It runs swimmingly fast on my old dual-core machine.
No issues at all, except for the sleeping-mouse problem and the need-to-add-recommended-updates-to-the-repositories problem - both of which are well documented on the forum, complete with fixes.
I did wonder, though, why "unrar" was not pre-loaded together with Xarchiver by the installation?
(Maybe that's the case with all distros - my memory is not what it used to be!)
Also, does anyone have an IDIOTS GUIDE to LOLLYPOP?
