我遇到了一些错误，希望有人可以帮助调试。第一和第二是什么意思，如果可能的话，我研究进一步调试步骤和完整解决方案的途径是什么。

运行带有 1950x Threadripper CPU 和 Nvidia 1070 以及最新驱动程序的 Aorus Gaming 7 主板。

我在 Kubuntu 16.04 上使用了一段时间的 Kmail，但由于一些我不喜欢的事情而不得不停止使用它，所以我切换到了 Thunderbird。现在我不想再使用 Kmail 我还想禁用它的通知并阻止它在后台运行。

有什么简单的方法可以在不卸载的情况下做到这一点？我这么说是因为他们可能会解决一些让我想再次使用它的问题。

谢谢

我在 Wireshark 中遇到了 USB 监控问题。除了过去的工作方式之外，wireshark（甚至看不到端口，除非 root）现在显示它可以监控的 USB 端口，但是一旦您单击其中一个端口，它就不允许您实际监控任何流量。

它说权限被拒绝确保您拥有正确的权限。

安装程序时，它建议我不要以 root 身份运行程序，而是将 wireshark 组添加到我的用户帐户中。

我这样做了，但仍然没有工作。我看过几个回答密切相关但不相同的问题。

我认为 16.04 中的某些内容与以前的版本相比有所改变，或者我遗漏了一些东西。

那么我怎样才能让它工作呢？

只是补充一下，我尝试过 - Wireshark - 允许非 root 用户嗅探 USB 流量

它没有帮助。

目前我正在尝试使用 KDevelop 4.7.3 创建一个全新的项目。我也瞄准Qt5。当我尝试使用 Qt Gui 项目的模板创建一个新项目时，它会创建一个 Qt4 项目，然后我将 cmake 文件更改为 Qt5，但是在 Qt4 或 Qt5 状态下，它都找不到要执行的库头文件语义分析，甚至编译。

只是好奇如何解决这个问题。我在 Kubuntu 上安装了 Qt Creator（工作正常）和 KDevelop，所以我假设我已经拥有所需的库，但如果我遗漏了什么，请告诉我。

下面是它自动创建的 make 文件，我添加了一些内容。请根据需要进行编辑。

cmake_minimum_required(VERSION 2.8)
project(stickykey)
find_package(Qt5Core)

find_package(Qt5 REQUIRED Gui Widgets)
find_package(Qt5Widgets)

# # The Qt5Widgets_INCLUDES also includes the include directories for
#   # dependencies QtCore and QtGui
  include_directories(${Qt5Widgets_INCLUDES})
# 
#   # We need add -DQT_WIDGETS_LIB when using QtWidgets in Qt 5.
  add_definitions(${Qt5Widgets_DEFINITIONS})
# 
#   # Executables fail to build with Qt 5 in the default configuration
#   # without -fPIE. We add that here.
#   set(CMAKE_CXX_FLAGS "${Qt5Widgets_EXECUTABLE_COMPILE_FLAGS}")

include_directories(${QT_INCLUDES} ${CMAKE_CURRENT_BINARY_DIR})

set(StickyKey_SRCS StickyKey.cpp main.cpp)

#qt5_automoc(${StickyKey_SRCS})
add_executable(stickykey ${StickyKey_SRCS})
target_link_libraries(stickykey ${QT_QTCORE_LIBRARY} ${QT_QTGUI_LIBRARY} Qt5::Widgets)

我有这个坞站 - （CROSSION Super Speed USB 3.0 Universal Docking Station）http://amzn.to/1UwZ3rO，我正在尝试让以太网端口工作。

我相信它使用的是 Realtek RTL8153 芯片组。我对此不是 100% 确定的，因为我只是从产品随附的磁盘中获取此信息。它有一个标有 RTL8153 的文件夹。

我试图找到制造商的网站，但无法找到更深入的驱动程序。亚马逊页面称该设备支持 Linux。

我正在运行 16.04 并且我正在尝试挂载一个 img 文件，但我没有选择这样做。

如何添加挂载功能？最好是基于 gui 的东西，或者只是一个上下文菜单选项，或者类似的东西会很好，所以它会显示在左侧的 dolphin 中。

谢谢

是否可以隐藏 konsole 标签栏？如果有怎么办。我查看了配置文件选项面板中的设置，但没有任何反应。是否存在命令行设置，或者配置文件修改对此有帮助？我使用 tmux，所以标签对我来说真的没用。

当我通过 USB 插入我的 xbox one 控制器时，它使我的系统崩溃。插入控制器后不久整个系统就锁定了。我必须按下电源按钮才能使系统正常工作。

我应该补充一点，我不是想玩游戏或任何东西。我只想能够插入设备并在其上使用 libusb。

我真的不知道还能说什么。我尝试了每个端口，得到了相同的结果。如果您需要更多信息，请告诉我。

14.04.3 - 3.19.0-37-通用

更新：安装的新内核仍然来自 repos 的相同错误 4.2.0-19-generic

系统日志，经过几次尝试，我的电脑锁定了，我得到了这个。

Nvidia Prime 和图形切换对我来说坏了。

我可以很好地使用我的英特尔显卡，但如果我尝试切换到 Nvidia，它只会显示黑色 lightdm 屏幕。我知道它启动了，因为我能听到迎宾声。

我在切换之前尝试更改分辨率，但仍然是黑屏。

有什么想法可以使它正常工作吗？

我只是想诚实地使用 CUDA，如果我可以使用 CUDA 就不需要切换。

./devicequery 在英特尔图形模式下不返回任何内容，所以我想我必须进入 Nvidia 图形模式。

在 CUDA 7.5 中使用 352

我在 ubuntu 14.04 中使用 kde:plasma 版本 4.13.3，它在大多数方面都运行良好，但在我的笔记本电脑上，我经常将它用作我的“媒体中心”pc。我通过 HDMI 端口将它连接到电视。当我这样做时，一切都很好。Netflix、VLC、桌面声音、视频群聊等的声音……但在我断开 HDMI 电缆后，我再也听不到来自 Netflix、YouTube 或任何其他基于浏览器的音频的声音。我在 Firefox 和 Google Chrome 中对此进行了测试。

我猜这是通过某种方式单独控制的。感谢帮助。
