Launcher Ubuntu V15 Not Found

I have downloaded an attachment from a website and an icon has now appeared on the bottom panel of my debian distro with gnome shell (classic).
This icon will not go away even with reboot.
If I right-click on the icon it offers me 'launch' and 'properties' option. But there is no 'delete' option.

If I click on the icon it will take me back to the same website and open the attachment again.
Now it's forever on the bottom panel of my desktop.
Clearly this is a bug.
Can someone please advise how I can get rid of this? Thank you in advance.

I am new in java. I executed a java program using eclipse. the program contain two java file. when i try to run it using terminal in Ubuntu.

I've downloaded the latest eclipse (.tar.gz) and unpacked it to /usr/bin and created a launcher for it, but it doesn't launch.
I also created a shell script on the desktop called eclipse.sh, content :
cd /usr/bin/eclipse
./eclipse

and did a chmod 755 /Desktop/eclipse.sh in a terminal as root.
I did a chmod 775 on the eclipse executable as well, but it still won't launch

NB I followed the same procedure with Bluegriffon and that runs OK.

I bet I'm missing something obvious, but just can't think what.

Box is AMD Phenom ll x4 / 8GB DDR3 running Mint 17.1 LXDE.

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.

An answer was posted for linuxmint 11 but,in mint 17 the advanced option does not exist in accessories menu. It also is not in apps/nautilus/desktop via gconf-editor all options are checked here but still no trashcan?
Right click does show "Move to Trash" option but I want trashcan icon on desktop for simple drag and drop. It was around in Linux mint 17 but not in 17.1?

Hey just signed up after lurking for a bit.

I'm using Mint 17.1 and following the advice in this post to solve my missing menu problem which worked fine.

But now after using Code:

mv ~/.config ~/.config.org

my FPS in a steam game went down from 70 to 30.

I did some re-installations in my package manager, but the FPS still sucks.

hi,

I installed Zorin 9 on an older laptop normaly running Windows® XP.
After the installation i see the backgroud but no icon's or bars.
Clickin the right-mouse button gives me some menu's like it supose to do.
Reinstalling gives an error no diskspace.
My questions:
How can i get the dsktop screen to work? How to format before installingZorin 9?
Please help because I HATE WINDOWS®

Ive been reading comments for the past four weeks on ubuntu and mint. cinnimon desktop or unity desktop. theres all sorts of stuff being said. after trying both of them out myself 'AS A NEW COMER' I can say that if you have been brought up on macs do not go near mint cinnimon because it operates and looks just like windows. For a mac guy like me, windows makes absolutely no sense. I cant stand it. the unity desktop is much more mac intuitive. of course its different, its linux, but it is more intuitive to a mac guy. If you have been brought up on windows then you MUST use mint cinnimon because it will be a delight for you.

I love Ubuntu and the unity desktop because I'm an old mac guy!

Hello Linux users. I'm described as a newbie (which i am) but you've never seen a newbie as new as I am I'll wager.

I installed Zorin 9 OS core as an alternative to Microsoft crap that I'm really tired of, (cost as well as never vending bugs). Yes I know I'll still have bugs with linux but at least the patches and fixes in any Linux distro is for the benefit of Linux users and not to sell more Microsoft crap.

I have evidently been reasonably successful to install the latest Zorin 9 with my desktop environment choice. However I'm used to (and like) the MS so called quick launch bar at the bottom of the XP desktop installation, from which I can place links of any app or web link to instantly go there. Correct me if I'm wrong but Linux has basically the same quick launch function which I can choose from the software center and I've tried to select and install at least 2 named Cairo-dock and Docky for example. I did choose and install those according to the Linux prompts but I notice no change in the "Avant Window Navigator" at the bottom of my desktop, and when i try to drag a web link or app to that bar it either flips back to the link spot i saved on the desktop, or there's no action at all. In other words I am not able to put a link or app on the AWN, which AWN does not serve as a dock launcher at all (except for my Firefox browser icon WHICH IS INSTALLED at the left bar location and does work to quick launch Firefox when I left click on it.

So how do I not only properly install that notorious quck launch app in linux Zorin 9 OS and finally drag or otherwise install my links there?

thanks for any advice or replies.
