不使用ccsm的多个工作区壁纸

Question

不使用CCSM，每个工作区有什么不同的背景吗？我读过一些恐怖故事，如果可能的话，我宁愿避免。我用的是拉响环尾(13.04)

Answer 1

在不同的工作区上有不同的壁纸而不使用ccsm

下面的脚本不使用compiz设置管理器，但它假设：

• 安装了python3 (如果不通知我的话)
• 安装了wmctrl (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壁纸。

脚本启动后，只需切换到不同的工作区，并以“普通”(GUI)方式设置壁纸即可。脚本在创建的小文件中跟踪每个工作区的壁纸(S)。这不应导致性能上的任何滞后，因为只有在脚本启动时，或者当用户更改每个工作区的壁纸时，才会读取文件。

脚本

#!/usr/bin/env python3

import subprocess
import time
import os

key1 = "gsettings set org.gnome.desktop.background picture-uri "
key2 = "gsettings get org.gnome.desktop.background picture-uri"

def write_wspaces(file, current):
    with open(file, "wt") as wt:
        wt.write(current)

def read_wspaces(file):
    with open(file) as src:
        return src.read().strip()

def get_info(command):
    return subprocess.check_output(["/bin/bash", "-c", command]).decode("utf-8")

def get_currwallpaper():
    return get_info(key2).replace("file://", "").strip()

# get resolution
output = get_info("xrandr").split(); idf = output.index("current")
res = (int(output[idf+1]), int(output[idf+3].replace(",", "")))

def calculate_geometry():
    # get viewport data
    vp = get_info("wmctrl -d").split(" ")
    span = vp[4].split("x"), vp[7].split(",")
    # calculate number of (horizontal) viewports
    n_vps_hor = int(int(span[0][0])/int(res[0]))
    n_vps_vert = int(int(span[0][2])/int(res[1]))
    n_wspaces = int(n_vps_hor)*int(n_vps_vert)
    # calculate current viewport
    curr_vp_hor = int((int(span[1][0])/int(res[0]))+1)
    curr_vp_vert = int((int(span[1][3])/int(res[1]))+1)
    return ((curr_vp_vert-1)*n_vps_hor)+curr_vp_hor, n_wspaces

home = os.environ["HOME"]
wspaces = home+"/"+".config/wall_wspaces"
if not os.path.exists(wspaces):
    os.makedirs(wspaces)
if not os.path.exists(wspaces+"/wspaces.txt"):
    current = get_currwallpaper().replace("'", "")
    writelist = []; [writelist.append(current) for i in range(calculate_geometry()[1])]
    write_wspaces(wspaces+"/wspaces.txt", str(writelist))
wall_list = eval(read_wspaces(wspaces+"/wspaces.txt"))

while True:
    curr_vp1 = calculate_geometry()[0]; currwallpaper1 = get_currwallpaper()
    time.sleep(2)
    curr_vp2 = calculate_geometry()[0]; currwallpaper2 = get_currwallpaper()
    if curr_vp1 != curr_vp2:
        command = key1+"file://"+str(wall_list[curr_vp2-1])
        subprocess.Popen(["/bin/bash", "-c", command])
    elif currwallpaper1 != currwallpaper2:
        wall_list = eval(read_wspaces(wspaces+"/wspaces.txt"))
        wall_list[int(curr_vp2)-1] = currwallpaper2
        write_wspaces(wspaces+"/wspaces.txt", str(wall_list))
    else:
        pass

如何使用

只需将脚本复制到空文件中，将其保存为workspace_walls.py并通过命令运行：

python3 /path/to/workspace_walls.py

如果它按照您的意愿工作，那么将它添加到您的启动应用程序中:破折号>启动应用程序>添加

编辑：

下面是一个完全重写的脚本版本，用于这一个模型。

脚本(有一些细微的差异)+ GUI也可以作为ppa提供：

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

#!/usr/bin/env python3
import subprocess    
import os
import time

workspace_data = os.environ["HOME"]+"/.wallpaper_data_"
key = [
    "gsettings get ",
    "gsettings set ",
    "org.gnome.desktop.background picture-uri",
    ]

def getwall():
    return subprocess.check_output(
        ["/bin/bash", "-c", key[0]+key[2]]
        ).decode("utf-8").strip()

def get_res():
    # get resolution
    xr = subprocess.check_output(["xrandr"]).decode("utf-8").split()
    pos = xr.index("current")
    return [int(xr[pos+1]), int(xr[pos+3].replace(",", "") )]

def current():
    # get the current viewport
    res = get_res()
    vp_data = subprocess.check_output(
        ["wmctrl", "-d"]
        ).decode("utf-8").split()
    dt = [int(n) for n in vp_data[3].split("x")]
    cols = int(dt[0]/res[0])
    curr_vpdata = [int(n) for n in vp_data[5].split(",")]
    curr_col = int(curr_vpdata[0]/res[0])+1
    curr_row = int(curr_vpdata[1]/res[1])
    return str(curr_col+curr_row*cols)

curr_ws1 = current()
currwall1 = getwall()

while True:
    time.sleep(1)
    currwall2 = getwall()
    # print(currwall2)
    curr_ws2 = current()
    datafile = workspace_data+curr_ws2
    if curr_ws2 == curr_ws1:
        if currwall2 != currwall1:
            open(datafile, "wt").write(currwall2)
    else:
        if not os.path.exists(datafile):
            open(datafile, "wt").write(currwall2)
        else:
            curr_set = open(datafile).read()
            command = key[1]+key[2]+' "'+str(curr_set)+'"'
            subprocess.Popen(["/bin/bash", "-c", command])
    curr_ws1 = curr_ws2
    currwall1 = getwall()

Budgie现在支持

当从ppa安装时，在2017年7月21日增加了对Budgie的支持(见上文)
