[SOLVED]Unable to shutdown my laptop properly

When I use the button from Gnome to shutdown my laptop, the screen goes black directly, and that is all. I have to turn off manually my laptop.
The reboot command in a tty does the same and I tried both the Wayland session or the Xorg session but it does not make any differences.

I don't know how to fix this.

Re: [SOLVED]Unable to shutdown my laptop properly

I'm guessing that you have an AMD gpu which is using the amdgpu kernel driver (verify with some tool like inxi, lspci, glxinfo). In my case I fixed the problem by either using the linux-lts kernel, or by adding the kernel parameter "amdgpu.dc=0" at grub, since I wanted to use the latest kernel.

Re: [SOLVED]Unable to shutdown my laptop properly

If you are with Kernel 4.19.x i'm guessing that it a kernel bug.
The same indication, there is and for me (Intel CPU, Nvidia legacy GPU)... and with poweroff, shutdown, - with all parameters etc...
But with Kernel 4.18.16 all are ok.

Re: [SOLVED]Unable to shutdown my laptop properly

@ThanosApostolou, it works now thanks to the kernel parameter you gave me.

@giannis-arch, yes I guess that it comes with a kernel update because this problem appeared on month ago.

Just keep in mind that amdgpu.dc is usually needed for some functionality like hdmi audio. Maybe we ll have to wait until kernel 4.20 for a fix.
