Commen= t # 10 on bug 99316<= /a> from mat42x@yahoo.de 
I have also a Dell notebook with the same dGPU, but cannot rep=
roduce your error
with Ubuntu 16.04 kernel 4.10.0.

Instead I have the problem, that the dGPU only gets powered at a low freque=
ncy,
and becomes slower than the Intel GPU by doing so.=20

When I run glmark2, I look at "/sys/kernel/debug/dri/0/radeon_pm_info&=
quot; and
always see the following output:

default engine clock: 925000 kHz
current engine clock: 299990 kHz
default memory clock: 1000000 kHz
current memory clock: 148990 kHz
voltage: 1225 mV
PCIE lanes: 16

Btw.: This dGPU cannot be connected to a CRT directly, as there seems to be=
 no
connection available at all.
