My dad was experiencing some problems with an ageing LXLE Linux distro. It was becoming mysteriously slower. I did a full upgrade, but still no joy. So then I downloaded the latest version of LXLE, installed it, and updated the sytem. Unfortunately, there seems to be a bug in either the screen saver or power manager, as the screen becomes blocky after leaving the machine for awhile.
I could not handily locate the settings. Seeings I had a spare copy of Windows 7 professional, I decided to install that instead. So far, so good.
LXLE is based off of Ubuntu Stable. Unfortunately, I think that there is a distinct lack of quality control with many so-called stable distributions.
It’s undoubtedly about this time that Linux advocates offer their “why don’t you try” lines. My short response is: no. The longer answer is: trust me, I am an expert Linux user, and the answer is still “no”. Debian Stable is too old for me, Ubuntu’s usability is not quite what I want, Fedora is highly crash-prone, and so on, and so forth.
