Description Mirko Predosin 2016-11-03 19:10:54 UTC
Description of problem:
The mouse pointer will freeze after power cycling the display.  The mouse still works as I am able to navigate the desktop without the pointer.

The issue only happens while the main console is displayed.  If I switch to a different console i.e. CTRL-ALT-F2 then the problem does not occur.  I can go back to the main console i.e. CTRL-ALT-F1 and the mouse pointer works.

Version-Release number of selected component (if applicable):
Linux 4.8.4-200.fc24.x86_64
Xfce 4.12

How reproducible:
Always

Steps to Reproduce:
1. Login to XFCE
2. Power cycle monitor
3.

Actual results:
The mouse pointer freezes

Expected results:
The mouse pointer tracks the mouse movement

Additional info:
My PC is connected to a Dell U3014 over DisplayPort 1.2.

The issue does not happen when power cycling the monitor from a different console i.e. CTRL-ALT-F2

Comment 1 Mirko Predosin 2016-11-04 16:09:12 UTC
It looks like the issue is worse than originally reported.  Sometimes the entire desktop freezes after turning the monitor back on.  I'm able to switch to the other consoles just fine.  Also, the issue doesn't happen when I first switch to a text-based console before power cycling the display.

Comment 2 Mirko Predosin 2016-11-04 16:21:08 UTC
If I restart lightdm from another console then I can get back to a login prompt on the desktop without rebooting.

> systemctl restart lightdm

I'm doubting this is a xfce4-power-manager issue, but rather a video driver/kernel one. :) 

Can you get the issue to occur, then dump out the last part of the journal log and attach that here? should be 'sudo journalctl -n 500 -b > /tmp/journal.log' from a vty. 

Thanks!

journal log

Here is a journal log showing the problem.  It starts when the monitor is power-cycled and ends after lightdm was restarted from another console.

I don't see anything in there that points the finger at anything specific. :(

Anything in ~/.xsession-errors?

Comment 6 Fedora End Of Life 2017-07-25 23:45:52 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bug reports from releases that are no longer maintained.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.

Comment 7 Fedora End Of Life 2017-08-08 19:08:16 UTC
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 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.

Thank you for reporting this bug and we are sorry it could not be fixed.
