NVIDIA 590 driver drops Pascal support

With the update to driver version 590, the NVIDIA driver no longer supports Pascal (GTX 10xx) GPUs or older.

Impact: Updating the NVIDIA packages on systems with Pascal, Maxwell, or older cards will fail to load the driver, which may result in a broken graphical environment.

Intervention required for Pascal/older users: Users with GTX 10xx series and older cards must switch to a legacy driver to maintain support:

  • Install the official linuxXXX-nvidia-575xx, linuxXXX-nvidia-570xx, or related DKMS packages.

mhwd now support multiple profiles which should also help in a more automatic way to choose the proper driver for your NVIDIA card.

.NET packages may require manual intervention

2025-12-11 - George Rawlinson

The following packages may require manual intervention due to the upgrade from 9.0 to 10.0:

  • aspnet-runtime
  • aspnet-targeting-pack
  • dotnet-runtime
  • dotnet-sdk
  • dotnet-source-built-artifacts
  • dotnet-targeting-pack

pacman may display the following error failed to prepare transaction (could not satisfy dependencies) for the affected packages.

If you are affected by this and require the 9.0 packages, the following commands will update e.g. aspnet-runtime to aspnet-runtime-9.0:

pacman -Syu aspnet-runtime-9.0

pacman -Rs aspnet-runtime

mkinitcpio v40 disabled fallback image creation for new installs

mkinitcpio v40, packaging changes and kernel-install - Arch-dev-public - lists.archlinux.org
This is only affects new installs as we can’t change the hook files on existing installs.

To disable fallback image creation on older installed systems

  • Change PRESETS=('default' 'fallback') line to PRESETS=('default') in the respective .preset files in /etc/mkinitcpio.d/.
  • Regenerate initramfs - sudo mkinitcpio -P
  • Update boot loader - sudo update-grub

Warning
Disabling all fallback initramfs generation will deprive you of another option to boot into the system in case a default initramfs fails. Before proceeding, make sure you have a bootable installation medium for rescue purposes on hand.
