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-X, which is subscribed to xorg in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
