    Ubuntu fails to boot (Nvidia hybrid)

    Hi,

    I have a machine with Geforce 960M + Intel 6700 HQ. But I haven't been able to boot Linux on this machine for the last 3 months.

    So far I've tried Ubuntu 24.10, 24.04, 22.04, Fedora 40 and Manjaro 24.0.5. All to no avail.

    I have already filed a bug report on launchpad: https://bugs.launchpad.net/ubuntu/+bug/2071680

    And several other posts on multiple forums:
    Ask Ubuntu
    : https://askubuntu.com/questions/1518...ybrid-graphics
    Nvidia developer forums
    : https://forums.developer.nvidia.com/...ce-960m/307298
    Manjaro Linux forum: https://forum.manjaro.org/t/manjaro-...-hybrid/166320


    Unfortunately the failed boots aren't captured by journalctl, that's why I haven't been able to trace the issue so far.

    Journalctl issue: https://askubuntu.com/questions/1520...via-journalctl

    So all-in-all, any help or suggestion leading to at least tracing the issue would be a sign of hope, and I very much would appreciate it.

    Re: Ubuntu fails to boot (Nvidia hybrid)

    xashyar - Hello

    When you boot up - Ubuntu - can you boot to Grub's boot menu ?

    If so - get to a recovery console as a platform from which to work/explore.
    At grub's boot menu > advanced > recovery kernel > root shell.

    Then we can carry on.

    else we have to do something different

    Yess, sure I can. I can also boot into Ubuntu, but only via recovery mode.

    xashyar

    Then my next thought is to know what Nvida driver(s) is installed.
    Code:
    dpkg -l | grep -i nvidia
    where we are looking for the 550 version - only - driver; installed from our software repository.

    gots to be a reason

    I'm currently running nouveau (note that it doesn't work/boot either), but I have previously tried 560, 550, 535 and 470:

    There was only 1 time, where 470 worked, but it stopped working after upgrading from 470.239.06-0ubuntu2 to 470.256.02-0ubuntu0.24.04.1.

    Is there any way to switch back to 470.239.06-0ubuntu2 ?

    Re: Ubuntu fails to boot (Nvidia hybrid)

    xashyar - Well --

    Lots of attempts

    Let's try this-a-way
    Secure boot disabled in Bios - as the driver is 3rd party.
    Run in terminal:
    Code:
    dpkg -l | awk '/^rc/{print $2}' | xargs sudo dpkg -P
    sudo apt update
    sudo apt upgrade
    sudo ubuntu-drivers autoinstall
    removes the cruft:
    The state is rc, -the package is removed, but the config files are not removed-
    While there is no built in way to remove all of your configuration information from your removed packages you can remove all configuration data from every removed package. To purge all removed but not yet purged packages.
    and:
    autoinstall to allow the kernel to install the Nvidia version driver it deems fit (I expect the 550 version).

    Reboot to see the effect.

    is this a Yes !

    Re: Ubuntu fails to boot (Nvidia hybrid)

    Bashing-om - unfortunately nothing changed.

    'autoinstall' installs the 560 version (as I'm running 24.10). But I get the same results (I have tried many clean-installs before as well, but they don't help either, it's the same even on Fedora, or Manjaro).

    This is the screen I get when the booting freezes/fails:

    xashyar; Yuk -

    I am really floundering here too - as I have no idea what "EFI stub" is telling us.

    However -- might give us a hint of what the kernel thinks:
    Code:
    less /var/log/gpu-manager.log

    Re: Ubuntu fails to boot (Nvidia hybrid)

    Bashing-om; Thank you for your patience!

    I have prime-select currently set to on-demand, and it's worth noting that if I switch it into nvidia, I get a black-screen even if I boot via recovery mode from the grub menu.

    Here's the log output, and nvidia is shown to be blacklisted:
