I investigated some more time in this problem and saw, that when I start with "nomodeset" and "fb=false" and running pm-suspend from terminal my pc was ready to go into standby... also problem was wakeup.. there I left with a black screen.
because of this I installed nvidia binary driver and there I am also ready to go into deep sleep (S3), but again I get a black screen. Switch to a other Terminal (ALT+F1) not working, but i see disc activity... only hold power key is possible. So finally: what can I do that nouveau driver or nvidia driver works with S3 ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993598 Title: stand-by stopped to work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/993598/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
