rc.local 和 xrandr 不能一起工作

tag-icon • tag-icon bash brightness xrandr
rc.local 和 xrandr 不能一起工作

所以我在啟動時遇到了螢幕亮度的問題。

這很不幸，因為我嘗試了很多方法來將其設置為正確的設置，但當我調用此命令時，只有 xrandr 為我工作。

xrandr --output eDP --brightness 1

在我的 Ubuntu 上，我沒有/etc/rc.local文件 - 所以我創建了它並使其可執行。

~ » ls -laht /etc | grep rc.local
-rwxr-xr-x   1 root root    342 lis 29 19:26 rc.local

文件的內容是

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

xrandr --output eDP --brightness 1

exit 0

當我重新啟動系統時，我得到失敗狀態rc-local.service

我做錯了什麼？

編輯1：當我將其放入啟動時它也不起作用。 啟動配置
