Description Jan Hutař 2016-10-25 04:38:43 UTC 
Description of problem:
When I resume from suspend (suspended on docking station with external monitor attached by disconnecting power and closing laptop lid), screen sometimes stays black (Lenovo ThinkPad T540p) and Ctrl+Alt+F2 followed by Ctrl+Alt+F1 does not help (usually it helps).


Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.18.4-4.fc24.x86_64
kernel-core-4.7.5-200.fc24.x86_64


How reproducible:
sometimes, say 1 of 5 times


Steps to Reproduce:
1. Being on docking station with external display, disconnect power from dock
   and close lid with power-manager set to suspend in that case
2. Resume and notice screen is black (though fan seems to be running)
3. Ctrl+Alt+F2 followed by Ctrl+Alt+F1 does not help (usually it helps to
   resurrect the screen)


Actual results:
Do not know how to get screen back


Expected results:
Screen should start normally

Comment 6 Fedora End Of Life 2017-07-25 23:36:07 UTC 
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. 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bug reports from releases that are no longer maintained.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 '24'.

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 24 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.

Now on F26, this seems extremely rare or not happening.
