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
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.
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!
Created attachment 1217452 [details] 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?
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.

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.
