output of the dmesg command
Symptoms:
Login screen renders properly
Past login, the screen turns black, with the pointer visible and a blank pixel
in the upper left corner.
On some occasion the pointer turns from the arrow to the vertical bar.
crtl+alt+F<whaterver> works and brings the user to the tty.
all symptoms are reverted when the llvm driver is used.
System:
Ubuntu 16.04 Gnome edition (but even with unity installed and configured as
default the symptoms are the same)
AMD Radeon RX 480 8G
AMDgpu-pro 16.30
4.4 kernel
The dmesg file is the output of the command after a tty return with
ctrl+alt+F4.
