    Default Default or Pae?

    Hey all,

    I couldn't find a better place to post this, so here it goes: what is the meaning of having the pae version of a kernel? Up until recently, I always had the default version, but one day my kernel updated, and now it runs the pae version. So, what is the difference between the two?

    Thanks.

    Hi
    PAE means Physical Address Extension basically it lets a 32bit system
    access more that 4GB of RAM. Google on PAE+Kernel should give you
    plenty of information.

    It seems to be the Nvidia-driver installation that can flip you from
    default to pae [needlessly, in my view...I consider it a bug.
    I forced mine back to default, as have a few others]

    How would I go about doing that considering I have less than 4GB of RAM?

    Also, is there any real advantage to doing that?

    Yeah, that was my thought too! [I have just 1GB of memory.]
    Just go into the usual 'Install Software', type in 'kernel', and you
    should see, among others, the two packages 'kernel-default' and
    'kernel-pae'. Click on the first to install it, and keep clicking on
    the second until it's marked to remove it, go.

    Slight warning: This is potentially an 'intermediate/advanced' move,
    as there are the usual 'side-effects' of changing kernels: X-Windows
    may break, as it probably drops you back to non-proprietary video
    driver), and the grub-menu stuff needs to get tweaked (hopefully,
    automatically).

    But, you have > 100 posts, so I'm betting you can handle any
    hiccups.

    Advantages: None that I know of, other than being more 'standard'.

    Good 'ole KISS method.

    For now, I think I'll keep what I have at the moment, but I may consider it for the future.

    Been having a few problems with Factory repositories, so I'm going to try and stay clear of any hiccups at the moment.

    Thank you, though.
