I see my bug was marked as duplicate and that it affects nvidia- graphics-drivers-535.
Some additional info: - 550 nvidia driver had same issue when I tested. - Does not occur just on hibernation, but also if the screen turns off because of inactivity. - Waking the monitors causes a loop of "no signal" every few seconds on one of the monitors without ever showing an image. - Logging out after this issue occurs fixes it instantly. - Turning off the problematic monitor and then turning it on after waking the computer up sometimes work, but some times it causes a crash that just shows the sad computer face with the only option on screen being to log out. Very annoying issue as I can't lock the computer(or use hibernation), as that causes the monitors to turn off. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065081 Title: [nvidia] Secondary monitor does not wake up when returning from hibernation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-535/+bug/2065081/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
