Hi, I would like to report a bug for Debian stretch, however, I'm not sure which package I should file the bug against. Moreover, I haven't found a way to debug the issue either.
I've recently done a fresh installed of stretch on an HP EliteBook 840 notebook. Since then, the laptop's screen sometimes turns blank, i.e., as if there is no input to the screen. Strangely enough, whenever I attach another display, the other display doesn't go blank: It's only the internal display of the laptop itself that turns completely black. I've tried to debug the issue by looking a various log files (e.g., ~/.local/share/xorg/Xorg.0.log, /var/log/kern.log, running `journalctl`), but nothing would show up in these logs whenever it occurs. I also tried to install `firmware-linux-nonfree` but that didn't help either. Before, I was using jessy without the bug. I hope you can tell me which package I should file the bug to, or how to proceed from here. Best, Tim
