如何通过远程shell更改Gsettings?

Modified on: Mon, 25 Jun 2018 02:08:23 +0800

我需要通过Puppet,虚拟终端或ssh自动化桌面配置。

不幸的是,通过ssh或虚拟终端调用gsettings会产生:

gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ hsize "4"

(process:29520): dconf-WARNING **: failed to commit changes to dconf: Cannot autolaunch D-Bus without X11 $DISPLAY

当我使用$DISPLAY设置export DISPLAY=:0.0时,会出现另一个错误:

(process:29862): dconf-WARNING **: failed to commit changes to dconf: Could not connect: Connection refused

我该怎么办?

最佳答案

关键是设置DBUS_SESSION_BUS_ADDRESS环境变量。

此主题上,我找到了以下脚本,这有助于获取该变量的正确值。它需要在桌面上运行的进程名称,我们要在其上更改dbus设置。 (可以并行运行多个图形会话)。让我们称之为discover_session_bus_address.sh

#!/bin/bash # Remember to run this script using the command "source ./filename.sh" # Search these processes for the session variable # (they are run as the current user and have the DBUS session variable set) compatiblePrograms=( nautilus kdeinit kded4 pulseaudio trackerd ) # Attempt to get a program pid for index in ${compatiblePrograms[@]}; do PID=$(pidof -s ${index}) if [[ "${PID}" != "" ]]; then break fi done if [[ "${PID}" == "" ]]; then echo "Could not detect active login session" return 1 fi QUERY_ENVIRON="$(tr '\0' '\n' < /proc/${PID}/environ | grep "DBUS_SESSION_BUS_ADDRESS" | cut -d "=" -f 2-)" if [[ "${QUERY_ENVIRON}" != "" ]]; then export DBUS_SESSION_BUS_ADDRESS="${QUERY_ENVIRON}" echo "Connected to session:" echo "DBUS_SESSION_BUS_ADDRESS=${DBUS_SESSION_BUS_ADDRESS}" else echo "Could not find dbus session ID in user environment." return 1 fi return 0

使用此脚本,我们可以执行以下操作,假设桌面上正在运行unity进程,我们要在其上应用我们的设置:

. ./discover_session_bus_address.sh unity gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ hsize "4"

事情应该可行。
