Okay, so I installed the Gnome Slackbuild GDE (
http://gnomeslackbuild.org) and IMHO, it's still pretty buggy. For one thing, their package manager didn't install at all. Secondly, a number of apps or applets crash even after I've enabled avahi and done the other configuration tasks they speak of including the applet that lets one set nautilus preferences. Thirdly, the base install didn't include any of the system/administrative stuff although it did successfully include seemingly all of the system/preferences apps. Fourth, it only installed one visible, usable gnome panel (the top one) and that had absolutely nothing on it at all although of course I was able to add a menu, task switcher, clock, and so on manually. I'm sure it is a work-in-progress but it seems to me that it isn't quite ready for prime-time yet.
The good news is that at least it seems *not* to have screwed up xfce4, which I'm liking *very* much indeed the more I use it. Since it "updated" several of the default slack libraries, I was afraid that it might have.
Now, if I could only find a decent twitter client.
Slackbuilds does have qwit for KDE and I installed that, but although it seems to load the various time-lines fine, absolutely nothing actually appears which one can see--text, images, nada. I tried a couple of those which use adobeAIR, but none of those will install.
I do like the version of grub which slackware has, though. Unlike previous versions I'm familiar with, with this one one has only to change the /boot/grub/menu.lst to reflect system changes and be done with it. There is nothing else to run, no further updating to do. It's so much better than the ancient one in debian lenny that I've installed it to my mbr and am now using it to boot both operating systems.
