With PAE you can use the RAM in total. However, each process is still
limited to the maximum addressable 2^32 bytes. So if you want to say, let
GIMP open a 4 GB image, you cannot do it on a 32-bit kernel without swapping.

Not that it would be advisable to do so.

We have not really had a team meeting as such for the UK Local

If you've a 64-bit CPU there's no reason to run a 32-bit kernel. You'd
likely be hard-pressed to tell the difference between them, though.

I've typically gone for a 32-Bit distro too in the past but have 
recently made the switch to 64-Bit.  Not had any issues with it, just 
seems to work just as well as 32-Bit distros.


IIRC if you want to run processes with more than 4GB memory then you 
need a 64-Bit OS, but even with 4GB Ram you can use all the memory if 
you enable the kernel with PAE support.


I've also found that Virtualbox seems to run a little better on a 64-Bit 
OS too, even with only 2GB Ram.

Re: [ubuntu-uk] 64-bit vs 32-bit

[Tyler J. Wagner]

I have run 64-bit on the desktop for almost 5 years now. Even 32-bit apps
like Skype run just fine now, thanks to multi-arch. Just use 64-bit, and
install what you want from the package manager. It'll work.

Hi
I'm thinking about upgrading to Xubuntu 12.10. It will be a fresh install. So 
far I've always gone for the 32-bit version and had next to no problems, either 
with the OS or applications. Conscious of the need to keep up with the times, 
I'm considering 64-bit next time. Are there any real advantages or would I be

AIUI at the moment you must use the ChromeOS kernel with Ubuntu's
userland and some things don't work.

TBH I don't really see the point of x86 Chromebooks. Why not just have
a cheap laptop? But the ARM ones really appeal. Cool running, no
heatsinks or vents to clog with dust, no whining fans, and twice the
battery life from a small, thin, light unit. I'll give up a bit of
compatibility and performance for that!

Here's a chap who's been tinkering with Ubuntu on Chromebooks:
http://chromeos-cr48.blogspot.co.uk/2012/04/chrubuntu-1204-now-with-double-bits.html

He hasn't tried it on the new Acer but thinks the above instructions should
work. He's also got a rough guide for the ARM Chromebook.
