GNOME Desktop

Since the default firmware of Neardi Ubuntu 20.04 is LXDE, GNOME needs to be installed afterwards.

The GNOME desktop is a graphical user interface based on free software that can run on Unix or Unix-like operating systems such as Linux, Solaris, BSD, etc. The GNOME desktop provides a friendly, easy-to-use, customizable desktop environment, as well as a series of standard desktop tools and applications.

Operating Environment:

  • LKD3588/LPA3588/LPB3588

  • Ubuntu 20.04 LXDE desktop

Other Neardi models can refer to this, but have not been practically verified.
