Hi, I have HP Zbook 15 with NVidia+Intel graphics. I have enabled NVidia to have better performance (discrete in bios). This requires pnpacpi=off in grub, for Ubuntu to boot into graphic mode with nvidia drivers.
And I think this option also disables laptop touchpad and keyboard. I don't see them in xinput. Both of them work in BIOS and when you boot live image. This all started with 18.04 and is the same in 19.04 and 19.10 with 5.3.0-19-generic So, yes, this option is definitely a problem for laptops and nvidia drivers. Any workarounds? Except using external USB keyboard and mouse... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1584479 Title: [MSI GP72 6QE Leopard Pro] acpi=off required to boot Status in linux package in Ubuntu: Incomplete Bug description: Hi, I just install Ubuntu 16.04 on my new MSI laptop G72 6QE.
