Worked fine on 16.04. Status in linux package in Ubuntu: New Bug description: Title of my display under Settings is "Unknown Display". I think there's no proper display driver for my laptop in this new distribution, "18.04", because the setting for my display works fine before I upgrade from 16.04. While I said "works fine", I meant, I could use the "fn" button plus with the brightness adjusting button, which is "f5" and "f6" on my laptop, to adjust the brightness. Other than the "fn" combination button not working, I can't even adjust the brightness in the setting and inside the main menu bar, which I think there might have since a control center is one of the features of this version upgrade. So, thanks for reading my problem, and please help, otherwise, it's so unhealthy for my eyes for looking at a screen with too bright for so long and I have to look at the screen for so long. Thanks in advance. Ps, in case it's needed, the model of my laptop is, ASUS T300F. A transform 2-in-one laptop. The fact that my laptop can "transform" might be the reason why I got this issue, the drive that serves all just fail to meet its needs. I'm sorry.
