Hello developers!

The problem still exists in hybrid VGA configuration. For example, my laptop
has discrete ATI HD 5650 card and integrated Intel card. There are 2 external
outputs, VGA and HDMI, but they are not used. Following is the report from
kernel:

---
# cat /sys/class/drm/card0/card0-LVDS-1/status 
connected

# cat /sys/class/drm/card0/card0-VGA-1/status 
disconnected

# cat /sys/class/drm/card1/card1-LVDS-2/status 
connected

# cat /sys/class/drm/card1/card1-VGA-2/status 
connected

# cat /sys/class/drm/card1/card1-HDMI-A-1/status 
disconnected
---

card0 - Integrated Intel (i915 module)
card1 - Discrete AMD (radeon module)


As you can see, kernel reports about 3 connected monitors, although only
integrated laptop's LCD is used and AMD card is disabled via vgaswitcheroo:

---
cat /sys/kernel/debug/vgaswitcheroo/switch 
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Off:0000:01:00.0
2:DIS-Audio: :Off:0000:01:00.1
---


By blacklisting radeon kernel module I can workaround the problem because
kernel reports only one card, but a drawback is the vgaswitcheroo interface no
longer available. Therefore I can't completely switch off discrete card.

Thank you!

Installed software:
 Kernel: 3.15.2
 systemd: 214
