![]() When every option was closed except reinstalling, a bright ray of hope shined - Systemrescue disk allowed me to login to the Arch installation via GDM-greeter window straight into my desktop!! Admittedly, it was freezing intermittently but allowed sufficient time in between freezes to work in terminal to remove windows entry from /etc/fstab file and removing the extra user I created. Rescuzilla image couldn't be selected, so could not be restored. Fast boot disabled, Windows shut down properly after error checking didn't help. When we finally switch away (either through programs like plymouth or manually) the content is lost and the VT reverts to text mode.Boot the iso : Booted but couldn't mount - "windows not clean". This allows the bootloader to insert a graphical splash and have the kernel maintain it until the OS splash can take over. Introduce a new VT mode KD_TRANSPARENT which endevours to leave the current content of the framebuffer untouched. UBUNTU: SAUCE: vt - maintain bootloader screen mode and content until vt switch Something else in the Focal Fossa kernel has changed since Bionic that causes including this commit to freeze X.Ĭommitted by Andrea Righi 14.56.25 +0100Ĭommit be779101bc2fc3f675a1df11c4abaec017add984Īuthor: Andy Whitcroft Wed Apr 16 19:40:57 2014 +0100 This same code is in Bionic kernels also but does not cause X to freeze with them. I have also made an bug report about the issue. With contents: options nvidia_drm modeset=1Īnd since nvidia_drm is not built into the kernel, this should be the preferred way.Īfter reversing this commit, I was able to build latest Focal Fossa 5.4 kernel that did not cause X to freeze. Like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia_drm.modeset=1"Īfter this we need to run sudo update-grub, to add the parameter to the GRUB configuration at /boot/grub/grub.cfg.Ģ: Instead of the kernel command line parameter, the parameter can be defined in modprobe's configuration:Ĭreating file (name doesn't matter as long as it is in /etc/modprobe.d and ends. ![]() in the two following ways:ġ: Modifying Grub's configuration, so that the parameter is added to kernel command line when booting, by editing the file: /etc/default/grub Without building kernel with the commit reversed, the work-around with all Focal Fossa 5.4 and 5.6 kernels I tested was using nvidia_drm.modeset=1. I found the Ubuntu kernel commit causing this for me. Sudo apt-get install nvidia-graphics-drivers-440Īfter the installation adding the kernel parameter nouveau.modeset=0 is not necessary anymore. sudo add-apt-repository ppa:graphics-drivers/ppa The xorg-edgers PPA does not provide the drivers anymore and was replaced by GPU Drivers PPA. This package was only updated for Ubuntu 20.04 two days ago (22 April 2020), so it's quite bleeding edge, and might be why your prior testing with a nvidia 440+ series did not work.Īs you have to find NVIDIA drivers (440.31+) which support the Linux 5.4 kernel shipped by Ubuntu, you could also install the latest official NVIDIA drivers. ![]() Generally it is recommended to use the NVIDIA drivers from the restricted Ubuntu repositories. Highlight the Ubuntu entry in the GRUB boot menu and press the E key.Īdd nouveau.modeset=0 (you should use this instead of instead of nouveau.nomodeset=0) to the end of the linux line - press F10 to boot.Įnter user name and password - execute: sudo apt-get update To install the latest NVIDIA proprietary drivers, you may need to disable the open source drivers first on boot:īoot the computer and hit the Shift key to bring up the GRUB boot menu. That said, if you want to go down this path, you'll need to ensure the version of nvidia-* binary drivers which you install provides support for the Linux 5.4 kernel shipped in Ubuntu 20.04. The drivers are completely outside of the Linux kernel, and so kernel developers and Linux distributions like Ubuntu shouldn't provide end-user support for them. If you choose to use proprietary binary drivers (as the nvidia-* drivers are) then you really need to approach NVIDIA to get support for them. ![]()
