can i change from 32 bit to 64 bit after install is done

Thanks shane fagan, that solved my question.

I prefer the 32bit version. It's faster imo, uses less Ram, better repositories and still does all the multi-threading that other OS's only have in their 64bit versions!

Linux is built from a Unix base which had multi-everything from very early on. Other OS's are still trying to catch up :) "Conky" is great for looking cool on your desktop and showing graphs of each cpu's usage and ram usage and stuff, highly configurable and very light on system resources.

Good luck and regards from

my system is an amd athlon 64 4000+ 2.6ghz stepped up from 3800+ 2.2 with 2 g of ram {pc6400} stepped up from pc5300 512 g ... my install is only 2% of my hard drive [ubuntu 9.04 ] it replaced vista home which used 32% of my hard drive. i am happy with the way it works just thought 64 bit might be better, my start time is 1 min 20 seconds .. my first install of ubuntu was 7.04 went back to microsoft for about two weeks then deleted it . i tell everyone i will not give up my ubuntu for no reason and no one.....the only thing i would like to see in the ubuntu world is some better games .i have tweaked everything i can for speed , my internet speed is 10 meg + for down load and .83 meg upload and cost less than $ 50.00 a month ... the more i learn the more fun i have.. thank you everyone

Lol, that all sounds all good :) I keep a dual-boot in case i want to go back into Windows for anything but since my neighbour got Half-Life2 working in Wine i think i can still manage to avoid it :)

Games, multimedia apps and hardware drivers seem to be the majr stumbling blocks at the moment. Just 1 OpenSource driver per device would cover all the linux's and Macs too. OpenGL instead of just DirectX would again cover all linux's and Mac's. lol, it's getting better. I try to write off an email to a different manufacturer/games org each week but keep it polite.

I'm sure lots of us do stuff like that to show there is an increasing market out here!

lol, good luck and regards from

Dual-boots a great way to learn linux at your (or their) own pace. hassle free and gently sounds good to me ;)
