我无法让 Jessie 使用 Celeron N3050 (Braswell) 上的集成显卡。
我尝试从 jessie-backports 安装 xserver-xorg-video-intel，但这没有帮助。

我遇到的根本问题是xrandr无法识别伽玛，因此无法设置输出设备参数（我主要感兴趣的是亮度）。
答案1
我自己刚刚遇到了这个问题（同样的问题，类似的硬件和你在此处引用的输出），我努力进行各种调整和 Xorg 配置，但没有运气，直到我发现唯一对我有用的修复方法是将我的内核从 3.16 更新通过 Jessie 向后移植到 4.9：
sudo apt-get -t jessie-backports install linux-image-4.9.0-0.bpo.2-amd64
在我的故障排除中，从 glxgears 返回了与中发现的相同的错误这个SE问题，我尝试了中建议的库第二名该解决方案仅修复了 3D 图形错误，但为了完全控制显示并将功能返回到 xrandr、xbacklight 等，内核升级是必要的。显示/背光相关的东西从那里开始工作，包括背光媒体键。
