我目前的桌面環境是什麼？

Question

我怎樣才能知道我的桌面環境使用Python？我喜歡的結果是gnome或KDE或其他。

Answer 1

測試在Ubuntu 9.10：

>>> import os 
>>> os.environ.get('DESKTOP_SESSION') 
'gnome' 

編輯：正如在下面的評論中提到，這種方法不適用於多一些操作系統的工作。另外兩個答案提供瞭解決方法。

Answer 2

你可以試試這個：

def detect_desktop_environment(): 
    desktop_environment = 'generic' 
    if os.environ.get('KDE_FULL_SESSION') == 'true': 
     desktop_environment = 'kde' 
    elif os.environ.get('GNOME_DESKTOP_SESSION_ID'): 
     desktop_environment = 'gnome' 
    else: 
     try: 
      info = getoutput('xprop -root _DT_SAVE_MODE') 
      if ' = "xfce4"' in info: 
       desktop_environment = 'xfce' 
     except (OSError, RuntimeError): 
      pass 
    return desktop_environment

人有時候運行桌面環境的混合。使用xdg-utils使您的應用程序與桌面無關;這意味着使用xdg-open打開文件或網址，使用xdg-user-dir DOCUMENTS查找文檔文件夾，xdg-email發送電子郵件等。

我在項目中的一個使用此：

     if sys.platform in ["win32", "cygwin"]: 
      return "windows" 
     elif sys.platform == "darwin": 
      return "mac" 
     else: #Most likely either a POSIX system or something not much common 
      desktop_session = os.environ.get("DESKTOP_SESSION") 
      if desktop_session is not None: #easier to match if we doesn't have to deal with caracter cases 
       desktop_session = desktop_session.lower() 
       if desktop_session in ["gnome","unity", "cinnamon", "mate", "xfce4", "lxde", "fluxbox", 
             "blackbox", "openbox", "icewm", "jwm", "afterstep","trinity", "kde"]: 
        return desktop_session 
       ## Special cases ## 
       # Canonical sets $DESKTOP_SESSION to Lubuntu rather than LXDE if using LXDE. 
       # There is no guarantee that they will not do the same with the other desktop environments. 
       elif "xfce" in desktop_session or desktop_session.startswith("xubuntu"): 
        return "xfce4" 
       elif desktop_session.startswith("ubuntu"):
