Ssh
好：出錯並退出
我正在開發執行 Raspbian GNU/Linux 10 (buster) 的 Raspberry Pi Zero W。其他 X11 應用程序，如
xlogo、xclock、xosview，甚至xeyes執行得很好，但我沒有運氣執行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我在本地網路中通過 SSH 訪問 Pi 並使用 X11 轉發。
任何想法？

當您通過 ssh 從 Mac 登錄到 Pi 時，客戶端程序 (oneko) 在 Pi 上執行，並聯繫在 Mac 上執行的 X 伺服器。
我只是通過從我的 MacBook 登錄到我的 Debian PC 來嘗試這個
ssh，並且oneko執行良好，當我這樣做時xdpyinfo，我看到的擴展數量與我xdpyinfo直接在我的 Mac 上看到的相同。但是，在您的情況下，轉發的連接完全不同：
number of extensions: 2 BIG-REQUESTS XC-MISC這是很少擴展的方式，特別是沒有形狀。所以現在的問題是為什麼會發生這種情況。
我看到您有兩個 X 轉發登錄（sshd 在 6010 和 6011 上都監聽）。當您只使用一次登錄時會發生什麼？
編輯
要將評論的結果添加到答案中：有必要使用 ssh 和受信任的轉發（即
ssh -Y，而不是ssh -X）以使所有擴展都可用。
