显卡驱动的问题

还是机械革命code01香！

自己手动敲命令调节亮度，最好是写成脚本方便些：

查询当前显示设备

xrandr --current | sed -n 2p | awk '{print $1}'

调节亮度，10为最亮，DEVICE应该改为你的显示设备

xrandr --output DEVICE --brightness .7

显卡驱动版本？内核版本？

稍等，我查一下

显卡驱动版本查不到，内核5.7.7;之前尝试过升级到5.9,还是没法调节亮度

怎么解决呢

同款

到bios里把某个显卡禁了,,只用外置或者内置的显示吧..

之后把内核升了5.8    我之前也是无法调亮度,后来升内核就好了

怎么查的？apt search nvidia看看有没有

看起来没装驱动，sudo apt install xserver-xorg-video-nvidia，装450版本的

报错

按照提示把那两个软件包装了

已经安装了最新版，但是亮度还是无法调节
