Lubuntu and Xubuntu

The lightweight flavors of Ubuntu using LXDE (Lubuntu) or XFCE (Xubuntu).

The following are minimum requirements for Xubuntu:

  • 512 MiB of system memory (RAM)
  • 7.5 GB of disk space
  • Graphics card and monitor capable of 800x600 resolution
  • CPU: PAE-capable

Recommended for Xubuntu 18.04 64-bit or later:

  • 1~2+ GiB of system memory (RAM)
  • 8~16+ GB of disk space
  • Graphics card and monitor capable of 1024x768 resolution
  • Dual Core processor

Lubuntu can run with even less:

Lubuntu Minimum requirements:

  • CPU: PAE Support, Pentium 4 or Pentium M or AMD K8
  • 256MB - 384MB of RAM

Lubuntu Recommended requirements:

  • 1 GB RAM

 

Kubuntu

The official flavour of Ubuntu using KDE. The default desktop environment is KDE Plasma Desktop.

Minimum

  • Xenial Xerus (16.04)

    • 5 GB of free disk space
    • other requirements are similar to the following
  • Bionic Beaver (18.04)

    • 1 GHz processor
    • 512 MB of system memory (RAM)
    • 8 GB of free disk space
    • VGA capable of 1024x768 screen resolution

The minimum requirements were last mentioned in Kubuntu 8.04 news announcement, then merely copied from Ubuntu 12.04 release note and has since deprecated, and not found at elsewhere. The minimum requirements for newer release is unofficial and subject to testing on real hardware or in a virtual machine (VM). Kubuntu has varying requirements on VM.

Xenial Xerus (16.04) on VM: Requires at least 1 GB RAM, 10 GB fixed-size Virtual Disk Image, 128 MB video memory. Selecting "Try Kubuntu" or "Install Kubuntu" does not matter. Live session will takes time to load; If virtual machine has stopped responding, do reset and start again. Installation may take longer time. User will see "low disk space warning" during installation but will succeed.

Bionic Beaver (18.04) on VM: Requires VT-x/AMD-V hardware acceleration, regardless of 32-bit or 64-bit ISO image. Requires at least 9 GB fixed-size Virtual Disk Image. With 512 MB RAM, choose either "Try Kubuntu" or "Install Kubuntu"; otherwise, running the installer from desktop will not work as expected. With 768 MB RAM, user can first choose "Try Kubuntu" and later can also run the installer from the live desktop.

Recommended

  • 1 GHz dual core processor or better
  • 2 GB of system memory (RAM)
  • 10 GB of free disk space (the more hard disk capacity, the better)
  • VGA capable of 1024x768 screen resolution. If desktop effects are desired, a supported GPU is required.

 

Ubuntu Mate

Ubuntu Mate is a official flavour of Ubuntu, based on Mate DE. Designed to run on modern desktops and laptops, micro computers and older hardware alike.

Ubuntu Desktop

The main flavour of Ubuntu using Unity (16.04) or GNOME Shell (17.10 and newer).

Minimum

  • Xenial Xerus (16.04)

    • 700 MHz processor (Intel Celeron or better)
    • 384 MB of system memory (RAM) for 32-bit
    • 512 MB of system memory (RAM) for 64-bit
    • 8 GB of free disk space
    • VGA capable of 1024x768 screen resolution
    • Either a DVD drive or a USB port for the installer media
  • Bionic Beaver (18.04)

    • at least 1 GHz 64-bit processor, given that 32-bit desktop live was discontinued
    • at least 1 GB of system memory
    • at least 9 GB of free disk space
    • other requirements may follow the "Recommended" section

The minimum requirements were last mentioned in 12.04 release note, and has since not found in release note of newer releases. The minimum requirements for newer releases are unofficial and subject to testing on real hardware or in a virtual machine (VM). Ubuntu has varying requirements on VM.

Bionic Beaver (18.04) on VM: Requires VT-x/AMD-V hardware acceleration. Requires at least 1156 MB RAM and 128 MB video memory, but disable 3D acceleration for at least usable desktop to open menu and change settings. This is the practical minimum for a test drive, but not for daily use.
