64 bit cpu-64 bit Ubuntu-are there 32 bit app issues?
 

I have 64 bit AMD cpu. Also 64 bit version of Debian. There are troubles with 32 bit application compatability.

Does Ubuntu have this problem? Will I have this problem if I use the 32 bit Ubuntu with 64 bit cpu?

Also, when I am asked, on the download page...
"What type of computer do you have?"
1. Standard personal computer (x86 architecture, PentiumTM, CeleronTM, AthlonTM, SempronTM)
2. 64bit AMD and Intel computers

I have AMD 64, but can I choose "Standard personal computer" so I get the 32 bit version?

To answer your questions....Yes.

You have a 64-bit AMD proc, which makes it x86_64 arch. That means that you can run....

IA-32 arch (standard PC, i386 based comp (now called x86))
x86_64 arch (AMD64, Intel EM64T, etc)


64bit Linux on a 64bit comp runs much faster then 32bit, at the cost of some compatitbility. My laptop (AMD Turion64x2) was running Fedora 7 (32 bit). The apps worked, but, wireless and sound did not. My sound card would not work with a 32bit kernel. Now that I'm running 64bit Linux, everything works.

Just wondering, what apps don't work?

Armanox.
Skype, flash player and java (and most likely other also) do not have 64 bit versions and the process for making 32 bit functional is over my head. Maybe somewhere down the road I can try it again, but for now I would just like to get a good Linux box up and running. I don't care about having the best of everything. I wish I would have known about this problem before I bought the processor.

Skype and Java I have yet to use in 64 bit Linux. I was aware of the issue with flash, but, the workaround for flash is very simple. Go ahead and try the 32 bit Ubuntu and see if all of your hardware works. If it does, then have fun!
