我正在开发运行 Raspbian GNU/Linux 10 (buster) 的 Raspberry Pi Zero W。其他 X11 应用程序，如xlogo、xclock、xosview、 甚至xeyes运行得很好，但我运行失败oneko。
pi@nalzoks-pi:~ $ oneko
Display not supported shape extension.
oneko: Error and exit.
BadAccess (attempt to access private resource denied)
pi@nalzoks-pi:~ $ oneko -noshape
oneko: Error and exit.
BadAccess (attempt to access private resource denied)
pi@nalzoks-pi:~ $ sudo oneko
sudo: oneko: command not found
我正在本地网络中通过 SSH 并使用 X11 转发来访问 Pi。
任何想法？

答案1
当您通过 ssh 从 Mac 登录到 Pi 时，客户端程序 (oneko) 在 Pi 上运行，并联系 Mac 上运行的 X 服务器。
我刚刚通过从我的 MacBook 登录我的 Debian PC 进行了尝试ssh，并且oneko运行良好，当我这样做时xdpyinfo，我看到的扩展数量与xdpyinfo直接在 Mac 上看到的扩展数量相同。
但是，在您的情况下，转发的连接截然不同：
number of extensions: 2
BIG-REQUESTS
XC-MISC
这就是很少有扩展的方式，特别是没有 SHAPE。所以现在的问题是为什么会发生这种情况。
我看到您有两个 X 转发登录（sshd 在 6010 和 6011 上监听）。当您仅使用一次登录时会发生什么？
编辑
将评论的结果添加到答案中：有必要使用带有可信转发的 ssh （即ssh -Y代替ssh -X）以使所有扩展可用。
