Title:
Missing graphics drivers for AMD Ryzen 5 with Radeon Vega 8
Status in xorg package in Ubuntu:
New
Bug description:
I have recently installed Ubuntu 19.04 on an ASUS TUF Gaming FX505DY
laptop. The laptop has a AMD Ryzen 5 with Radeon Vega 8 processor.
No warnings where raised during the installation process regarding
problems with the graphics driver. When I connected a HDMI connected
monitor I found it did not work.
I have attached the graphics driver logs

*********************************************************************************
QUESTIONS
1. Why is the problem with unsupported drivers not flagged during the
installation process? The default driver does work for the laptop's
monitor, but will not drive a second monitor attached to the HDMI port
2. I have seen reference to a general purpose AMD graphics driver,
but there is no reference to this driver being supported on Ubuntu
19.04. If I went ahead and attempted to install the general purpose
graphics driver, how would I back it out if it did not work.
I have raised this issue as a "question", but I think it is probably a
bug but I could not find out how to raise a bug associated with a lack
of device drivers.
