I must admit to being curious. I've belonged to a number of Linux forums over the last few years, and the one over-riding feature that I've noticed (as well as on many how-to websites) is that almost everything is written for Ubuntu, or its derivatives.
Doesn't anybody use systems that are not 'buntu-based? I started off with it a couple of years ago, when XP went EOL; but within just a few months, my 'big rig' (a 2004 Compaq Presario desktop.....genuine Compaq, not an HP 'namesake'; therefore very good quality) started freezing up at the slightest provocation, and the screen would always go black, or freeze into interesting multi-coloured patterns; largely due to the 3D requirements of the Unity desktop. I tried some of the lighter versions, and the graphics problems remained.
So I switched to Puppy Linux.....and the hardware problems quit, just like that.
Unfortunately, Mark Shuttleworth has decided he wants to be the Bill Gates of the Linux world, and Canonical is steadily dropping support for older hardware.....the one thing that has always been the mainstay of the Linux 'ethos'.
What are other people's thoughts on this?
