Xvfb 或 Firefox 抛出错误并无偿记录

根据答案这个问题，我正在运行 Xvfb 来制作虚拟显示，以便 Firefox 将在我的 CentOS 服务器上运行。 （我不需要看到 firefox 或使用 firefox 执行任何实际的键或屏幕输入/输出 - 它只需要运行，以便 Selenium 可以驱动它。）我试图弄清楚为什么 Xvfb （或 firefox）会抛出异常一堆错误。

我使用以下命令启动 Xvfb：

Xvfb :1 -screen 0 1024x768x24 &

在我启动它之后，屏幕上会立即回显一些错误消息（奇怪的是，它们出现在 shell 提示符之后）：

[root@host /home/lm/cron]# Xvfb :1 -screen 0 1024x768x24 &               
[1] 9214
[root@host /home/lm/cron]# expected keysym, got XF86TouchpadOn: line 120 of inet
expected keysym, got XF86TouchpadOff: line 121 of inet

当我运行 Selenium 测试脚本时，Selenium 日志中会出现更多错误：

现在，有趣的部分是，尽管所有这些混乱，一切都正常：Selenium 正在与 firefox 属性对话，firefox 正在做它应该做的事情并将其传递回 Selenium 等等。我只是想知道是否（a）我应该担心所有这些消息/错误，以及 (b) 我该如何清理它？ （实际上在我看来，其中大部分是关于“分配”的某种详细日志信息——我想关闭它——然后那些“预期的键符”消息被抛出异常。）

答案1

我不认为它们有错误。

只是 X 服务器在闲聊。

您也可以通过使用启动 Xvfb 将这些消息发送到 /dev/nullXvfb :1 -screen 0 1024x768x24 2>/dev/null &
