After trying to get Lubuntu to dual boot over Windows 7 on my best computer, I decided to forget it. (Usually, this is quite easy but with this particular laptop it is not).
I’m going full bore Lubuntu and love the speed. My computer runs faster than it ever has. And check out the ram usage.
A whopping 391 megabytes at PC idle. Windows 7 took about 1 gigabyte. Windows 10 a lot more.
