gnome-shell 錯誤日誌

我在哪裡可以找到gnome-shell錯誤（或調試）日誌？

我對發出錯誤/警告消息很感興趣，因為我有一個 GLX 問題需要調試，而且我相信關鍵可能在gnome-shell’s 消息中。

我將從 journald 的日誌開始。嘗試其中之一：

$ journalctl /usr/bin/gnome-shell
$ journalctl /usr/bin/gnome-session

如果日誌不存在，請嘗試以下操作：

$ journalctl -xe

Google搜尋我確實找到了這個標題為：gnome-session logging 的文章，當我在我擁有的 Ubuntu 16.04 系統上嘗試它們時，它確實有幾個範例有效。
