[Bug 1916971] Re: After fresh Ubuntu 20.04 install, downgrading Nvidia driver doesn't update nvidia modules in kernel
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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916971 Title: After fresh Ubuntu 20.04 install, downgrading Nvidia driver doesn't update nvidia modules in kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-460/+bug/1916971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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?

[Bug 1916971] Re: After fresh Ubuntu 20.04 install, downgrading Nvidia driver doesn't update nvidia modules in kernel
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. ** Also affects: nvidia-graphics-drivers-460 (Ubuntu) Importance: Undecided Status: New ** Also affects: ubuntu-drivers-common (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916971 Title: After fresh Ubuntu 20.04 install, downgrading Nvidia driver doesn't update nvidia modules in kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-460/+bug/1916971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In kern.log, look for rows near the search string "API mismatch".

** Summary changed: - After fresh install, downgrading Nvidia driver doesn't update nvidia modules in kernel + After fresh Ubuntu 20.04 install, downgrading Nvidia driver doesn't update nvidia modules in kernel ** Description changed: SYSTEM: Laptop: ASUS ROG GL552VW - OS: Ubuntu 20.04 + 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). After reboot I couldn't - reach login-screen and instead got a black screen. + 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 dropping into safe mode and uninstalling linux- - modules-nvidia-460 packages and instead installing linux-modules- - nvidia-450 packages. + 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: 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 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: modinfo nvidia | grep -i version LOG: This is a relevant part of /var/log/apt/term.log for when I installed nvidia-driver-440 nvidia.ko: Running module version sanity check.
