之前有這篇文章的修改方式：
UBUNTU升級到24.04.2後，本來google remote desktop可以用，變成不能用的可能解法

一樣要再感嘆AI、讚嘆AI。
前幾天apy upgrade把chrome-remote-desktop版本升級後，又把它恢復成官方原始檔案。
再次出現錯誤訊息無法啟用：

上次的改法有點複雜，然後我忘記自己有留文章記錄。
所以再問了一次AI，大概魔法咒語很明確，這次AI回答的方案整個超簡單。
修改這個檔案：
nano /opt/google/chrome-remote-desktop/chrome-remote-desktop
找到這行：
USE_XVFB_ENV_VAR = "CHROME_REMOTE_DESKTOP_USE_XVFB"
然後下面新增這行：
# Start custom modification: Force Xvfb driver to be used
os.environ[USE_XVFB_ENV_VAR] = '1'
# End custom modification
內容改成像這樣：
# This script has a sensible default for the initial and maximum desktop size,
# which can be overridden either on the command-line, or via a comma-separated
# list of sizes in this environment variable.
DEFAULT_SIZES_ENV_VAR = "CHROME_REMOTE_DESKTOP_DEFAULT_DESKTOP_SIZES"
# By default, this script launches Xorg as the virtual X display, using the
# dummy display driver and void input device, unless Xorg+Dummy is deemed
# unsupported.
When this environment variable is set, the script will instead
# launch Xvfb.
USE_XVFB_ENV_VAR = "CHROME_REMOTE_DESKTOP_USE_XVFB"
# Start custom modification: Force Xvfb driver to be used
os.environ[USE_XVFB_ENV_VAR] = '1'
# End custom modification
# If this environment variable is set, the script will launch a Wayland
# session instead of X11.
USE_WAYLAND_ENV_VAR = "CHROME_REMOTE_DESKTOP_USE_WAYLAND"
# ... 程式碼後面部分 ...
修改存檔之後，重新執行一次
sudo systemctl restart chrome-remote-desktop@username.service
應該馬上就會啟動正常了，XDDDD
