Hi i'm running Kubuntu 6.06 on an AMD 3800+ X2 PC. How can i tell if both cores have been recognized?

On my core2duo when I do a:
cat /proc/cpuinfo
it will have two seperate sets of info for each core.

I'd guess the same is true for your AMD.

Re: dual core CPUs recognized?

What kernel are you using? It probably doesn't have SMP support.

uname -a

Post that.

2.6.15-27-386 #1 PREEMPT Fri Dec 8 17:51:56 UTC 2006 i686 GNU/Linux

I think you're going to need to install the linux-k7-smp kernel. Search for that or smp in adept and make sure it's the only choice though.

Re: dual core CPUs recognized?

hmmm... will the K-7 kernel work with the Athlon 64? I'm running 32 bit Kubuntu 6.06 on an Athlon 64 3800+ X2, should i still be installing the K-7 one?

Re: dual core CPUs recognized?

I'm pretty sure that's the only smp kernel on dapper. edgy uses a -generic kernel that has the smp support in it.

I don't have a dapper system to check so I just searched on pacakges.ubuntu.org for some info. I was kind of hoping someone else would jump in with an answer.

As long as you don't uninstall the old kernel you can always boot back into it from grub if you run into a problem.
