Thanks for the post.
Have been using some form of Linux since 1994-1995.
Started with UMSDOS version of slackware.
Migrated to Mandrake and used Redhat for a number of years. But I became unhappy with the software bloat under Gnome & Unity. Then I discovered XFCE and applied that on RedHat 8.0
WOW what a difference.
My last install was Xubuntu, which has XFCE as the native Window Manager. I like it, but am always interested in something better. I got caught in an upgrade problem and will in the future re-install the OS on this computer. Do you have any advice for an improved OS that uses a light Window Manager like XFCE?
With your stated experience, it should be no problem for you.
I still have a RedHat CD from around 2000 (or so) buried somewhere.. I should stick it in and see how it performs on my system now :)
BTW, have you tried out Mint XfCE? It may be what you are looking for...
