Public bug reported:
Hi!
It's seems that I'm unable to turn off LVDS on my MSI Wind. What's weird is a
fact, that I'm using my Wind with external monitor (VGA1) and, when LVDS1 is
disabled, screen suspend works (on VGA1).
This bug is easy to reproduce:
$ xrandr
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 4096 x 4096
VGA1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 408mm x
255mm
1440x900 59.9*+ 59.9*
1280x1024 75.0
1152x864 75.0
1024x768 75.1 70.1 60.0 60.0
832x624 74.6
800x600 75.0 60.3 56.2
640x480 75.0 60.0
720x400 70.1
LVDS1 connected 1024x600+0+0 (normal left inverted right x axis y axis) 220mm x
129mm
1024x600 60.0*+
640x480 59.9
$ xset dpms force off
[This turns off both screens for 1 second and then automatically turns it back
on - without any trace in dmesg]
$ xrandr --output LVDS1 --off
$ xset dpms force off
[And now everything works as expected]
I can provide more information on this, if needed. Just tell me what you
need.
