I have now installed linux on my sony vaio pcg-c1x

the hard drive had to be removed(READ: the computer had to be completely disassembled). it was then used in another computer and linux was installed, then put back into the sony.

I now have two problems tho:

1) the standard RedHat desktop comes up with an error like: "applicatoin 'gnome-panel' has crashed due to a fatal error". Any ideas?

2) When i tried to install linux RPM it said i needed j2re (which i have), and libXss.so.1. What is libXss and where do i get it? Any ideas why linux is asking for j2re when i have downloaded it and installed the self extracting binary?

Any help would be great
