I got around this dpms-is-always-disabled nuisance in Xubuntu 16.04 by calling a bash script in ~/.config/autostart/<something>.desktop. The script sleeps for 10 seconds and *then* calls xset in such a way as to enable dpms. The 10-second delay is evidently long enough for the startup of the X session to be completed, along with the disablement of dpms that appears to happen during session startup but, alas, after the contents of the autostart have been processed.
I had earlier tried uninstalling light-locker, BTW, but it didn't help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/924278 Title: xscreensaver doesn't enable DPMS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xscreensaver/+bug/924278/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
