Some news here, the suspend/resume process is doing fine (I checked while connected via ssh), but what I didn't notice because I was in a dark room is that there is just no backlight. But I find a workaround, setting acpi_osi="!Windows 2012" in the kernel command line seems to inhibit the issue. I found this workaround accidentally because I need this parameter to make my brightness control working again (I reported this in #702188 btw). > > > > > Cheers, > > Vincent > > > > -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
