@jr_online 在请问如何用命令行调整背光亮度？中说：

mount -t debugfs none /sys/kernel/debug;
cd /sys/kernel/debug/dispdbg;

#背光0
echo lcd0 > name; echo setbl > command; echo 0 > param; echo 1 > start

#背光255
echo lcd0 > name; echo setbl > command; echo 255 > param; echo 1 > start

添加文件： ~/.asoundrc：

pcm.!default {

        card 0
}

ctl.!default {
        type hw
        card 0
}

搞定了。
