大多数情况下，我使用win + L锁定计算机，但是长时间使用PC后，无法锁定计算机。
如果我运行cinnamon-screensaver会给我错误：
Cannot acquire session org.freedesktop.DBus client to watch for media players
CsNotificationWatcher: Could not connect to session bus - GDBus.Error:org.freedesktop.DBus.Error.LimitsExceeded: Failed to determine seats of user "1000": Too many open files
Cinnamon Screensaver support not found in current theme - adding some...
Traceback (most recent call last):

GLib.Error: g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.LimitsExceeded: Failed to determine seats of user "1000": Too many open files (8)
我正在使用cinnamon-screensaver 3.6.1。
我该如何解决这个问题？
