聯想拯救者安裝ubuntu無法連接網絡

原因：聯想網卡驅動與ubuntu驅動衝突，聯想的優先級排在第一且無法硬件開啓，高於ubuntu的優先級
解決方案：

第一：移除聯想的驅動優先級

 sudo modprobe -r ideapad_laptop

第二：解鎖所有驅動

 rfkill unblock all

第三部：加入開機自動執行

#!/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.
echo "root密碼" |sudo modprobe -r ideapad_laptop
exit 0

第四步：root模式下給權限

chmod +x /etc/rc.local

ok了
