Hola compañeros! Aquí les dejo mi consulta.

Ayer mismo instalé la distro Ubuntu 14.04, desde 12.04.
Hice una instalación limpia del sistema en la partición que ya tenía creada. Desde USB.

El problema que tengo es que no puedo quitar los íconos que no quiero en el lanzador (no funciona "NO MANTENER EN LANZADOR") y tampoco puedo moverlos de lugar.

Ya probé con todo lo que encontré en la red:
reinstalé la distro,
reinicié Unity,
reinicié Compiz,
bajé los drivers de la placa gráfica (es una intel ingrada, al parecer está todo ok)

y el problema sigue.
Lo que más me molesta es no poder quitar los íconos que no quiero porque se me llena la barra y los íconos que sí quiero me quedan al final... un bajón.

Lo último que hice fue $ unity --replace
y me devolvió lo siguiente:

xxxxxxxxxxxx@xxxxxxxxxxxxx:~$ unity --replace

Evidentemente algún error hay, pero no se cómo hacer para corregirlo.

Agradezco desde ya toda la ayuda que me puedan bindar.
