Two monitors sometimes wake up from suspend, and other times they do not e.g.. Specifically, entering suspend and hitting the keyboard seems to wake up the monitors the first time. But clicking suspend the second time the monitors remain black. As a result USB devices connecting the monitors to the laptop with Displaylink cannot be found, and the Displaylink driver is deactivated. Only reboot works. Other usb connected devices to the dock work, such as keyboard and mouse. The issue seems independent of the lid position and does not occur 'intermittently'.

How to troubleshoot? Is the issue due to DisplayLink, suspend, or something else?

The following did not work:

I would not know what I would be doing:

Some possible involved files

/etc/tlp.conf 
/sys/bus/usb/devices/usb3/power/wakeup

/usr/lib/systemd/system-sleep/displaylink.sh
/usr/lib/systemd/system/displaylink-driver.service
/etc/udev/rules.d/99-displaylink.rules
/etc/pm/sleep.d/10_displaylink
/opt/displaylink/suspend.sh
/etc/pm/sleep.d/10_displaylink

log: suspend causes evdi to be disconnected/closed?

    I know this problem from a Dell notebook with a single monitor connected over the dock, but running MS Windows. How do you tell it's not a hardware problem?

  • Thanks for the question:-) I do not. Do you suggest a change to the question or how it is framed? Please upvote it if you think there is a reason to ask.

  • (1) Did you compare the system logs between a successful wakeup and a failed one? If there is a software problem, there should be a difference visible. (2) Another idea to narrow the problem: What about other peripherals on the dock? Do they work correctly?

  • @Philippos I attached the syslog as part of the DisplayLink Support Tool to the forum. The syslog is too long to be pasted in my question.
