I just discovered this the hard way. I happened to have speedtest.net opened in an unfocused Chromium tab on an inactive workspace and spent quite a bit of time going through a wild goose chase trying to figure out why my previously reliable DPMS/screen-locking setup suddenly flat- out refused to work at all. This was just running in the i3 window manager; no Gnome or KDE, nothing fancy. Closing the tab involved, or Chromium altogether, makes it work again.
The closest upstream bug I could find is https://bugs.chromium.org/p/chromium/issues/detail?id=654659 , but it appears to have been basically ignored by the developers. It seems that Chromium has issues with inhibiting power management too aggressively. So aggressively I'd almost call it abusive. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1600622 Title: Screen doesn't lock or go to sleep when certain Chrome tabs are open To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1600622/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
