How should a Gnome applet store its configuration data?

流过昼夜 提交于 2020-01-12 21:24:08
问题 I have a Gnome applet written in Python. In order to save configuration data/settings, it creates a file ~/.appname . However, this prevents multiple instances of the applet from being added to the panel because each cannot have its own settings. How can I store the settings in a way that allows each instance to have its own unique settings? Update: I specifically want to know how to store settings per instance . 回答1: The recommend way for an applet would be to use GConf to store preferences

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 你可以在 这里 找到本文的原文。 从Oracle Linux 7和Red Hat Linux 7开始,默认的桌面环境变成了Gnome3。与之前的Gnome相比,Gnome3带来了很多新的东西,但是也带来很多新的问题。比如UI的不稳定,一些应用程序不支持。 还好,Linux的世界从来不会因为一个软件的更新而困住用户,对于Linux的桌面环境来说,我们还可以选择KDE或者更轻量级的XFCE。 环境说明 本文使用了Oracle Linux 7.2和SGD 5.2。 XFCE的安装 由于Oracle Linux和Red Hat Linux官方不提供XFCE的安装包,所以需要从EPEL进行安装。 下载EPEL的rpm文件 http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm 通过Yum来安装EPEL yum install --nogpgcheck epel-release-7-8.noarch.rpm 安装XFCE桌面环境 yum -y group install "Xfce" 在SGD管理控制台中配置XFCE桌面对象 打开 SGD Administration Console , 创建一个应用程序对象,命名为 Xfce

CentOS 安装图形界面 Gnome

文章目录 1,安装图形用户接口X Window System 2,安装图形用界面gnome 3,设置centos系统默认的启动方式 4,重启系统即可。 1,安装图形用户接口X Window System yum groupinstall "X Window System" 提示: X Window System本身是一个非常复杂的图形化作业环境,我们可以将它分成3个部分,分别是X Server、X Client和X Protocol。X Server主要是处理输入输出的信息,X Client执行大部分应用程序的运算功能,X Protocol则是建立X Server和X Client的沟通管道。 X Window通过软件工具及架构协议来建立操作系统所用的图形用户界面,此后则逐渐扩展适用到各形各色的其他操作系统上,几乎所有的操作系统都能支持与使用X Window,GNOME和KDE也都是以X Window为基础建构成的。 2,安装图形用界面gnome yum groupinstall "GNOME Desktop" 提示:检查已经安装的软件以及可以安装的软件,用命令yum grouplist 3,设置centos系统默认的启动方式 同样在root用户权限下,设置centos系统默认的启动方式,输入命令如下: systemctl set-default multi-user.target

Ubuntu各个版本的介绍 Ubuntu的版本比较多,而且基于ubuntu的衍生版也很多,让人容易混淆,也让很多人不知道自己适合哪一个,在这里简单比较一下ubuntu的各个版本的特点:   介绍ubuntu版本之前先说一说与ubuntu有关的一些知识:   Ubuntu的版本号命名规则:   ubuntu的版本命名规则非常简单易记:   前两位数字为发行时的年份年份的最后两位数字,后两位为发行的月份,中间以一个英文小数点隔开。   例如现在ubuntu的最新版是10.10,则代表了是在2010年10月份发行的。   上一个版本是10.04,则代表了是在2010年4月份发行的。   Ubuntu的代号命名   :   Ubuntu的代号名非常有趣可爱,固定是形容词再加上动物名称,而且这个形容词和动物名的英文单词的第一个字母都是相同的。   Ubuntu 4.10 – Warty Warthog (多疣的疣猪)   Ubuntu 5.04 – Hoary Hedgehog (白发的刺猬)   Ubuntu 5.10 – Breezy Badger (活泼的獾)   Ubuntu 6.06 – Dapper Drake (整洁的公鸭)   Ubuntu 6.10 – Edgy Eft (尖利的小蜥蜴)   Ubuntu 7.04 – Feisty Fawn (烦躁不安的小鹿)  

How do I get the username owning the currently active gui session?

蓝咒 提交于 2020-01-06 02:24:09
问题 I published some scripts to automatically mount and unmount disks in Linux, and now I got a request to make the disks owned by the currently logged in user. That is, the user currently holding the gui occupied (we don't care about terminal users in this case). How would I go about getting hold of the username? There could be a multitude of different window managers, so different solutions depending on wm might be needed, if no wm-independant solution exists. For a start, a solution just
