I have a dual boot Ubuntu/W10 on a MSI Bravo Laptop with an AMD CPU and AMD GPU.
Laptop screen only shows an underscore on the upper left corner and the rest is black after I choose to boot with Ubuntu. The only output I get is when I connect an external monitor via HDMI and everything seems to work ok, but settings only detect one display.
I see lots of posts about this with Nvidia cards but only managed to get this and tried Methods 1 and 2 but none of them seem to work.
None of this happens when I boot with Windows 10, but need Ubuntu for work. Any suggestions? Do you need more info or any command output?

After getting an answer here:
I downloaded the drivers from here and followed the instructions. Had to install it with --no-dkms
as I ran into the same problems as this question.
Now the laptop display works, but not the external monitor.

? The first command will show the model of the video card (and other hardware), the second will show information about the connected display devices.
