Description Samuel Suther 2016-01-25 13:12:03 UTC

After Laptop (ASUS N76 VZ) wake up from sleep, Laptop-Screen keeps black.

Reproducible: Always




I have checkd the Syslogs and find out, powerdevil set Backlight to 0 for sleep.
Then I've tryed to push FN+Brightness up, and the screen gets visible again...

So may be a bug, that powerdevil not set the Backlight back to value which was set before Laptop go to sleep.

I've just tested this with my Dell Latitude and I cannot reproduce the issue.

Can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I'm setting status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thanks.

no clue, only close this outdated ticket.
