Description of problem: Black Screen after wakeup from standby Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Screen stays black Expected results: After wakeup from standby you should be able to just use the computer again Additional info: Everything was normal until the intel driver got updated. Now after standby the screen stays black and doesn't wake up
I'm seeing something similar, but I'm not sure if it's an x driver bug, a kernel bug or an interaction. Today I updated to xorg-x11-drv-intel.x86_64 2.99.917-19.20151206.fc23 and xorg-x11-drv-nouveau.x86_64 1:1.0.12-3.fc23. If I boot with the latest kernel (kernel-4.3.5-300.fc23.x86_64), when I wake from sleep I get a black screen with a cursor that responds to mouse movement. I can switch to a text tty and log in. If I reboot and select kernel kernel-4.3.4-300.fc23.x86_64, resume works. MacBook Pro (MBP 6,2), Xorg.0.log shows nouveau and intel drivers loaded, but nouveau selected.
I'm having the same issue (screen stays black after coming back from display sleep) with: kernel-4.3.5-300.fc23.x86_64 xorg-x11-drv-intel-2.99.917-16.20150729.fc23.x86_64 If I upgrade xorg-x11-drv-intel to 2.99.917-19.20151206.fc23, and reboot, the screen stays black when coming back from display sleep. If I downgrade back to 2.99.917-16.20150729.fc23.x86_64, the screen comes back on after display sleep. I've tried digging into the system journal but I can't find anything useful there. Here's a peculiar workaround I found: * Boot with 2.99.917-19 loaded * Log into GNOME * Press Windows-L to lock the screen * Wait a few seconds for the display to sleep * Wiggle the mouse (screen stays black) * Connect an external display via DisplayPort * Screen comes on and I can log in * Disconnect external display That's not a pleasurable workaround by any means, but I hope it helps with the troubleshooting. :) I'm on a 4th gen ThinkPad X1 Carbon with an i7-5600U with Intel HD Graphics 5500.
After more testing, the old kernel just let one sleep/wake cycle work. The second would result in the black screen on wake. But if I downgrade the nouveau driver to xorg-x11-drv-nouveau-1.0.12-1.fc23.x86_64, things work. So it seems like a common issue in nouveau and intel drivers.
Same here. Downgrade of the xorg-x11-drv-nouveau package helped, so it must be an issue in the latest version there.

For the time being you can remove the newest and install previous: (I have Fedora 23) sudo dnf remove xorg-x11-drv-intel; sudo dnf install xorg-x11-drv-intel-2.99.917-16.20150729.fc23.x86_64; The appears in version 2.99.917-19.20151206.fc23
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
