Asus U44S laptop with Optimus Nvidia Geoforce GT 610M. Slightly different but related issue. Can suspend with by closing the lid which didn't work in 15.10, although only without an external monitor plugged in. But upon resume getting a hardware lockup and freeze nearly 100% of the time. Initially it worked, but then has since stopped working. Using Nvidia binary driver 361.42 with the Intel card turned off under software control.
Just noticed something odd though as writing this up. Additional Drivers lists the Nvidia drivers OK, but for the Intel card it is now reporting "Unknown: Unknown - This device is not working." After upgrading to 16.04 from 15.10 I double checked and it reported the Intel card turned off from Additional Drivers. Clear, something has changed. ** Attachment added: "Additional Drivers" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574125/+attachment/4645942/+files/Screenshot%20from%202016-04-25%2006-33-43.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574125 Title: suspend not working after uprade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574125/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
