Panfork GPU Driver

Switching Xorg server​

info

Although the official image comes with a vendor Mali driver, it only supports OpenGL ES, which is not compatible with the OpenGL interface used by most applications in the Linux ecosystem. The Panfork open source driver needs to run on the mainline Xorg server, and the vendor Mali driver needs to run on the Rockchip Xorg server. So we need the following command to switch the Xorg server version.

sudo apt update
sudo apt-get install xserver-xorg-core/bullseye

#  To restore the Rockchip Xorg server, run the following command
#  sudo apt-get install  xserver-xorg-core/rockchip-bullseye

Setting the priority of Panfork dependencies​

echo /opt/panfrost/lib/aarch64-linux-gnu | sudo tee /etc/ld.so.conf.d/0-panfrost.conf
sudo mv /etc/ld.so.conf.d/00-aarch64-mali.conf /etc/ld.so.conf.d/2-aarch64-mali.conf
sudo ldconfig

test effect​

1.Restart Window Manager​

systemctl restart sddm.service

2.Login Desktop​

3.Open the virtual terminal corresponding to the desktop environment and run the following command​

info

The driver runs better under Wayland, use apt to install plasma-workspace-wayland and select the corresponding session in the SDDM login screen.

sudo apt update
sudo apt install glmark-x11  # Install glmark-wayland if your desktop is running in a Wayland environment.
