Hello all,
I have an HP laptop with Intel(R) Celeron(R) CPU N3060 and Intel HD Graphics 400.
I bought this laptop in 2017 and installed FreeBSD 11 on it. I was able to adjust brightness then on this version. The problem was, I was unable to use the onboard WIFI (I solved this problem with using a USB WIFI dongle), and share display with an external device (projector, or monitor). Since I need to make presentations then, I had to remove FreeBSD 11 and used the laptop with Windows 10 until now and continue using FreeBSD on my desktop computer.
I no longer need to make presentations on this laptop. So I decided to install FreeBSD's latest version onto laptop. The main difference on FreeBSD 12.1 is, it now supports onboard WIFI (but bandwidth is very slow). But now, I cannot adjust brightness anymore. I see that a few things changed about driver support.
Here's some output of my system.
/etc/rc.conf includes:
When I
As you can see, lcd0 is inactive.
I updated the laptop's BIOS but no luck. I installed graphics/intel-backlight but it does not work too. FN keys not working but it's not important for me, I can adjust the brightness from console, if may work. I will be very happy, if someone may help me.
Thanks in advance.
Sincerely.
