rk3288 怎么在4.4以上的内核上把vga 显示打开
rk3288 怎么在4.4以上的内核上把vga 显示打开 ，firefly 下载的4.4.77 内核只有hdmi 有显示xrandr 也只能找到hdmi ，论坛上下载了个 ubuntu 16.04 vga 和hdmi 都有显示， 请问下 有没有人知道 怎么配置 内核 和设备数 。老版本内核 移植 这个驱动 是可以的 vga-connector.c vga-encoder.c 我在4.4上移植成功了。 问下 ubuntu 16.04 vga 和hdmi 都有显示的固件还有吗？能否分享下？ linux 内核配置：diff --git a/arch/arm/boot/dts/rk3288-firefly.dtsi b/arch/arm/boot/dts/rk3288-firefly.dtsi
