Is Kubuntu 64bit using a 32bit kernel?

[michel]

Greetings,

I installed Kubuntu 64 bit and it is seeing and managing my 8M of ram.

Today I had a kernel upgrade and wanted to see what kernel version I was now using and I got this: 3.2.0-33-generic-pae. Is Kubuntu 64 a PAE 32 bit version?

I've never seen a kernel switch from 64-bit to 32-bit on its own. Since PAE allows a 32-bit kernel to see more than 4 GiB RAM, I'm wondering if you perhaps installed 32-bit initially? Let's take a look at a couple things.

First, the output of:

dpkg -l | grep linux-image

Also, please paste the contents of /var/log/apt/history.log in a new page at http://paste.kde.org and reply here with the URL to that page.

Ah, as I suspected. All your kernels are 32-bit, and so are all your installed packages (as the "i386" architecture indicates). So yes, you initially installed the 32-bit edition of Kubuntu. If you want 64-bit, you'll need to reinstall. There's no reliable way to perform an in-place replacement.

Oops! I think I'll stick to 32.
