it partially on xfce.'
