在数据中心分配我的系统（Ubuntu 16.04）后，我的 Genymotion 突然因以下错误停止工作：
Logging activities to file: /home/*/.Genymobile/genymotion.log (noting logged here)
Segmentation fault (core dumped)
所以我重新安装了它，但问题仍然存在......所以我通过以下步骤检查了 Virtualbox：
$ sudo /etc/init.d/vboxdrv status
sudo: /etc/init.d/vboxdrv: command not found
所以我想出卸载它们并重新安装。但问题仍然存在
以下是我所做的：
安装Virtualbox及相关软件包：

$ opt/genymotion/genymotion

我发现以下命令与/etc/init.d/vboxdrv setup|status（相同参考）
/sbin/rcvboxdrv setup|status
结果如下：
VirtualBox kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) are loaded
我也尝试解决方案在 KDE 桌面上运行 genymotion 时出现问题但我收到以下错误：
Logging activities to file: /home/*/.Genymobile/genymotion.log (noting logged here)
Aborted (core dumped)
这是 *.log 文件：
Aug 11 01:40:08 [genymotion] [fatal] This application failed to start because it could not find or load the Qt platform plugin "xcb".
Reinstalling the application may fix this problem.
我还检查了 Qt 所需的库，如这里，但结果中未列出，因此所有必要的库都可用。

我寻找该系统已systemd转储核心，/var/lib/systemd/coredump/因此我首先安装coredumpctl，然后运行Genymotion以创建核心转储。按照说明操作这里创建dump.core，结果如下：
$ coredumpctl dump 9808 --output /home/*/genymotion.core

我已经删除了 Genymotion 中的内置 qt，并检查了系统中可用的 qt：
$ qtchooser -list-versions
4
5
default
qt4-x86_64-linux-gnu
qt4
qt5-x86_64-linux-gnu
qt5
但仍然无法启动Genymotion。
qt-unified-linux-x64-3.0.0-online我还通过从以下网址下载安装了 qt-5.9.1这里但是当我运行的时候它没有列出qtchooser -list-versions。（没有可用的新版本），我应该如何强制 Genymotion 与此一起工作？

这个解决方案对我不起作用，我决定重新安装操作系统。现在一切都正常了。但重启系统后，Genymotion 再次失败。
答案1
您的崩溃似乎与Qt 框架（libQt5Gui.so.5）。相关诗句如下：

#0 0x00007f86f96c2428 __GI_raise (libc.so.6)

#10 0x00007f86fa18ebcd _ZN12QApplicationC2ERiPPci (libQt5Widgets.so.5)
搜寻_ZNK14QMessageLogger5fatalEPKcz给出了与该库类似的一些问题。
请查看以下错误：
这表明该问题发生在 Qt 5.5.1-9 中，但不发生在 5.5.1-7（或 -8）中。因此，您可以尝试升级或降级您的 Qt。
/var/lib/sddm/.cache另一个可以尝试的解决方法是按照此方法删除文件评论。
理想情况下，如果你能将你的 Qt 升级到最新可用版本，否则请尝试手动安装（5.9.2 或更高版本）以替换有故障的libQt5Gui.so.5文件库，或者从源代码。
