I had the same issue on an E7450 laptop. Linux rune 4.6.0-040600rc4-generic #201604172330 SMP Mon Apr 18 03:32:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
I had upgraded the kernel, but this didn't fix the issue. I upgraded the bios to a12, and now I can suspend and my display comes back. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1573760 Title: screen remains black after hibernation or suspend to RAM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1573760/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
