Red Hat Bugzilla – Bug 1260393
display left unlocked after suspend
Last modified: 2016-01-17 17:54:06 EST
Description of problem:
On a laptop with Nvidia Optimus (two cards in tandem with passtrough)
X11 with the default configuration will create TWO displays, accessible via Ctrl+F1 and Ctrl+F2
They act at least semi-independently and systemd, locking, etc. only work with one of them (but not the other). systemd seems to be confused.
Among the effects: when closing the lid only one screens is locked, so on resume the other screen is wide open and unprotected.
This is a security issue that may merit a high level.
Version-Release number of selected component (if applicable):
Fedora 22 with latest updates + Bumblebee with proprietary drivers as detailed here:
Seems to be always reproducible.
May be closely related to other bugs re. suspend on lid close.
- Hardware: Dell XPS 15 (9530)
I realize now what the problem is.
Gnome Lock Screen will freeze the machine on restore from hibernation.
Could not test the remote access but the keyboard is frozen and the display is black.
Upgraded to Firefox 23
No longer an issue, no point is following up.
