Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021. I'm setting the status of this bug to 'Incomplete' as it's not seen any activity for some time. If this is still an issue when using a currently maintained release of Ubuntu then please let us know which one(s) otherwise this bug report can be left to expire in approximately 60 days time. ** Changed in: xorg (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1662042 Title: Black screen after resuming from sleep with nvidia drivers on 16.04 Status in xorg package in Ubuntu: Incomplete Bug description: This happens on an ASUS ZenBook UX303UB, with nvidia-375 installed. I'm able to connect to the host through SSH. I have run the apport-bug tool when the display was black. The problem is not present when I switch back to using the Intel GPU using Nvidia's tool (through nvidia-prime). So far, I have done the following tests, following reports from other users: - Switched to kernel 4.8 - Tried with both nvidia-370 and nvidia-375 - Tried with fix to backlight (http://askubuntu.com/questions/820955/blank-screen-after-resume-dell-m5510-ubuntu-16-04/823523) - Configured ligthdm idle-timeout to 3 seconds and see if the display came back (due to an old bug affecting older versions) Bumblebee is not installed. I have seen several issues / questions that seems similar to this one, but I couldn't find a solution / workaround, other than disabling Nvidia's GPU. I appreciate any help to debug this.
