This driver issue is not AMD's fault, not entirely anyway. After about 20 reboots did I manage to get my display drivers working on this 1803 Win10 update and now I am still trying to get my motherboard's audio drivers to work and my headset drivers to work. And if that wasn't enough, windows explorer crashes almost every time I have to open an executable that requires to be run as an administrator.
Microsoft is to blame for this sloppy update since even before it was released articles were popping up about how it got delayed due to "issues". I guess they still didn't fix all of them...
You can install the new driver available here : Radeon Software Adrenalin Edition Q2 2018 Release Notes
Note : It is essential that you reboot the system after you install these drivers.
Please submit your feedback on any issues with this driver here.
Is AMD expecting to service mobile Ryzens (eg Ryzen 5 2500U found in HP laptops) only through OEM's? The drivers seem to be reasonably old at this point and eg the above link clearly says only desktop models (Ryzen 2500G) supported. Also other Adrenalin builds do not seem to support 2500U that I could find.
