	cd /usr/lib
	sudo wget https://github.com/JeffyCN/mirrors/raw/libmali/lib/aarch64-linux-gnu/libmali-valhall-g610-g6p0-x11-wayland-gbm.so -O libmali-g610.so

utilizzata anche funziona ???

	sudo wget https://github.com/JeffyCN/mirrors/raw/libmali/lib/aarch64-linux-gnu/libmali-valhall-g610-g24p0-x11-wayland-gbm.so -O libmali-g610.so

Ensure Firmware File Exists

	su
	cd /lib/firmware
	ls mali_csffw.bin

if not exit

	sudo wget https://github.com/JeffyCN/mirrors/raw/libmali/firmware/g610/mali_csffw.bin

exit form su

	exit

Configuring OpenCL ICD Loader: Install Mesa OpenCL ICD, Create OpenCL Vendors Directory and Add Mali ICD Configuratio

	sudo apt update
	sudo apt install mesa-opencl-icd -y
	sudo mkdir -p /etc/OpenCL/vendors
	echo "/usr/lib/libmali-g610.so" | sudo tee /etc/OpenCL/vendors/mali.icd

Installing OpenCL Libraries and their dependencies

	sudo apt install ocl-icd-opencl-dev -y
	sudo apt install libxcb-dri2-0 libxcb-dri3-0 libwayland-client0 libwayland-server0 libx11-xcb1 -y

Verifying Installation with clinfo

	sudo apt install clinfo -y
	clinfo

output like 

```bash

## Installare Vulkan

[ref](https://github.com/Bleach665/Mali610Vulkan)
[ref deb file](https://repo.rock-chips.com/edge/debian-release-v2.0.0/pool/main/r/rockchip-mali/)

scaricare ed installare il pacchetto deb

	wget https://repo.rock-chips.com/edge/debian-release-v2.0.0/pool/main/r/rockchip-mali/rockchip-mali_1.9-12_arm64.deb
	sudo dpkg -i rockchip-mali_1.9-12_arm64.deb

fare il link 

	sudo ln -s /usr/lib/aarch64-linux-gnu/libmali-valhall-g610-g6p0-wayland-gbm-vulkan.so /usr/lib/aarch64-linux-gnu/libmali.so

inserire icd Loader

```bash
sudo mkdir -p /etc/vulkan/icd.d/

echo '{
    "file_format_version": "1.0.0",
    "ICD": {
        "library_path": "/usr/lib/aarch64-linux-gnu/libmali-valhall-g610-g6p0-wayland-gbm-vulkan.so",
        "api_version": "1.0.0"
    }
}' | sudo tee /etc/vulkan/icd.d/mali.json
```

installare vulkaninfo per verificare

	sudo apt install vulkan-tools
	vulkaninfo


## Install TigerVNC Server

[ref1](https://guide.debianizzati.org/index.php?title=TigerVNC)
[ref2](https://computingforgeeks.com/install-and-configure-tigervnc-vnc-server-on-debian/)
[ref3](https://www.howtoforge.com/how-to-install-vnc-server-on-debian-12/)

### Installare Tasksel per inserire un ambiente grafico

in questo caso scegliere per esempio xfce

	sudo apt install tasksel
	sudo tasksel

se tasksel non finisce l'installazione chiudere il terminale e riaprirlo poi digitare

	sudo apt --fix-broken install

per riparare e digitare sempre Y

sarebbe meglio utilizzare

	sudo apt install xfce4 xfce4-goodies
	sudo apt install lightdm

#### Auto-login xfce4
	
	sudo nano /etc/lightdm/lightdm.conf

nella sezione

```
[Seat:*]
```

inserire

	autologin-user=orangepi

#### Disabilitare start di xfce4 al boot
 
	sudo systemctl disable lightdm.service

#### Start xfce4 manuale 

	sudo systemctl start lightdm.service

### Installare tigervnc

	sudo apt install tigervnc-standalone-server tigervnc-common
	sudo apt install tigervnc-tools

verificare quali sono i desktop disponibili

	ls -hl /usr/share/xsessions/*
	
in questo caso avendo appena installato xfce ci sarà un file xfce.desktop	

far partire per esempio con

	tigervncserver -rfbport 5901 -localhost no -geometry 1280x720 -depth 32 -desktop Prova -- xfce 

oppure

		tigervncserver -rfbport 5901 -localhost no -- xfce -geometry 1280x720 --depth 32 -desktop Prova -autokill no

se si vuole fare una configurazione in automatico senza scrivere tutto

killare la sessieno appena lanciata

	tigervncserver -kill :1

inserire la configurazione di VNC editando

	sudo nano .config/tigervnc/config

il vecchio riferimento era

	sudo nano ~/.vnc/config


va inserito

```bash
rfbport=5901
localhost=no
session=xfce
geometry=2560x1440
depth=32
desktop=Prova
```

facendo partire tigervnc con

	tigervncserver
	
avremo il server su IP:5091

la lista è disponibile udando

	tigervncserver -list

se ne può creare più di uno e si può fermare killandolo

	tigervncserver -kill :1

definire uno user editando 

	sudo nano /etc/tigervnc/vncserver.users

se si vuole farlo partire in automatico va inserito il display e lo user che non sia root per es 

	:1=orangepi

poi si fa partire il servizio 

	sudo systemctl start tigervncserver@:1.service

che si può controllare con

	sudo systemctl status tigervncserver@:1.service

infine lo si abilita per quando il sistema reboota
	
	sudo systemctl enable tigervncserver@:1.service
	
pèer tutte le funzioni digitare

	tigervncserver -help


per esempio se si vuole fare tutto in manuale si può digitare

	tigervncserver -rfbport 5901 -localhost no -geometry 1280x720 -depth 32 -desktop Prova -- xfce
