Hi all
Much as the title. New PC, fresh install. Using KDE system settings I have the monitor set to turn off after 30 minutes. What actually happens is the screen goes blank but the monitor remains active and doesn’t go into standby, suggesting the system is still sending the monitor some sort of active signal. This behaviour is not my previous experience with this setting, when the monitor would go into low power standby. Any ideas please?
Regards
Fred
By way of a bit of a bump (apologies), but in the spirit of answering my own question:
I’ve noticed that in this install, although it’s on a tower PC, the power settings are full of inappropriate items - notifications for low battery etc. which I’ve not seen previously. Could it be that the installer mistakenly took this for a laptop, and that’s the reason it’s not initiating a power-down for the monitor? If this is possible, could anyone suggest how I can get it to switch to a desktop mode?
Cheers
Fred
I can understand your thoughts. but that’s not the case, there is no such thing as laptop/desktop mode, in fact the system doesn’t care. Can you create a new user, login as that user and check whether the situation is the same for that new user? If so, that would exclude settings in your homedir and make it a system issue. In that case we would have to find out what is going wrong in the powermanagement re. putting the monitor in stand-by.
OK, thanks for the clarification. On a new user account, the same problem persists.
I’m struggling to see what the material difference is between the old PC and the new one in this regard, as I’m still using the same monitor as before. One thing has occurred to me. Because the monitor is old, it only has VGA and DVI-D inputs. The new PC on the other hand only has HDMI and DisplayPort, which I was told was back compatible… So the connection I’m using is via a DisplayPort to DVI-D cable. I’m now wondering if this arrangement is perhaps interfering with the standby message.
