Bug#886302: pm-utils: Black screen when resuming from pm-suspend-hybrid
Package: pm-utils
Version: 1.4.1-17
Severity: normal
When I run `pm-suspend-hybrid` the screen goes black and the system suspends. When I wake it up, the screen does not go "un-black". The system is definitely awake, because I can ssh into it, but I can't go back to what I was doing because of the black screen.
The screen is not *off*, because I can see that it's still backlit, but it's only showing black.
Both `pm-suspend` and `pm-hibernate` work as expected; only `pm-suspend-hybrid` has this problem.
`pm-is-supported --suspend-hybrid` returns 0
The laptop is "ASUS Laptop X Series X550ZE-WBFX", or at least that's what Newegg calls it. It has an AMD Radeon R5 M230 GPU, if that makes a difference.
