Hi, New to Ubuntu, been a CentOS user for the last 15 years. Just working on a new box - ASUS MINI PN50 with Ubuntu 21.04 fully updated. System CPU is an AMD Ryzen 7 4700u with radeon graphics x8
I have two 27 inch screens, one via DV and other via HDMI
Under settings power I have enabled "dim screen when inactive" and set blank screen to 5 minutes, auto suspend is off as I need the machine to be up 24x7 but want the monitors to turn off after 5 minutes.
I have searched and read lots of junk but most talks about Xorg which I believe is not in use with 21.04.
I have tried xset dpms and get
server does not have extension for dpms option
search on this phrase also doesn't help.
I have libxcb-dpms0 is already the newest version (1.14-3ubuntu1)
not sure where to head next.
Finding quite a few subtle differences between my CentOS 7 experiences and Ubuntu. It seems to be aimed at Windows type users and assumes a little too much for my comfort.
i.e. when a wifi link has no internet access it just takes it upon itself to look for other wifi links - not what I need when I'm configuring a new network device and want it to stay locked to the link I select.
I have tried a number of solutions but NetworkManager (?) thinks it knows better.
Was contemplating using Ubuntu for some servers but this kind of take-over-control is not acceptable.
Anyway, first things first - need to get my monitors to go into power save mode after 5 minutes.
Suggestions please.
Rob
