| Subject | black screen after hibernation |
| Message-ID | <v78Yh-13o-1@gated-at.bofh.it> |
I have strange problem with hibernation (to disk) on my laptop. After resume my screen remains blank. (It is similar to https://lists.debian.org/debian-user/2017/01/msg00177.html, but in my case it is regardless if monitor was off before hibernation) System appears to be alive (can ssh to it, and can see my running processess) Keyboard working (I can enter password, and enter some text "blindly") But I cannot turn on my monitor. I tried to play with: echo 2000 |sudo tee /sys/class/backlight/intel_backlight/device/intel_backlight/brightnes but without success. There is not suspected in logs except: --8<---------------cut here---------------start------------->8--- 2018-01-12T15:11:23.637383+01:00 bambus systemd[1]: sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight.device: Installed new job sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight.device/nop as 1004 2018-01-12T15:11:23.637689+01:00 bambus systemd[1]: sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight.device: sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight.device lost dependency Wants=systemd-back light@backlight:intel_backlight.service 2018-01-12T15:11:23.637931+01:00 bambus systemd[1]: systemd-backlight@backlight:intel_backlight.service: systemd-backlight@backlight:intel_backlight.service lost dependency WantedBy=sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight. device 2018-01-12T15:11:23.638170+01:00 bambus systemd[1]: systemd-backlight@backlight:intel_backlight.service: systemd-backlight@backlight:intel_backlight.service lost dependency ReferencedBy=sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backli ght.device 2018-01-12T15:11:23.638398+01:00 bambus systemd[1]: sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight.device: sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight.device lost dependency References=systemd -backlight@backlight:intel_backlight.service 2018-01-12T15:11:23.638568+01:00 bambus systemd[1]: sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight.device: Job sys-devices-pci0000:00-0000:00:02.0-drm-card0-card0\x2dLVDS\x2d1-intel_backlight.device/nop finished, result=done --8<---------------cut here---------------end--------------->8--- Any hints?
