Hi @here,

as you maybe noticed, we have rolled out the new NVIDIA Driver, which includes the explicit sync protocol and tearing for Vulkan.
We have been prioritized to move this forward to finally resolve the wayland situation. Additionally arch has pushed CUDA to 12.5, which is NOT compatible with the current 550 driver (it needs the 555 Driver).

The beta driver is not perfect, but so far we are applying some fixes to avoid issues and restore performance problems with disabling the GSP Firmware load. This is handled via the “cachyos-settings” package.

Anyways, since some people maybe have problems with this driver, here is a short instruction to manually downgrade and block the driver:

sudo pacman -U https://archive.cachyos.org/archive/cachyos/nvidia-utils-550.78-5-x86_64.pkg.tar.zst https://archive.cachyos.org/archive/cachyos/lib32-nvidia-utils-550.78-2-x86_64.pkg.tar.zst https://archive.cachyos.org/archive/cachyos/opencl-nvidia-550.78-5-x86_64.pkg.tar.zst https://archive.cachyos.org/archive/cachyos/lib32-opencl-nvidia-550.78-2-x86_64.pkg.tar.zst https://archive.cachyos.org/archive/cachyos/nvidia-dkms-550.78-5-x86_64.pkg.tar.zst

After that you add the NVIDIA Driver to the IgnorePkg function in the pacman.conf:
sudo micro /etc/pacman.conf

IgnorePkg = nvidia-utils opencl-nvidia nvidia-dkms lib32-nvidia-utils lib32-nvidia-utils lib32-opencl-nvidia

If you are facing issues with the new NVIDIA Driver, reproduce the issues and then run “sudo nvidia-bugreport.sh” and report it to their forum:

We are also shipping now an precompiled nvidia-open module. This will be also as default installed for users, which have supported cards as soon NVIDIA releases the 560 drivers.

Congrats for integrating these drivers so quickly! I love Cachy but I have constant freeze problems with Nvidia drivers series 55x. I am not alone and Nvidia forum is full of feedback. It affects Arch-based system, laptops with hybrid graphics (mine is a Lenovo Legion Slim 7 with AMD 780m and Nvidia 4060). I would like to downgrade drivers to series 535 or 545, using X11. How can I do that ?

There is a package called nvidia-535xx-dkms nvidia-535xx-utils nvidia-535xx-settings nvidia-535xx-dkms opencl-nvidia-535xx

I uninstalled Nvidia 555 and installed 535 (with X11 not wayland). It is very stable after several hours. No freeze. I can switch from Steam to file manager, to package installer or other app without any hiccup. Resume from stand-by is a bit hit or miss though. Power off is fine. Benchmarks from Shadow of the Tomb Raider (DX 12) or Cyberpunk show no real difference with 555 and wayland.
Glad it works but sad to see that despite promises from Nvidia, 555 and wayland is far from being stable for all of us…
