    Re: Xubuntu 12.04 Non PAE

    Never tinkered with boot/grub/grub.cfg before. Noted the "DO NOT EDIT THIS FILE" remark - will it be overwritten? Where would I add forcepae?
    To put forcepae into the grub.cfg file you need to edit the etc/default/grub file and put your changes into the
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash forcepae"
    line.

    Then run
    Code:
    sudo update-grub
    to add the parameters to the grub.cfg file.

    Good Luck

    Re: Xubuntu 12.04 Non PAE

    Okay, this did the trick, I think - thanks everybody. Got a few errors in the process (14.04 still beta, right?). I guess the procedure for reviving old non-PAE machines involves a bit more than than just booting with the forcepae boot parameter. Summing up, would this be the right process?

    • Booting with the forcepae boot parameter
    • Install Ubuntu
    • Add forcepae to etc/default/grub (e.g GRUB_CMDLINE_LINUX_DEFAULT="quiet splash forcepae")
    • Execute sudo update-grub
    • Reboot
    • Execute sudo apt-get update
    • Execute sudo apt-get dist-upgrade
    • Execute sudo apt-get -f install
    • Take what ever updates available...

    Should we have this included somewhere for easy access to those needing support for using the forcepae feature? I can not be the only one, right?

    You are the only one that I have heard of. Before broadcasting the solution I think it's better to see if others get into the same problem.

    Thanks for chipping in, Devzero and Plucky.

    Unless this is the same person, I think it's safe to say that the forcepae option needs to be manually added to allow kernel updates: https://bugs.launchpad.net/ubuntu/+s...x/+bug/1307105

    It's not me, but it is a very consistent description. I can add that I have the exact same issue with a Dell Latitude D505 (Celeron M), but now I know the fix...

    It is also my experience (from my IBM Thinkpad T42 with a Pentium M processor), that forcepae must be added in grub for kernel upgrades to work.

    The end result will be similar to that of fake-pae (that was used in previous versions).

    Tainted usually means you're running a binary driver, and kernel devs won't accept bug reports. I don't see how that applies here, since the Pentium M's actually support PAE, but don't report it correctly. I guess if the forcepae option works on other CPU's that really don't support PAE, the tainted label would be justified, but I don't know enough about the forcepae and what systems it runs on to say for sure.

    Re: Xubuntu 12.04 Non PAE

    I installed 3.13.0-17-generic #37 and dist-upgraded in several steps to 3.13.0-24-generic #46. Only specified forcepae at install, no manual tweaking of Grub or the like. Everything works.

    If we can use this case for comparison I'm ready to do some testing.
