After hearing many complaints about trouble using Fedora Core 6 with a 64 bit processor, I decided to test it myself. For the most part almost everything is identical however there were some issues I found. I decided to write a mini-guide with some notes and tips for 64 bit.
The only seriously confusing problems I had was with the co-existing of both i386 and x86_64 libraries and packages, commonly referred to as multilib. The rpm command is improved when adding:
to the file: /etc/rpm/macros
I noted that having duplicate libraries and applications did make the installation a bit larger, apx. 0.5GB. While this isn’t very large, I could not figure out what was the reason that some 32 bit apps are included while others aren’t.
Additionally the Nvidia driver installation had some yum problem due to some 32 bit dependencies. I removed those and that problem was resolved.
I currently have a power management problem with kernel 2.6.20-1.2933.fc6 x86_64 as my desktop won’t properly suspend (mode S3).
In conclusion I found the multilib to be such a nuisance. I would consider switching entirely to 64 bit if there was perfect 64 bit support for everything. In that I mean if there was absolutely no need for any 32 bit parts. I didn’t notice a significant speed increase and I am not aware of any major benefits I’m losing by staying with 32 bit Linux.
