Yesterday, after I first installed Slackware 13.1 I had no trouble replacing the default wallpaper with a simple gradient. Very easy.

Today, (after re-formatting the drive and re-installing the entire system because I messed around with a script and it wouldn't boot) I can't change it.

I spent about an hour messing around with menus and settings trying to figure out how I did it, and eventually, as a last resort, turned to the help file.

It tells me to choose Configure Desktop from pop-up menu when right-click on the background. But Configure Desktop doesn't appear in the pop-up menu. (At least, not anymore it doesn't.)

The help file also says to use the Control Center, but I can't find any trace of that either.

I haven't the slightest idea why these are missing. Since I re-installed everything onto a freshly re-formatted drive, anything I played around with before shouldn't have any effect on the new installation.

The problem is there both when I login as root and user.

Anyone have any idea what might be going wrong, and how I can fix it? I really don't want to try re-installing everything again.

The only changes I've made to the system since the re-install is to edit /etc/inittab to replace the 3 in id:3:initdefault: with a 4, so I get a graphical login, and to edit /etc/rc.d/rc.inet1 to place an & at the end of the dhcpcd request which, according to the instructions I was following should put it in the background to speed up boot-time slightly.

I haven't (knowingly) played around with anything that should affect KDE, except changing settings from within the KDE menus.

I know it's probably going to be something very simple, and possibly obvious in retrospect, but I'm new to Linux and have no idea what I'm doing here.

Ugh. Ignore my previous post, I figured it out.

It's in "Desktop Activity Settings". Misleading name for it, and strange that the help file would tell me to look for "Configure Desktop".
