[Kernel-packages] [Bug 1916971] Re: After fresh Ubuntu 20.04 install, downgrading Nvidia driver doesn't update nvidia modules in kernel

2021-03-21 Thread Ubuntu Tinkerer
I don't understand. I currently have nvidia-driver-460 and linux kernel
versions 5.8.0-43 to 45 installed (45 is being used). But I have no
linux-modules-nvidia-460 packages installed. E.g. I don't have linux-
modules-nvidia-460-5.8.0-45-generic and neither for 44 and 43. Is this
ok or should I install linux-modules-nvidia-460-5.8.0-XY-generic.

If the linux-modules-nvidia-460-5.8.0-XY-generic packages are not
necessary for my system then why were they pre-installed in the first
place, especially since they caused problems for me when I wanted to
downgrade nvidia-driver-450?

Please if you can answer my questions here and if you don't regard these
as issues then close this bug report.

  SYSTEM:

  Laptop: ASUS ROG GL552VW
  OS: Ubuntu 20.04.2 LTS
  GRAPHICS: Nvidia Geforce GTX 960m AND Intel HD Graphics
  Linux kernel version: 5.8.0-44-generic

  SUMMARY:

  From a fresh working install of Ubuntu 20.04, I downgraded from
  nvidia-driver-460 by installing nvidia-driver-440 (which actually is a
  transitional package to nvidia-driver-450 but I didn't know this).
  After reboot I couldn't reach login-screen and instead got a black
  screen.

  Problem was that sudo apt-get install nvidia-driver-440 did not insert
  nvidia modules v450 in kernel since never versions v460 were found.

  This was solved by uninstalling linux-modules-nvidia-460 packages and
  instead installing linux-modules-nvidia-450 packages (see WORKAROUND
  below for instructions).

  STEPS TO REPRODUCE:

  Install Ubuntu 20.04. During installation, allow for the installation
  of proprietary drivers.

  Once Ubuntu 20.04 has started, open a terminal and run the following:

  sudo add-apt-repository ppa:graphics-drivers/ppa
  sudo apt-get update
  sudo apt-get install nvidia-driver-440
  sudo shutdown reboot now

  PROBLEM:

  After reboot, you can't reach login screen. Instead you get stuck
  during bootup.

  WORKAROUND:

  INSTRUCTIONS. PAY ATTENTION TO WHAT NVIDIA DRVER AND LINUX KERNEL
  VERSIONS ARE RELEVANT FOR YOU! Run dpkg --list | grep linux-image to
  see what linux kenrel versions you have installed.

  Remove the linux-modules-nvidia-460 packages and install the
  corresponding linux-modules-nvidia-450 packages. In my case I had
  Linux kernel versions 5.8.0-44-generic and 5.8.0-43-generic installed
  so I did as follows from recovery mode with network (instead of
  entering recovery mode, you should be able to press CTRL+ALT+F1 from
  the blank screen after bootup, login with username and password and
  then running these commands):

  sudo apt-get autoremove --purge linux-modules-nvidia-460-5.8.0-44-generic 
linux-modules-nvidia-460-5.8.0-43-generic
  sudo apt-get install linux-modules-nvidia-450-5.8.0-44-generic 
linux-modules-nvidia-450-5.8.0-43-generic
  sudo shutdown reboot now

  QUESTION:

  Why was the linux-modules-nvidia-460 packages installed by the Ubuntu
  installer to begin with? I ask since I later removed the linux-
  modules-nvidia-450 packages (OBSERVE: 450, not 460) and used the
  Additional Drivers GUI to update back to nvidia-driver-460. Now linux-
  modules-nvidia-460 packages are NOT installed but the following still
  outputs 460:

Sorry for my late reply.

What do you mean by "... in the live session"? Instead I executed that
command from my Ubuntu installation (where I observed the bug) and the
output is here further below.

@Dimitri are you saying that securedboot devices should avoid using the
device drivers PPA? Also I'm currently on nvidia-driver-460 but I have
no linux-modules-nvidia-460 packages installed. My system seems to work
correctly. Is it OK that I don't have the linux-modules-nvidia-460
packages installed?

[Kernel-packages] [Bug 1916971] Re: After fresh Ubuntu 20.04 install, downgrading Nvidia driver doesn't update nvidia modules in kernel

2021-03-05 Thread Dimitri John Ledkov
Can you please provide the output of:

$ sudo ubuntu-drivers list

In the live session?

There are two ways to get the nvidia kernel driver. One option is to
compile it from scratch on the users machine with dkms. THe other option
is to install a metapackage linux-modules-nvidia for the appropriate
kernel flavour and the appropriate nvidia revsision which provides a
prebuild, not linked, and secureboot signed nvidia module.

So as to why the dkms one will not work or load on secureboot
machines, unless one goes through cryptic MOK key enrollment procedure
during boot.

The secureboot signed nvidia module works on secureboot machines without
any additional steps by the user.

But the caveat is that the secureboot signed ones must be kept in
correct tandem with the kernel flavour & nvidia revisions.

Anything you install from the PPA will not be secureboot signed, and
thus need MOK signing.
