Comment 38 for bug 1767568

To Robie Basak, specifically with regards to #37.

The title of this bug already specified particularly that Console DPMS is not working. This bug report already was not about simply console blanking.

I understand that the original reporter said that he got it working with setterm, but as by convention these bug reports often require verification from others in order to get any attention, it seems only reasonable that after many have said that the DPMS power saving is what is not working, while simple blanking and leaving the monitor on is what is currently happening, that this bug should not have been marked invalid.

As many others have pointed out, Console DPMS power saving is not working in 18.04. It is clear after reading this thread as well as a few basic tests with setterm that nobody has working Console DPMS power saving at all in Ubuntu 18.04.

If this is only a matter of default settings as you seem to have concluded that it is, then please specify which optional setting re-enables Console DPMS power saving, because the following does NOT work on any of my Ubuntu 18.04 installations (as well as several others in this bug report) beyond mere blanking and leaving the monitor on:

in grub.cfg
consoleblank=600

setterm --powersave powerdown
setterm --powerdown 10

If this is just a kernel option that is no longer the default setting, then it should be specified here, in this bug report, what the appropriate change is to revert back to a very mature working functionality.
