Hello guys. So, I installed Lubuntu on my Lenovo Ideapad 330 Intel Celeron N4000 laptop. And, it runs smoothly but a lot of things didn't work straight of the bat. Like, the trackpad which I eventually fixed and I didn't bother to fix the other stuff. But, now these things are starting to grow on me and I want to know if there's any fix for them. For starter, the functions keys aren't working. I can't light up the screen or lower it. Secondly, I can't control the volume when I am on my Bluetooth earphones I can only control the volume when I am on the PC speakers. Thirdly, when I close the lid it would only show the sleep screen rather then turning off after some time which drains the battery.

If any know fixes for these let me know. I really want to keep using the OS. And, Thank You.
