Hi, I've already submitted a bug request into the Ubuntu bug repo, but I am having huge issues getting anywhere with my HP Pavilion 15-ab141na laptop with the open source AMDGPU driver. Is the Ubuntu bug list the best place to get help with this? Currently the laptop is unused with Linux as the only way of using it is via fglrx on 14.04 (this however had power issues and wouldn't correctly wake from sleep) but on 16.04 it auto picks AMDGPU which doesn't seem to work at all, despite suggesting it should be supported. I suspect it could be power related as the vgaswitcheroo options just don't work and if you schedule changes via DDIS then you get null pointer references in the error log.
I understand the above is rather vague, I can go further into it but want to make sure im putting the info to those who will actually be able to help (I'm able to test things on this laptop as its not frequently used and the linux install is throwaway at the moment)
