Thank you, MOE-Lnx and Windozer, for your recommendations and also for your welcome.
I assumed that Light would be better for my hardware, but I wasn't sure if the software dependencies I need to pull down would change the equation. A couple of years ago, when I first considered running OOo on a light WM, I heard that I might as well run KDE anyway because OOo loaded most of its libraries. Now, I see that the OOo package installs as a single file. Has OOo become independent of the KDE libraries?
If you don't mind my asking another basic question about Light and Standard, my limited understanding of Linux suggests that the kernel handles memory management and the cpu queue. If that is correct, and if Light and Standard both use the same kernels, then is the Light version "light" (in terms of cpu and memory use) only because the packages installed by default are light? Or have changes been made also to memory and cpu management in Light as compared to Standard?
