Bug ID: 108561
Summary: nouveau: external monitor can not be enabled with
hindsight
Product: Drivers
Version: 2.5
Kernel Version: 4.2.5-1-ARCH #1 SMP PREEMPT Tue Oct 27 08:13:28 CET
2015
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri at kernel-bugs.osdl.org
Reporter: estellnb at elstel.org
Regression: No
Whenever I boot without an external monitor enabled then I get problems trying
to enable my u2868pqu monitor with hindsight. Xorg will recognize and it will
let me configure the external monitor. However the external monitor will stay
black and without a signal in spite of being configured well.
If I just reboot the X-server with the monitor cable unplugged then there
will be no problem in enabling my u2868pqu monitor. Consequently I would assume
this to be a kernel / nouveau module bug since it depends on boot time not on
the time when I start the X-server.
Is there any way to post the external monitor if I have booted without it?
What would you believe is going wrong here with nouveau and the HDMI port?
