Bug 107698

This report is missing a description of the problem in prose.

When I boot ubuntu 18.10 with kernel 4.18rc1-4.18.6 or kernel 4.19rc1 , the result is black screen.

Does amdgpu.dc=0 on the kernel command line avoid the black screen?

Does the screen go black when the amdgpu driver is loaded, or only when the login screen is supposed to start?

I tried to add amdgpu.dc=0 on the kernel command line, but this does not avoid the back screen.
The screen go black when the amdgpu driver is loaded because I can catch to see nothing. I see bootloader only, I choose the kernel version for boot and then back screen.
I don't know what to say but yesterday after I updated/upgraded all the packages , the screen go back if I boot also kernel 4.17.* 
I'll try to reinstall my desktop and I'll be back with my new details. I'm afraid I have an issue at my monitor (It's a TV).

 I reinstalled my desktop but I have the same results. 

I triedamdgpu.dc=0 on the kernel command line but no results, I have black screen.

It's working with kernel 4.17.* but not working with kernel 4.18.* or 4.19.*

Wich new details you need for solving this issue ?

Scuse me for delay but I had a two weeks holliday.

I have installed in my desktop Ubuntu 18.10.
