I am having the exact same problem on one of my two laptops. First, please note I am not using Ubuntu or Kubuntu. I am running Arch Linux. I know this isn't an Arch Linux bug reporter, but wanted to note that this might be an upstream issue due to my having the problem on a different distribution.
Another thing worth noting is that my laptop with Intel graphics doesn't seem to be bothered by this bug (though I only use that laptop around once a week or less). My Nvidia laptop has this issue. So I'm thinking: Either this is a KDE bug, or an Nvidia bug. Are you guys running Nvidia? Although we use different distributions, our interests are the same, so I hope we can pinpoint the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/952521 Title: Screen blanking and dpms can't be turned off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/952521/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
