i am willing to bet intalling all of these are the same process give or take a few changes, becuase they all appear as the same file type when i download them. recently, i downloaded a screensaver from kde eyecandy, and then i installed it, but it doesn't come up as an option in xscreensaver or in my normal choices for screensavers. i would very much appreciate some help, even learning how to compile these types of files from source code if its not too difficult

am i not being clear, or is the answer so obvios that people don't want to give me the time of day, still trying to work it out, any help would be appreciated

?????????????????????????????

It looks like you install the screensavers are installed the same way you install anything from source.

Then run the following commands
tar xzvf [file name] ( extracts the files to a new folder with the same name as the file, use z if it ends in gz, I saw a couple on there that are bz2, which you need to use j instead.)
switch to directory (cd [directory name], for future reference this will usually contain directions for how to install things, but the standard is what I describe)
./configure
make
make install (this step will need to be done as root)

By the way it's probably good to wait longer than two hours to bump threads. It will happen automatically after a day if there's not a response, since you responded that won't happen anymore.
