Comment 2 Laura Abbott 2018-10-01 21:12:37 UTC 
We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 28 kernel bugs.
 
Fedora 28 has now been rebased to 4.18.10-300.fc28.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
 
If you have moved on to Fedora 29, and are still experiencing this issue, please change the version to Fedora 29.
 
If you experience different issues, please open a new bug report for those.
Comment 3 phrogi 2018-10-15 11:55:21 UTC 
I have tested kernel 4.18.12-200 and the issue is still there - when I switch to full-screen or when powerdevil is trying to change monitor brightness, the laptop monitor goes to black screen.
Then I have to switch to text mode and back to graphical mode.
In my opinionI it is related to opensource nouveau driver, that doesn't work correctly. I have nvidia graphical card GF108GLM [NVS 5200M].

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There are a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 28 kernel bugs.

Fedora 28 has now been rebased to 4.20.5-100.fc28.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 29, and are still experiencing this issue, please change the version to Fedora 29.

If you experience different issues, please open a new bug report for those.
