My monitors fail to wake up after going to sleep. While the HDMI cable connected and the workstation on, the monitor reported "Display Port: Inactive; HDMI:Inactive" and went straight back to sleep. The only way to reactivate is to hard restart the work station, which is unacceptable - a lot of work progress lost. Does anyone have the same problem?

Something seems strange where I cannot follow the problem.

 

Does the monitor go to sleep but the computer is awake and running?  If so, then unplug the monitor and plug it back in.  Obviously this is a temporary fix and a slight improvement is to put the monitor on a switched outlet to make it easier to power off and on.

 

Does the computer go to sleep in addition to the monitor and then neither of them wake up?  If so, there is something wrong with the sleep function in the computer.  I have several systems running 18.04 but the run 24/7.  Go to askubuntu and see how to change from sleep to hibernate.  What is probably happening is ubuntu wakes up and thinks the monitor is already awake. In hibernate mode, the system actually shuts down and then turns back on which should handle the monitor better.  Just a guess but I have seen this same problem with windows and the solution was (1) to hibernate and (2) put all monitors on a switched outlet.

Hello CassLi,

My suspicion is that it's not your monitor failing to wake up when your computer wakes up, but rather your PC failing to wake up from sleep. Could you provide a little more information on your computer hardware? What kind of graphics card are you using? Do you have the proper video drivers installed?

Hi Matt429,

 

Many thanks for replying.

 

It seems that there are some files corrupted on my machine, causing weird issues. I posted the question originally trying to sort the issues out myself but decided to ask the uni IT to help because I wasn't getting anywhere. Hopefully this will be resolved soon without completely rebuilding the machine.

 

Best regards,

Cass
