Subject: [Bug 108561] nouveau: external monitor can not be enabled with hindsight
Date: Tue, 15 Dec 2015 18:56:12 +0000	[thread overview]
Message-ID: <bug-108561-2300-CIAO6jGFz8@https.bugzilla.kernel.org/> (raw)
In-Reply-To: <bug-108561-2300@https.bugzilla.kernel.org/>

--- Comment #3 from Elmar Stellnberger <estellnb@elstel.org> ---
s2ram; new test results:
* when booted with nouveau.modeset=0 the external monitor is not enabled at all
(i.e. definitely a bug related to the nouveau kernel module).
* suspecting this to be backlight issue I have tried to boot into runlevel 1
with the following kernel parameters the nouveau module being loaded
 - video.use_bios_initial_backlight=0
 - video.use_native_backlight=1 
 - acpi_osi=
 Unfortunately none of the above kernel command line parameters did yield any
difference with respect to s2ram: the external monitor always got disabled by
suspend.
