Two months WPS official wild brush several versions, now Sogou input method can not enter Chinese in the WPS.
Of course, this is my one example, is not a common problem. I tried to install the virtual machine.
Want to fix, I tried everything, ultimately submitted to the WPS official testing.
Today, suddenly found the system "Settings" not open, click no response. Private thought these days toss a bad system?
The first reaction check the system log, and see what the report admit. Also, or the command line to perform it, may also be able to see the error log.
××××××:~$ gnome-control-center
(gnome-control-center:3692): Clutter-WARNING **: 13:26:08.395: Whoever translated default:LTR did so wrongly.
(gnome-control-center:3692): thunderbolt-cc-panel-WARNING **: 13:26:08.598: Could not create client: 为 org.freedesktop.bolt 调用 StartServiceByName 出错： GDBus.Error:org.freedesktop.systemd1.UnitMasked: Unit bolt.service is masked.
段错误
There Error, for a reason. How to solve it? Try to see the situation.
××××××:~$ systemctl start bolt.service
Failed to start bolt.service: Access denied
See system logs and 'systemctl status bolt.service' for details.
××××××:~$ systemctl status bolt.service
● bolt.service
Loaded: masked (/dev/null; bad)
Active: inactive (dead)
Meaning, "Settings" does not open, because "Unit bolt.service is masked". Bolt.service also directly open error.
View bolt.service state, found to be masked state.
So, does that mean changes to unmask like it?
××××××:~$ systemctl unmask bolt
Removed /etc/systemd/system/bolt.service.
××××××:~$ gnome-control-center
Returning to the familiar interface, and she opened the "Settings." In the dock or panel or the upper right corner, but also can open the "Settings" up.
解决后，打开“设置”，第一个页面是thunderbolt，我突然想起来，前几天有过一次打开
设置---thunderbolt，然后设置崩溃的经历。当时并未在意。“设置”会记住最后一次使用的选项，下次打开默认就是最后一次使用的选项。
于是就出现，打不开“设置”的假象。
这么看来，如果清除“设置”的相关配置，应该也一样能打开“设置”，只是仍然不能点击thunderbolt选项。我本机并没有thunderbolt设备。
