How to remove a launcher from a Gnome Panel?


I'm having trouble removing icons from GNOME's launcher.

Tried to get used to UNITY, but no luck with it. I want to go back using GNOME (2/fallback session).

I would like to have quick launch buttons to run apps - so decided to place them in launcher (top bar), either on left or right side.

The problem arrives when I want to remove them (or some of them). When placing them in Trash, as this is the only way I've found to removing them (trying to at least) it shows a dialog message:

"cannot move file to trash, do you want to delete it immediately?"
"the file .... cannot be moved to trash"

So I click on "delete", but still cant place it in trash.

"unable to trash file: permission denied"

Even tried to look in terminal under:

but nothing there to delete ...

What's going on?
How to remove those app icons?

Finally, with the help of wonder (IRC nickname) on I found the cause of this problem and ultimately fixed it.

The quick and dirty fix for this issue is the following:

edit ~/.local/share/applications/mimeapps.list and find line that starts with:


in my case the line looked like this:

Note there was no nautilus-folder-handler.desktop file in my system at all, and that is perhaps exactly why kde4-kfmclient_dir.desktop next in the list was tried. I know it doesn't make much sense, since kde4-kfmclient_dir.desktop doesn't exist either but...

change it to


Save the file. Check your Places-> ... Now it should work as expected, that is run Nautilus.

This is a really quick and...

I recently upgraded to Ubuntu Netbook Edition 10.04 Lucid Lynx (previously Ubuntu Netbook Remix) on my netbook and noticed the Gnome Panel was locked. I didn't search for a work-around because I've been very busy these days but


found a "fix" for this (many thanks!) so I decided to share it with WebUpd8's readers - if you own a netbook with UNE 10.04, you will definitely find this useful.

Ubuntu Netbook Edition (UNE) 10.04 comes with a locked Gnome panel and a few other Gnome settings

. The reason for this is that the users can switch between the Ubuntu Netbook Edition interface and the normal Gnome interface cleanly.

But there's a problem: you cannot change any Gnome panel settings or add / remove applets

- which I find it very annoying since you cannot install applets which make Ubuntu Netbook Edition a lot more usable such as

DockBarX, Namebar


Gnome Global Menu

and so on.

Here is a work-around which will allow you to add or...

When I right click the Filezilla icon, the only options are "launch" and "properties". How do I remove it from the top panel?

You are using the Gnome-Classic interface - either you are using this by choice, or you are using the fallback mode which occurs if your graphics card & driver doesnt the 3D Acceleration required for the full Gnome-Shell GUI.

To add and remove application launchers in the gnome-panel you need to:

Press Win+Alt and right-click the top menu bar - N.B. Win is the Windows Symbol key

If you are not using Compiz then you need to :

Press Alt and right-click the top menu bar

Much more information is described in the linked Q&A and other links in that answer.

Like most GNOME applications, GNOME itself is highly configurable. You can configure GNOME's panel, its main menu, and its overall appearance and function. The following sections briefly show you how.

You can add a launcher to the GNOME panel. Clicking on a launcher launches a predetermined application. To add a new launcher applet, right click on the panel and select Add New Launcher from the pop-up menu. The Create Launcher Applet dialog box appears, as shown in Figure 6.10.

You can specify a name for the launcher, a comment, and the command that GNOME executes to launch the application. GNOME will automatically provide a default icon, but you can specify the icon of your choice by clicking the Icon button.

If an application is already on the main menu, you can quickly create a launcher for it. Simply right click on the application's menu item and select Add This Launcher To Panel from the pop-up menu.

If your panel...

Ubuntu 11.04 Natty Narwhal replaces the familiar Windows-like Gnome desktop environment with the


desktop environment. Personally, I found the switch rather jarring at first. I think I may have even been angry. But after spending some time with Unity, I think I’m starting to get it–especially since I run Ubuntu on a netbook, which is Unity’s forte.

Anyway, I was most devastated when I lost my precious panel launchers. Similar to the Windows Quick Launch Bar, Gnome let you launch frequently used applications and documents from convenient icons along the top panel.With Unity, there is no such thing. Rather, all graphical shortcuts are confined to the vertical launcher bar, which runs the height of the left-hand side of the screen and auto-hides.

While the Gnome panel was comparable to the Windows taskbar, the Unity launcher is more like the OS X dock. Application icons pop up here when they are running, and you can choose to keep your favorites there...

A launcher is an object that performs a specific action when you open it.

You can find launchers in the panels, in the panel menubar, and on the desktop. A launcher is represented by an icon in all of these locations.

You can modify the properties of a launcher. For example, the properties of a launcher include the name of the launcher, the icon that represents the launcher, and how the launcher runs. For more on this, see the section called “Modifying a Launcher”.

You can add a launcher to a panel in one of the following ways:

From the panel popup menu

Right-click on any vacant space on the panel, then choose . The Add to Panel dialog opens.

To create a new launcher, select Custom Application Launcher from the list. A Create Launcher dialog is displayed. For more information on the properties in this dialog, see the section called “Launcher Properties”.

Alternatively, to add an existing launcher to the panel, select Application...

I've shown previously how to add an item to Ubuntu's (or any Gnome desktop) menu, but that post only showed how to edit the menu for a single user. In this post I'll show how to add an item to the menu so it shows up for every user on the system. I'm going to add a special icon to launch a terminal window from the Applications->Accessories menu in Ubuntu. You can find more info at the GNOME Documentation Library.

Create a Desktop Launcher

Right click on the Desktop and select Create Launcher. Enter a name, I'll call mine Tux Term. Enter the command, in my case it's gnome-terminal.

Click OK. You'll now have an icon for Tux Term on your desktop.

Edit the Launcher File

You need to add a line to the launcher file that you just created. Double click on your new icon to launch a terminal for the next step.

cd ~/Desktop
gedit "Tux Term.desktop"

Add the following line to the end of the file and save it.

Date: Fri, 07 May 2004 14:44:14 +0000 I need to change the action of several of the buttons on the gnome panel for all users. Since the name that each launcher gets in $HOME/.gnome2/panel2.d/default/launchers isn't the same for all users, I don't think I can just do a global find/replace.

Ubuntu 17.10 uses Wayland in the default session and Xorg for optional. However, many graphical applications need to run as root so far does not launch in Wayland.

You’ll get following similar errors while running graphical applications via root:

For some applications, e.g., Synaptic Package Manager, Grub Customizer, Gparted, and Ubuntu Tweak, they does not launch in Wayland.

Or you may get following error when trying to launch them via gksu command:

Failed to run *** as user root. Unable to copy the user’s Xauthorization file.

Starting graphical application via sudo in terminal window will get error:

No protocol specified. Gtk-WARNING **: Cannot open display: :0

The most straightforward workaround is to use xhost to temporarily allow the root user to access the local user’s X session.

To do so, run command:

xhost si:localuser:root

After running the command, these graphical applications can be launched...
