Docker运行图形化程序

由 旧城冷巷雨未停 提交于 2019-12-10 11:42:23
　原理 Docker支持图形化程序，是利用Linux的X11技术。 相关文章 如何在Docker容器中启动D-Bus 引文详情 如何在Docker容器中启动D-Bus 翻译自 https://georgik.rocks/how-to-start-d-bus-in-docker-container/ 很多Linux应用需要用到 D-Bus, 但它在Docker容器中默认并不存在 当你尝试启动这类应用时，你会收到一个错误信息: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/lib/dbus/machine-id": No such file or directory See the manual page for dbus-uuidgen to correct this issue. D-Bus not built with -rdynamic so unable to print a backtrace Aborted 首先你需要通过下面命令生成缺失的 machine-id(译者注:我一般是直接在容器启动时挂载host上的machine-id): dbus-uuidgen > /var/lib/dbus/machine-id 这样以来

问题 Im using Ubuntu 12.04. I want to access Rhythymbox using Python . This is how I've proceeded so far: Ive gone through this site https://live.gnome.org/RhythmboxPlugins/WritingGuide , but it gives details on how to write plugins , which Im not interested in right now. Ive gone through a few tutorials which tells me to do this. import dbus session_bus = dbus.SessionBus() proxy_obj = session_bus.get_object( 'org.gnome.Rhythmbox', '/org/gnome/Rhythmbox/Player') But I am getting the following

Simple C or C++ API for controlling systemd services

由 时间秒杀一切 提交于 2019-12-08 16:31:55
问题 Goal I'd like to write C/C++ applications and provide an API for them to communicate directly with systemd -managed services. Effectively, I'd like my applications to be able to do the equivalent of systemctl start service_name@unit_number.service without using system() , popen() , or exec() calls ( hard requirement ). Question Is there a simple C/C++ API for communicating with systemd , assuming systemd version 219 (i.e. CentOS v7.4, also a hard requirement )? Work So Far I've scoured online

How do I register a profile with bluez using dbus/gio?

由 为君一笑 提交于 2019-12-08 11:25:57
问题 I'm trying to register a profile with bluez through D-Bus/Gio. When I call RegisterProfile everything goes OK. I check my GError and it's NULL and my return value is an empty GVariant. I've tried many things, but here is my latest code. When I run it, it prints "g_dbus_connection_call_sync succeeded", but I can't see my new profile in D-Bus using d-feet and I cannot connect to it using a my test device. I know the code on the test device works, or at least did work with straight bluez, but I

How to use dbus-send to call org.bluez.Adapter1.StartDiscovery?

由 淺唱寂寞╮ 提交于 2019-12-08 08:17:51
问题 I am trying to interact with Bluez 5.44 using the dbus-send command line tool. I cannot seem to get it to start discovery properly, although it works fine when I use bluetoothctl 's scan on and scan off commands. I can also start and stop discovery using d-feet . I've tried powering off and on prior to issuing the command, but it doesn't seem to get discovery started. The command line I'm using is: dbus-send --system --type=method_call --print-reply --dest=org.bluez \ /org/bluez/hci0 \ org
