Ubuntu :: Unity Launcher Doesn't Launch / What To Do?
Jun 19, 2011
I just upgraded to Natty this weekend, so don't have much experience with Unity yet. I tried to create a launcher, which starts an application on a VMware virtual machine using vmware-unity-helper (lot's of unity here .
Anyway, so I created the launcher, e.g. MS Project code...
The Exec command is just a little python script, which checks whether the VM is running and then executes the vmware-unity-helper command with the correct path and all.
The launcher works, when I double-click in in nautilus. But when I drag'n'drop to the unity bar and click it nothing happens. I pulses some (as if the application would start) but nothing happens.

The Compiz Setting page for Unity will not let me set the launcher to autohide or other hiding option, and the Experimental page will not let me reduce the icon size. The lack of hiding is another as the left edge of windows can disappear under the the Launcher.

I've upgraded to Ubuntu 11.04 some weeks ago and after some minor tweaking everything has been working fine. But all of a sudden, it seems after some package upgrades, I'm experiencing strange behavior: The first thing I noticed is that after reboot the default application that should be kept in the Unity Launcher have all disappeared. The unity launcher doesn't hide itself anymore. The unity launcher does not react to changes I make via the 'System Settings'->'compizConfig settings manager'->'Ubuntu unity plugin' menu (icon sizes in launcher, hiding method, etc.). Even after logout/login or reboot the changes aren't applied, although the corresponding settings in the configuration menus remain changed.
One application that used to work as a charm started giving the following error on startup: The program 'VESTA' received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 489 error_code 3 request_code 138 minor_code 4) Since yesterday everything was still working properly and today I get this strange behavior, it seems that something must have changed in between. The only changes on the system in the last 24 hours are the upgrades of the following packages:

For some reason the general launcher button (+ in circle) in the unity menu has disappeared. I do not know how to restore it. Which means I have great problems to start al apps that are not standard in the menu.

Just moved to Ubuntu 11.04 with unity and only have one problem...For most of my desktop needs I prefer to have the Unity Launcher up all the time (fullscreen apps don't cover it), and have set this option with ccsm.
However, when I watch mythtv, it is also under the launcher (and the top panel as well). How can I force mythtv to cover the launcher?
What I really need is a keyboard shortcut to hide the launcher, but the only shortcut is for "show launcher". (I guess the devs assumed everyone would want it hidden by default).
This, by the way is not my usual way for viewing mythtv. I have a projector attached to the desktop PC and it doesn't get a Unity Launcher by default (in Twinview), so no probs. However, occasionally I want to watch something on my computer screen, and that is when this issue arises.

How do you access preferences for changing size of the launcher bar or icon size, etc? I looked through system settings and could not find it.

I've installed ubuntu netbook remix on my Asus Eee Pc. I've fixed the wireless and various issues on it. This morning when I rebooted my computer the netbook launcher failed to launch and there were no icons on the menu. When I clicked on the go home applet it appears inactive and the windows are not minimized. When I typed netbook-launcher in terminal it gave a single line output named segmentation fault. I dont want to reinstall ubuntu.

I run 10.10, netbook. Fine so far. I don't manage to call an application that I added manually, though. I have created a menu item, with all subdetails, a proper command, icon, everything. And I can see it in the menu editor, and it is there, even after a reboot. But: How to launch it?? It never shows up under applications, it doesn't show up in Searches, I can't type it in. It does work fine, though, when I open a terminal and add the proper command. It then also shows in the launcher list (left column). But it can't make it 'stick' there, the right-click option does not show in this case.
how to *start* an application that I have added to the menu? Why would a menu item never show as an available application?

After upgrading to Natty from Maverick I started playing with the Compiz settings (trying to get my cube back), causing the Launcher to vanish!
This means I can't launch any applications - is there an easy way to restore it?

I have done a clean install of Lucid netbook remix on a Dell mini-12 laptop.
Finally managed to get the broadcom wireless driver packages and poulsbo drivers to install correctly and decided to install all the offered updates.
After reboot I get the menu bar at the top but then desktop flashes between white and my background image for ages but does not give me the normal netbook tabs etc.
If I try a restart I get a pop-up saying 'Netbook Launcher is not responding'.

I made a shell script to launch dr. java that works fine, but when I try to make it a launcher, it does nothing. This is the script:
Code:
#!/bin/bash
java -jar drjava-stable-20100913-r5287.jar;
Why is the launcher being difficult?

When Ubuntu 11.04 beta appeared I've read an article describing the way to move Unity Launcher to the bottom of the screen by editing some config files. Now I've upgraded to 11.04 and can't find the article anywhere.

Recently upgraded to 11.04, and I am happy with the intent but unhappy with the bugs.
I have a specific problem at the moment, the unity launcher will not auto-hide, which means I cannot access the left side of any application (such as the back button for instance). Does anyone know of a fix?
A restart fixes the problem, but If I don't want to do that then I have to set the auto-hide option in Compiz to never, so that application windows stop at the launcher, and don't dissapear underneath. (setting back to other auto-hide options doesn't work)

I've just installed Ubuntu 11.04 and have come across a strange bug, where after using Ubuntu for a while, the launcher suddenly appears and will not hide. This occurs when my mouse is no where near the launcher. I have a duel screen display.
This is very annoying as the launcher appears above the windows I am working on as shown in the screenshot:

I have tried changing the launcher hide options in ccsm but it doesn't seem to make any difference. At the moment it is set to autohide.

When Ubuntu one is syncing there is no progress bar in the Unity launcher as there is supposed to be. What could be wrong?

I upgraded to 11.04. A launcher I had created before the upgrade shows up in the dock and works nicely... but I want to change what it does.
[URL]
says to edit the .desktop file. Fine, but there ought to be a way to do it with the gui, shouldn't there?
[URL]
suggests, after reading between the lines, that you can only edit launchers in the gui when they're not in the dock; the dock is only for pinning launchers that exist elsewhere.
But I don't know where my launcher file is, it's certainly not on the desktop, since I removed it from there before upgrading.
I see that in the new world, deleting a launcher from the desktop removes it from the dock, too.
I am very sad that I can't have launchers on the dock without having them on the desktop, and that there's no way to edit launchers from the dock.
I am aware of the "switch back to classic and stop using unity" workaround.

I love this unity launcher panel on the left. but i think it's taking too much valuable space on my small screen so i set up a super small app dock with everything i use but i can't seem to completely hide this unity launcher the only options i find in CCSM are "always show" "autohide" and two other things i can't seem to understand; anw i haven't found a "Always hide". is there a way to do that ?

I installed Natty Narwhal on a brand new Ideapad Z570 and everything worked out of the box except wifi for which I had to blacklist acer_wmi.
I installed Google Chrome and replaced firefox with chrome in the launcher. So everything works fine until I reboot. Firefox is back. I saw this a couple of times so I though why not just get rid of firefox. Unfortunately now there's nothing in place of firefox.
I tried unity --reset but that just shows a bunch of errors. I have dconf-tools and libdconf0 installed.

I was just wondering how I could reorder/drag n drop/move the unity-2d (qt version) icons in ubuntu 10.10, like you would in the mutter version unity. I can move the launcher up and down, I just can't pull them off the launcher and drag them around. Is this a bug or has it just not been implemented yet? Other than this, I love unity 2d and can't wait for the compiz-based unity 3D to use in 11.04

I've just installed the new Ubuntu 11.04 and encountered a strange problem. The Launcher bar appears, everything is ok, but i can see no icon on the Unity Launcher. When i move the mouse over the launcher, it tells me where the icons should be. The apps also open when I click in those places. But NO icon? Can anybody tell me why is this happening? It is very annoying. I would accept it easier if it didn't work at all.. but not this way.

I recently installed 11.04 and Unity 2D (because my old laptop can't run the full 3D version). So far I'm pretty impressed and its growing on me, despite the negative press I'd heard and my own skepticism of change going into the new UI.
One thing that I haven't been able find out is if there is an option to vertically resize the launcher based on the number of active icons. I only have about half a dozen icons pinned to the launcher permanently, so there's a lot of blank "dead space" on the bottom half of the launcher unless I have a zillion other things open simultaneously.
Is there a way to make the Unity 2D launcher automatically shrink upwards to fit the number of pinned icons + active applications? (I've attached a mock up of the sort of feature I'm talking about.) It would be fantastic if there was a way to do this because it would be a much cleaner and more efficient use of my screen space. I've already downloaded the Unity 2D Settings application, but there are only 5 or so things you can edit with that little app. I was hoping for a method with a bit more flexibility.
I've heard that Unity 2D is specifically designed NOT to use Compiz, so things like cube desktop and wobbly windows will never be available in this 2D desktop environment. (Sadface for losing out on the eye candy I used to have in 10.10 )

I've just upgraded to ubuntu 11.04. After I login with unity, I can only see my background and desktop items. There is some space on the left side and on the top on my desktop. I clicked on those space and I found that there is some button on it. It means that the panel and launcher are completely transparent. I entered "/usr/lib/nux/unity_support_test -p" in terminal. It told me that my computer meet the requirement to run unity. Also, my computer work fine without unity(classic ubuntu session). I really don't know what's wrong.

Now is hard to understand which app is running and which's not, even I make it "backlight toggles" in CCSM, I have to looking at it for several seconds or find small triangles.
Can I make it just like windows7, let it only appears when app is running?

Do not know yet if unity is something for me, but I will find out .I tried to change the keyboard shortcut for the launcher (default Alt-F2).I did this by changing it in ccsm, under "unity plugin"-"Key to execute a command".

I'm running ubuntu 11.04. from time to time, the unity launcher gets stuck in an open position, preventing me from clicking anything on the left side of the screen. this is terribly annoying. is there a *simple* way to change the properties of the icons in the launcher? I have there some custom application launchers that were automatically imported to the launcher during upgrade (they were in the top menu).

htop is my preferred system monitor, but I have a problem with it in Unity: When I open htop from the Applications lens there's no entry in the launcher added for it. This means I can't add it permanently to the launcher. It may have to do with it being a terminal based program, but I was wondering if there is a way to get it permanently added to the launcher?

I think 32 pixels is still very big for a launcher, can I shrink them more somehow in Unity? I'm talking about Ubuntu 11.04, of course.

I switched on my machine this evening and the first thing I noticed was the home icon in the unity launcher has changed, then I noted then I noted that the window switcher icon, power-off icon and me icon in top right are also different.
On starting nautilus (clicking on home icon) it looks more like thunar (although about says its not). A screen shot showing "nautilus-thunar" and the desktop is attached.
Firefox's minimize, maximize and close icons have also changed - see other screen shot.
Anyone got any idea what's going on? Anyone else have this.
