当通过终端时

如何通过 VNC 在无头 Oracle 云上运行 Blender GUI？

计算必须是VM.Standard.E2.1.Micro（AMD 处理器）或VM.Standard.A1.Flex（ARM 处理器）。两者都可以在其免费套餐中试用。我正在使用 Ubuntu 22.04 映像。

当通过终端时

它工作没有问题：

> sudo apt-get install -y blender

> blender --version
Color management: using fallback mode for management
Color management: Error could not find role data role.
Blender 3.0.1

> blender test.blend --background --render-frame 1 --render-output '/tmp/out_####' -F PNG --engine CYCLES -noaudio

当通过SSH X11转发时

它工作没有问题，只是速度太慢：

$ ssh -X user@ip_address

> sudo apt-get install -y blender
> blender

启动 Blender 需要整整一分钟，关闭启动窗口需要 10 秒。移动也需要 10 秒。

当通过 VNC 通过反向 SSH 隧道时

$ ssh -L 5901:localhost:5901 user@ip_address

> sudo apt-get install -y blender freeglut3 tightvncserver xfce4
> tightvncserver -nolisten tcp -localhost :1

然后blender通过 VNC GUI 运行：

> blender
Xlib:  extension "XInputExtension" missing on display ":1".
./intern/ghost/intern/GHOST_WindowX11.cpp:136: X11 glXQueryVersion() failed, verify working openGL system!
initial window could not find the GLX extension
Color management: using fallback mode for management
Color management: Error could not find role data role.
Color management: scene view "Filmic" not found, setting default "Standard".

并下载网站上最新版本的 Blender:

> ./blender
