>Synopsis: sometimes, waking up from suspend results in a black screen
>with the LCD turned off
>Category: system kernel amd64
>Environment:
System : OpenBSD 5.8
Details : OpenBSD 5.8-current (GENERIC.MP) #1616: Sun Nov 15
20:58:13 MST 2015
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
I had X with KDE running on my laptop, and I closed the lid, which
caused a suspend. When I opened the lid again sometime later, I didn't
see
anything on the screen, and the LCD backlight was turned off. Caps Lock
turned
on and off the indicator light, so the keyboard was working.
The dmesg and usbdevs info in this bug report is from after I forced a
restart.
>How-To-Repeat:
Unfortunately, I'm not sure how to replicate this. It doesn't happen
every time -- so far it's only happened once.
>Fix:
I don't know how to fix it.
