Chrome和Chromium需要很长时间才能加载

我使用的是Ubuntu 16.04.2，今天，Google Chrome和Chromium开始加载需要很长时间。打开后，它们经常冻结。

我从命令行加载了Chrome，并收到了以下消息：

$ google-chrome
Gkr-Message: secret service operation failed: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
[8032:8100:0504/165233.258127:ERROR:connection.cc(1954)] Cookie sqlite error 5, errno 0: database is locked, sql: DELETE FROM cookies WHERE persistent != 1

从命令行加载铬会返回以下内容：

$ chromium-browser
Gkr-Message: secret service operation failed: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
Killed

我已经完全删除了chrome / chromium，删除了.config和.cache中各自的文件夹

我怎样才能解决这个问题？

通过创建~/.config/autostart/gnome-keyring-daemon.desktop具有以下内容的文件来解决此问题：

[Desktop Entry]
Type=Application
Exec=/usr/bin/gnome-keyring-daemon
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name[en_US]=Gnome Keyring Daemon
Name=Gnome Keyring Daemon
Comment[en_US]=Load gnome keyring daemon
Comment=Load gnome keyring daemon

然后，我重新启动，Chrome / Chromium恢复到正常（源）。

重新启动后，我不断收到此消息“登录时未解锁密钥”，必须输入密码。我遵循以下说明摆脱了它：如何停止提示我在引导时解锁“默认”钥匙圈？
