Description of problem:
If screen goes blank I cannot get it to turn back on. This is from either a timeout (in power options blank screen after x time). Or by closing the tablet folio.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Dont use tablet for timeout value in power options.
2. Close the folio/keyboard.
Screen goes black and cannot be resumed. Have to power off the device and reboot.
Screen to come back on.
Not sure if I should even report this but it looks like I found an upstream bug similar to mine. I am using a Latitude 7275 2-in-1 so not sure if it matters.
Just an update but I tried switching to Rawhide and this issue persists. A lot of other issues with this particular hardware were resolved by the newer kernel though. However waking from sleep/monitor off is still broken.
*********** MASS BUG UPDATE **************
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 25 kernel bugs.
Fedora 25 has now been rebased to 4.9.3-200.fc25. 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 26, and are still experiencing this issue, please change the version to Fedora 26.
If you experience different issues, please open a new bug report for those.
Still a problem.
