Sorry It was wrong that I wrote on 27th Oct. On first reboot everything was seeming ok but next reboots I had same. And I had been tried too many thing and I installed too many drives and program. Actually my observation was wrong and the problem still goes on.
So I installed the OS 15.10 from the beginning (I remove old OS but home directory still same due to several reason) But the problem still goes on I dont know what should I do. -- 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/+bug/1500925/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
