Ubuntu – Is it possible to boot without adding `pci=nomsi` or `acpi=off` to the grub command line


I have an ASUS X64SL laptop with Intel Core 2 Duo P8400 CPU.

When I want to boot with Linux I have to add to the grub command line either pci=nomsi or acpi=off.

Is there another way to boot without adding any of these two lines?

Follow these steps precisely

  • Start your system as your traditional way :) Then open terminal(Ctrl+Alt+T) and execute these commands:

    sudo cp /etc/default/grub /etc/default/grub.bak
    sudo gedit /etc/default/grub

    once grub is opened in gedit replace



    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

    Save and close gedit window.

  • Update grub and restart your system:

    sudo update-grub
    sudo reboot

Your system should starts normally. Reply if something goes wrong..
