Kubuntu - How to tell if I'm running 32 or 64 bit version.

[peterv6]

I just received my Kubuntu 9.10 CD from Canonical. I installed it on my system, but I don't know if it's 32 or 64 bit. (See my system configuration below.) I found a C program online that says it can determine which version I'm running, and it said 32 bit. (Of course I don't know if that program works or not.)

   1 #include <stdlib.h>
   2 #include <stdio.h>
   3
   4 int main(void) {
   5  printf("%d\n", (int)sizeof(long)*8);
   6
   7  exit(0);
   8 }

./bits
32

What I'd like to know is:
1. What is the definitive method of confirming which bit verson of Kubuntu I'm running.
2. Are there 2 separate versions of Kubuntu (32 or 64)?
3. If there's only one version, how is it determined if it's run in 32 or 64?

I'll really appreciate any help.

You have 32-bit. You would have had to consciously choose the 64-bit CD.

If you open the terminal and enter

lsb_release -a

I think it will tell you.

1. What is the definitive method of confirming which bit verson of Kubuntu I'm running.

You can use commands 'arch' or 'uname -m'.
If the output is 'iX86' you're running 32-bit, 'x86_64' means 64-bit

Thanks for that info. Now for the big question. How do you get Kubuntu running in 64 bit mode? I have a 64 bit processor, but I don't know if I have to install a different version of Kubuntu, or if there's something else going on that I don't know about. I do know, that a lot of software I run on my OS X machine are 64 bit aps running in 64bit mode.

Pretty sure it needs to be re-installed:

Right -- 32-bit and 64-bit are separate architectures. You have to choose which to install:

You do have to install a different version of the OS to go to 64 bits. Under normal circumstances, i.e. if you were running *buntu directly on your hardware, I would say just install the latest edition of the Kubuntu 64 bit version from a (free) CD, or, (for quicker service), from a CD vendor for a couple of bucks.

However, in your case there is another (possible) issue: You are running Kubuntu in a "virtual machine", if you are running it under Parallels. I'm not familiar enough with Parallels to know whether it emulates a 64 bit processor or a 32 bit processor. I would suspect that it would be MUCH easier to stay as close as possible to the native HW, but the Apple developers may have chosen to do something else.

Moreover, you have to ask yourself whether there is any advantage to using the 64 bit version over the 32 bit version. My response (I use the 64 bit version) would be: probably not, unless you do extensive image processing, run mathematical simulation software, or something similar. Ask yourself if you remember the last time that you entered a command or clicked on something and had to wait for a response, or for a program to finish. If the answer is that you can't remember, you paid too much for your computer. If it was a couple of weeks ago, and you're not going to be doing whatever caused the delay again in the near future, wait for the next release (less than two weeks away) and go 64 bits then instead of upgrading. If it was a few minutes or even hours ago, go for it right now.

On my machine, the easy way is to open the System Setting panel and click on the About System button in the System Information section.
It comes up and tells me what version of Kubuntu is installed, what version of the Linux Kernal is installed, whether it is running in 32 or 64 bit mode and how much RAM is available to the system.

Click, Click, Click. Done.

uname -i

is the simplest IMO
