Ahh, yes, you're right. Disabling compositing does give the correct behaviour (screen is black at unlock dialog).
The option was at WIndow Manager Tweaks. I'm not sure what the 'previous tab' is that you're referring to (I have Placement, and that's not relevant). I did find that unchecking 'Display full screen overlay windows directly' on the same tab made the problem go away. -- xubuntu Gutsy: Screensaver shows user's screen at password prompt https://bugs.launchpad.net/bugs/160636 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
