====== Vulkan on Wayland ======



[[:VIM3]] [[:VIM3L]] [[:VIM4]] [[:VIM1S]] with Ubuntu 22.04/24.04 Gnome Desktop and Wayland with **5.15** kernel supports Vulkan, you can follow this documentation to test Vulkan.

<WRAP important >
Only for VIM3/3L/4/1S with 5.15 kernel with Ubuntu 22.04/24.04 Gnome Desktop and Wayland.
</WRAP>



===== Install Vulkan tools =====

<tabbox Ubuntu 22.04>

The default ''vulkan-tools'' doesn't support Wayland, so we rebuild it to support Wayland, you can follow the commands below to install ''vulkan-tools''.

```shell
sudo apt update
sudo apt install vulkan-tools
wget https://dl.khadas.com/development/vulkan-tools_1.3.204.0%2Bdfsg1-1_arm64.deb
sudo dpkg -i vulkan-tools_1.3.204.0+dfsg1-1_arm64.deb 
```

<tabbox Ubuntu 24.04>

```shell
sudo apt update
sudo apt install vulkan-tools
```

</tabbox>


===== Check Vulkan informations =====

You can use command ''vulkaninfo'' to get the ''Vulkan'' informations.

```shell
khadas@Khadas:~$ vulkaninfo | less
'DISPLAY' environment variable not set... skipping surface info

===== Run Vulkan cube test program =====

You can run the ''Vulkan'' test program ''vkcube-wayland''.

```shell
$ vkcube-wayland
```

You will see a rotating cube on the screen.
