I have a Dell Inspiron 5567 notebook computer which comes with AMD Radeon™ R7 M445 discrete graphics along with Intel® HD Graphics 620 (Standard). It runs elementary OS Juno.
Before I installed elementary OS Juno, I had a previous version of elementary OS (it was Loki as per my memory).
On the previous elementary OS version, my R7 graphics option was visible in my "System Settings -> About" page.
After installing Juno the R7 was not visible in the "About" page.
When I search for the graphic driver in AMD's support page (https://www.amd.com/en/support/graphics/amd-radeon-r7-series/amd-radeon-r7-400-series/amd-radeon-r7-m445), as of today (6th of May 2020) there are no drivers for Ubuntu available.
My questions are:
- How did I have the drivers working for my previous installation?
- Is there anyway for me to get AMD graphics working on my new installation? (Obviously without bricking my laptop)
When I run
lspci -v | grep -B8 -v "Kernel modules: [a-z0-9]+" on the terminal I get the following graphics related lines.
