lxc nvidia错误：xf86EnableIOPorts：无法为I / O设置IOPL（不允许操作）
在尝试让lxc容器（主机16.04，lxc 14.04）共享nvidia的过程中，我在容器中启动X时遇到此错误：
startx – vt8
我收到以下错误：
xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) 我也在/var/log/Xorg.0.log中收到以下警告：
(WW) NVIDIA(0): Unable to get display device for DPI computation.
任何帮助将不胜感激。 到目前为止，我还没有能够使用16.04主机的lxc和nvidia图形。 使用14.04容器我无法使用16.04容器启动图形我无法使键盘/鼠标工作。
我有同样的问题，所以这是解决方案。 键盘/鼠标在ubuntu 16.04 LXC容器内不起作用的原因是xserver-xorg-input-kbd包被删除了，所以如果你使用像
... Driver "kbd" ... Driver "mouse" ...
在容器的xorg配置中 – 它不适用于ubuntu 16.04。
相反，您应该使用evdev配置xorg输入。 由于配置文件中的event*条目的确切数量（例如/usr/share/X11/xorg.conf.d/10-lxc-input.conf ）将取决于容器的/dev/input/ ，可以使用脚本生成一个：
#!/bin/bash cat >/usr/share/X11/xorg.conf.d/10-lxc-input.conf << _EOF_ Section "ServerFlags" Option "AutoAddDevices" "False" EndSection _EOF_ cd /dev/input for input in event* do cat >> /usr/share/X11/xorg.conf.d/10-lxc-input.conf <<_eof_ Section "InputDevice" Identifier "$input" Option "Device" "/dev/input/$input" Option "AutoServerLayout" "true" Driver "evdev" EndSection _EOF_ done
其结果如下： cat /usr/share/X11/xorg.conf.d/10-lxc-input.conf
