<pre>When my machine awakes from 'systemctl suspend' my integrated LVDS display
comes up fine while an external HDMI monitor stays black with 'no signal'. As
far as tested the VGA output of my G96M will resume without a problem.
I have tested the following kernel parameters in addition to a plain boot
with nouveau.hdmimhz=225:
* acpi_sleep=s3=bios: resumes well but HDMI stays without a signal
* acpi_sleep=s3_mode: crash on resume with total blackscreen of LVDS as well as
HDMI, a hard reset is the only way out.
* acpi_sleep=s3_bios,s3_mode: same as s3_mode
kernel version: 4.5.0-rc1-ARCH #2 SMP
nouveau version of the Arch package: 1.0.12-1
Is there anything else I can try or do?</pre>
