Re: [SOLVED] No display after waking up from sleep

Here is what I did finally:
Created a file /usr/lib/systemd/system/quirks.service with the following contents:

[Unit]
Description=Resume the backlight

[Service]
Type=oneshot
ExecStart=/bin/sh -c "sysctl -w kernel.acpi_video_flags=3"

[Install]
WantedBy=multi-user.target

Then the command systemctl enable quirks.service
Also modified the file /etc/systemd/system/systemd-suspend.service as:

[Unit]
Description=Suspend
Documentation=man:systemd-suspend.service(8)
DefaultDependencies=no
Requires=sleep.target
After=sleep.target

[Service]
Type=oneshot
ExecStart=
ExecStart=/bin/sh -c "echo mem > /sys/power/state"

A restart and everything worked.

Re: [SOLVED] No display after waking up from sleep

As suspected this was an open-source driver issue.
Fixed with proprietary driver (without using quirks).
