Bug#771718: general: Screen blanks and does not come back up unless system is suspended

[Rik Theys <rik.theys@gmail.com>]

Package: general
Severity: normal

Hi,

I was thus far unable to pinpoint which component causes this behaviour as I can
not find anything in my logs (and/or journal). I have therefore assigned it
to general. Feel free to change to a more appropriate package.

I'm using KDE on Jessie with gdm3 as the login manager. The system has
systemd installed. When the system is idle for few minutes (but before the
limit set in the KDE screensaver settings), the screen will blank and will not
come back on keypress or mouse movements. I have to close the lid of the laptop
to let the system suspend. After resume I will get the unlock window
of the screensaver and can continue working.

I can login using SSH when this happens but couldn't find anything in the logs
that could explain this.

Any ideas on how to further debug this issue is appreciated. Are there any
other reports about similar behaviour?

Regards,

Rik
