use*_*340 4 wallpaper unity workspaces ccsm budgie
有没有办法在不使用 CCSM 的情况下为每个工作区设置不同的背景?我读过一些恐怖故事,如果可能的话,我宁愿避免它。我正在使用 Raring Ringtail (13.04)
下面的脚本不使用 compiz 设置管理器,但它假定:
python3 已安装(如果没有让我知道)wmctrl已安装(以获取工作区上的数据)。您可能需要安装它:sudo apt-get install wmctrl无论工作区的数量如何,它都可以工作;它计算工作区的列数和当前工作区的行数,并为该(当前)工作区设置用户定义的墙纸。
脚本启动后,只需切换到不同的工作区并以“正常”(GUI)方式设置壁纸。该脚本在它创建的一个小文件中跟踪每个工作区的墙纸。这不会导致任何性能延迟,因为文件仅在脚本启动时或用户更改每个工作区的壁纸时才会读取。

只需将脚本复制到一个空文件中,将其另存为workspace_walls.py并通过以下命令运行它:
python3 /path/to/workspace_walls.py

如果它如您所愿,请将其添加到您的启动应用程序中:Dash > Startup Applications > Add
下面的脚本的完全重写版,模型这一块。
脚本(有一些细微差别)+ GUI 也可用作ppa:

sudo add-apt-repository ppa:vlijm/wswitcher
sudo apt-get update
sudo apt-get install wswitcher
