Hi
I await an answer with great interest to this one. Since my desktop became a 
bit cluttered and the number of files built up my desktop painting etc is 
slow especially if the internet is being accessed via eth0. Eth0 and desktop 
painting even interferes with sound. No such problems on suse 9.0 and the 
same kit. I often have 20 or more Konqs up.
3gig P4, 1gig 400 ddr, sata, linux nvidia driver. Intel motherboard
It just like a screwed up windoze installation.
