    Question about the Swap space

    Now if I have 6 GB of RAM on Ubuntu 32bit, do I still need to create a swap space? What if I have 4GB of RAM? Shouldn't both RAM and Swap never exceed 4 GB on a 32bit system?

    It depends on your usage, but, most often then not, with 4GB of RAM you'll only need swap for suspense to disk, aka hibernation. I only have 1GB of RAM and swap is only rarely used.

    I'm asking about whether the combo of RAM and swap can exceed 4Gb!

    The server install of Ubuntu is the only way to use more than about 3GB of memory with the 32 bit version. You need the 64 bit version to utilize more memory with the standard desktop installs.

    Swap is for overflow but is just where memory is copied. It also is used for hibernation. With the standard 32 bit version having swap over 3GB is also probably a waste.

    Do you have any particular problems with the 64bit version of Ubuntu?

    I've heard that Java and flash have problems with the 64 bit version; however, as a Java developer I can't afford having problems with Java

    I run Ubuntu 64bit and I think most flash problems have been sorted out now and it is no worse that the 32bit version. I am not as sure about java but as far as I know it is fine, you might want someone else's input on this.

    It is probably worth trying the 64bit version first because it might work fine for you. If it doesn't and you have to use the 32bit version you can use PAE to address more than 4GB of RAM, but I would only recommend you use PAE if you absolutely need to see all the RAM because it can introduce other problems.

    It'd be awesome if someone can tell me what isn't gonna work on the 64 bit version, because I'll lose about 2GB of memory if I stick with the 32bit version.

    I guess I'll move to the 64bit edition. Hope no software breaks!

    Edit: Unfortunately, there are no Canon printer drivers for the x64!
