My last temporary solution on that issue: After locking screen, When the screen goes to black I press any key Than the brightness of screen comes back And never goes to black.
But If I forget to press any key Or after reboot if I cannot login on the time, Screen goes to black and the solution is reboot the system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1500925 Title: Ubuntu 15.10 Idle freezing/screen not waking up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/light-locker/+bug/1500925/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
