I recently installed Ubuntu 18.04 on my ASUS X512D, and I have a problem resuming from sleep mode: the screen is black (with a working pointer) or corrupted and the only thing I can do is manually reboot the computer (and loose my work). Pretty annoying for a laptop..
Computer: AMD Ryzen R5 / AMD Radeon Vega 8 / Dual boot with WIN10 Link for specs: ASUS Zenbook S512DA-EJ162T

What I tried:
- Switching to lightdm, even worse (not even the pointer on screen) so I got back to gdm3
- Updating kernel (I tried several ones, now I run the lastest mainline one, 5.2.5)
- A lot of things from forums and other AskUbuntu posts
I also went to Software update > additional drivers and it doesn't show any proprietary driver
Another element, I had to reinstall Ubuntu because on the first try the GPU was not recognized and Ubuntu said in the settings Unknown screen. I guess buying a computer with an AMD proc was not such a good idea to use it with Ubuntu..
Thank you to anyone who'd try helping me!
