"i just installed debian gnu/linux, to be exact it was yesterday. but i've ran into two major problems!"
What version of Debian did you install? woody, sarge, sid, what?
"i changed the kernel from 2.4.something to 2.6.7, configured it for the machine on which it was going to be used, compiled it and everything was running smooth. i put on the nvidia drivers. the x server was running normally. then i had to install gnome and kde. the kde-core was installed, but gnome won't install. i'm using the non-free, main and unstable packages."
So, you are using Sid? The significance of this is that Gnome2.6 is only available on Sarge and Sid. I think KDE 3.2 is only available on Sid, but i'm not sure, due to the fact i don't use any of them.
"the "apt-get install gnome" gave me some error messages that some packages were needed for the installation but they weren't going to get installed."
Correct. I'm on Sid/kernel 2.4.26 and after reading your posting, i tried it with a -u flag and gives me the same message, you will have to wait for the bug to be solved, go to the #debian channel in the IRC and ask the gurus. From the #debian:
"bts is the Bug Tracking System for Debian packages,
http://bugs.debian.org/ or to go directly to the bug page for a particular package, try
http://bugs.debian.org/packagename or anyone running unstable who's unable to check the BTS should be shot on sight. apt-get install reportbug, and check out querybts too. sid users, apt-get install apt-listbugs"
hehe
install 'report-bug'
it will keep you abreast of the situation when you try to install it.
"my other big problem is with the two cd recording devices."
i can't help you there either, it seems to me that should be appended in the grub/lilo menu.lst/lilo.conf depending on what you use.
"could anyone help me with these problems? how to i install the latest gnome and make the writing devices work with the 2.6 kernel?"
At the moment you can't until the bug is resolved, BTS and #debian will announce it.
go to the #debian in the irc, for the latest, before you go there, read their wiki:
#debian FAQ Wiki
http://www.linuks.mine.nu/debian-faq-wiki
this is a must, otherwise they will tell you to read it, those people don't suffer fools lightly, i know, i was one of those fools.
and ask them what's the latest on that bug, because as of 2 days ago Gnome2.6 could be installed on Sarge and Sid.
