Changelog:
– Downgraded Nvidia drivers to production 535.146.02. Unfortunately 545 drivers were not stable for all users and had various issues.
– Added ‘nobara-nvidia-new-feature’ repo, disabled by default. For users who want to try the 545 drivers you can do it this way:


sudo dnf update nobara-repos --refresh
sudo dnf4 config-manager --set-enabled nobara-nvidia-new-feature-39
sudo dnf update --refresh
akmods

then run the Update System app and reboot. It should sync you to the 545.29.06 drivers.

If you want to downgrade back to 535.146.02, disable the repo:

sudo dnf4 config-manager --set-disabled nobara-nvidia-new-feature-39
sudo dnf remove kmod-nvidia*
sudo dnf distro-sync --refresh
akmods

then run the Update System app again and reboot.

– Added ‘update-grub’ alias for grub2-mkconfig -o /boot/grub2/grub.cfg. This should help users coming from ubuntu based distros
– Added gstreamer1-plugins-bad-free-extras package to the ISOs and to the media codec package fixups. This allows av1 playback in mpv
– Updated explicit sync patches for xorg-x11-server-Xwayland — this fixes the freezing happening in a VM with llvmpipe and chrome or zenity, and fixes xwaylandvideobridge freezing with llvmpipe as well.
– Updated xwaylandvideobridge so it runs on llvmpipe again (we previously patched it not to due to the Xwayland explicit sync patch bug)
– Updated to kernel 6.6.8. KERNEL CHANGES:
added all TKG patches except the iommu grouping patch (this patch is no longer needed and causes more problems than it fixes):
