我正在使用Fedora Workstation 27 gnome-session-3.26.1-1.fc27.x86_64
。
我知道Xwayland仅提供X11应用程序,而本机Wayland应用程序则直接由提供gnome-shell
。我特别想从Xwayland服务器中查找日志消息。
目录~/.local/share/xorg/
为空。我已经尝试过该杂志:
# journalctl -b /usr/bin/Xwayland
-- Logs begin at Fri 2017-04-21 15:22:01 BST, end at Fri 2018-03-23 23:45:13 GMT. --
-- No entries --
# journalctl -b | grep -i 'wayland.*]: '
#
即使第二种方法可以很好地搜索“ gnome-session”,它也没有显示任何内容。
看起来Xwayland是通过与gnome-shell完全相同的套接字连接到日志的。并且,如果您使用查看完整的打开文件列表lsof
,Xwayland没有打开任何日志文件。

gnome-shell
确实从Xwayland
日志连接开始。消息以类似的前缀显示在日志中org.gnome.Shell.desktop[3494]:
,其中3494是gnome-shell进程的PID 。
请参阅“ orgdgnome.Shell.desktop [1711]:”在系统日志中是什么意思?'。
这可能会造成混淆,因为gnome-shell
以相同的方式记录日志,并且可能非常嘈杂。而Xwayland可能非常安静。我看到Xwayland不会记录任何启动消息。我只看到有关错误的日志记录。
您可以尝试使用技巧来查找Xwayland消息
$ journalctl --since=-1month | grep ': [(]..[)] ' | grep -v gdm-x-session
或者
$ journalctl --since=-1month \
| grep -E '[(]([^0-9^a-z]){2}[)]' \
| grep -v gdm-x-session
