Hi all,
Last month, i downloaded and installed opensuse11.1 (x86) while my laptop is using Core 2 Duo processor, should i migrate to x64 kernel? How?
Thx in advance…
PS: Sorry for my bad English, i’m Indonesian.
Reinstall using the correct media, ie x64. That is the easiest route.
PS: Your English is fine. No need to apologize.
Reinstall is not only correct, it’s the only way. The architecture, 32bit or 64bit, is completely through the system.
Read and post a lot. You will learn a lot about linux, and improve your english as well.
To add to what other posters have mentioned, the kernel requires the libs that are present in the 64bit install for a functional OS. You can install the other kernel, but other pre-requisites will need to be met.
As the others said, to take full advantage of x86_64 you’ll need both drivers/kernel to be x86_64 as well as the software.
Although I assume you could all do it manually you’d end up with a lot of 32 bits software installed you’d no longer need.
Best way about it would indeed to do as suggested and simply reinstall and then using the x86_64 cd-rom or dvd.
Also remember that just because you’ve got a 64 bit processor, it doesn’t mean you’re necessarily better off with the 64 bit version. I think particularly if you don’t have much RAM it can actually be slower, and it can (occasionally) be harder to find software…
ok…thank you for all replies…
So, i think the conclusion is re-download the distro, and take the x64 version of openSUSE 11.1, right? fyi, i have 4 GB of RAM and now in my x86 kernel detected as 3 GB. That’s why i want to upgrade to 64bit version 
Thanks for all answers ^^
You might be able to access the rest of that on 32 bit using the PAE kernel, which should be fairly straightforward to install.
I’m no expert, but I think 4 gig should be enough to happily run the 64 bit version though. There are advantages either way.
