Lubuntu is advertised as lightweight and good for older hardware. The Dell is circa 2005.

I installed Ubuntu and the UI response seems to be very slow. I am tempted to try Lubuntu, but before I do, I wanted to ask if I should expect the same or a snappy response?

Bonus if you have installed both on your system and can compare the two. Trifecta if you have the XPS 400 running either Ubuntu and can comment

    "Ubuntu 16.04 recommends 512MB (help.ubuntu.com/lts/installation-guide/s390x/ch03s04.html)." This is crazy. Ubuntu 16.04 uses over 1GB RAM when idle on my ThinkPad, and I've even disabled a number of default applications like Evolution. – Alcuin Arundel Jun 27 '16 at 1:47

    There are two issues with that minimum requirement. 1: it's old, and 2: it's for Ubuntu Server, which has no GUI at all. – TheWanderer Jun 27 '16 at 2:00
  • If you're really looking for lightning speed, look to Lubuntu or Xubuntu for Ubuntu variants, and then take a look at Puppy or one of CrunchBang's successors for other distributions. – nixpower Jun 27 '16 at 2:07
  • There is no shadow of a doubt here: Lubuntu is the lightest of all Ubuntu flavors, because lxde is the lightest desktop environment used by official Ubuntus. – ipse lute Jun 27 '16 at 7:47
  • The Dell machine had a mere 512MB of RAM so Ubuntu was not usuable. On the other hand lubuntu was usable. An upgrade to 2GB is in the near future. – gatorback Jun 28 '16 at 4:50

Lubuntu will almost certainly perform better. My brother had an old 512MB Dell desktop that I brought back to life. I first tried vanilla Ubuntu but it lagged horribly, then tried Lubuntu and it ran like it was brand new.


I have both Ubuntu and Lubuntu 16.04 on my older HP Pavilion desktop with 1 GByte RAM. Ubuntu will bog down and run slow. Lubuntu is more responsive. The good thing is that they run the same software except for the desktop environment: Unity versus LXLE. I don't feel I've lost anything by running Lubuntu.
