Deepin15.11用下来都挺好,可以满足日常办公需求,可是就是 无法调节笔记本电脑屏幕亮度,亮瞎眼了,也按照网上的一些经验尝试换显卡驱动和内核,可惜对我都失败了,不知道是我的操作方法有问题还是有其他问题,请大家想想办法帮我解决一下,多谢了!PS:电脑是Lenovo的Yoga710-14,显卡是intel集显加N卡940mx

看一下 目录/sys/class/backlight/
亮度调节可以参考
Backlight - ArchWiki -
https://wiki.archlinux.org/index.php/Backlight
也可能与nvidia的驱动有关 ,安装nvidia 显卡驱动
参考(双显卡)
https://bbs.deepin.org/post/178542
添加backports源
deb [trusted=yes]
https://mirrors.ustc.edu.cn/debian/
stretch-backports main contrib non-free
安装backports驱动
sudo apt update -y && sudo apt-get install -t stretch-backports nvidia-driver

文档中的方法都是过了,没有效果,也可能是我不会弄,不过感觉教程不是针对Deepin 15.11的才会没有效果。
