Created attachment 144168 [details] dmesg utility output Starting X on AMDGPU takes up to a minute (about 40s, I think). I have two video adapters, integrated NVIDIA and external R7 240. It's only the first X startup after the boot that takes that long (and it's exactly Xorg executable which produces the delay). All subsequent X startups are 'normal' (fast). So I'd expect some system configuration option gets finally set after the 1st X startup, so maybe I could set it manually beforehand? However, there are those dumps from AMDGPU in the dmesg log. Didn't find anything useful on the net or in this BZ.
