I have an old netbook, a Samsung NF110 that is hopelessly underpowered now with only 1Gb RAM and a 1.66GHz Atom CPU. It used to run Windows 7 (can you imagine?!) and was ok for basic word processing when I got the thing and had a really good battery life. I installed Ubuntu on this a while ago and found it very slow. I recently put Ubuntu 18.04 on, simply because I use this on the desktop. Yesterday I wanted to see if it could provide another screen and run pskreporter and it sat there for 10 minutes allegedly loading Firefox. Hmmm. I remembered at that point that I had planned to put it on eBay anyway but wondered why on earth it was just so slow with Linux.
Enter Lubuntu. Lubuntu 12.10 has given the poor little thing a new lease on life. It is actually usable and no Gnome awkwardness. I’d still rather it had a little more RAM (like, I dunno, 8 times as much!) but it always was a handy little PC so it can remain in the shack now.
And on Lubuntu – well sort of – I installed LXDE on the shack PC as Gnome continues to annoy. So far, so good, and of course it’s easy to switch between desktop environments.
