I have install Ubuntu 14.04 LTS in an ARM device, but it comes without a Graphic User Interface. In another ARM device I managed to install a GUI (Ubuntu Desktop), but this device has less internal memory and can not be installed. So I have been looking for other alternatives such as LXDE, Enlightenment or Icewm. However in tutorials I have been looking for seems that the repositories needed are outdated.
For example while installing Enlightenment I get this error:
package enlightenment has not installation candidate
Then, when the installation of Icewn goes good, but when I try to lunch Icewm with sudo icewm I get this error:
$ sudo icewm
IceWM: using /home/ubuntu/.icewm for private configuration files
IceWM: Can't open display: <none>. X must be running and $DISPLAY set.
I don“t know why, my ARM device is connected to a VGA display.
