I want to install Ubuntu 11.10 in my Acer Aspire 5755G (with Core i5 processor, 8 Mb Ram and nVidia GeForce GT 540M) I would like to know if I should install the 64-bit or the 32-bit version. Thank you for the help.

8Mb RAM? Is that a typo? – Alexandre Jasmin Oct 21 '11 at 19:29
That was already asked (several times): – Maxime R. Oct 21 '11 at 19:52
Try to take the modern version of the nvidia drivers directly from and install them. In any case you can try nouveau drivers. – Oleksa Nov 4 '11 at 18:37

You should install 64-bit. You have a modern 64-bit processor and plenty of RAM. It's no longer the case that the 64-bit version is less stable, and virtually all software is available for both platforms.

I would say the only reason you should consider installing the 32-bit version is if there's some key piece of software that you need which is only available as a 32-bit version.

I would suggest a 32-bit. As it will be installed with PAE kernel, you will not have any probs with 8 Gb RAM usage. I think there are more 32-bit applications, so if you don't have any special requirements for particular applications go for 32-bit Ubuntu !

Good luck.

That is a fairly bad advise. PAE slows down your system and there's really no reason not to use 64bit anymore. – Jo-Erlend Schinstad Oct 24 '11 at 0:22
@Jo-Erlend It depends on software and hardware drivers your system must (!) use :) Sometimes there are 32-bit software/drivers only :) – Vincenzo Oct 26 '11 at 7:02
Very rarely. That was a common problem in 2006 and so, but these days, most everything is availble as 64bit and you can often use 32bit stuff as well. – Jo-Erlend Schinstad Oct 26 '11 at 14:33
@Jo-Erlend I fully agree with you :) Now most of software have 64-bit as a primary version. – Vincenzo Oct 27 '11 at 7:13

64-bit is the best choice for your hardware.
