I think this problem is worse now. This morning I opened the lid to the laptop and I could see the entire desktop for over 1 minute but the system was not responsive but i could see the mouse and I could bring Unity sidebar to front. I do think I could change focus on witch windows should be in front (little unsure)
Suddenly the locked screen window appeared and after I logged in again the system started to work as usual johan@ubuntu-devnull:/etc/network$ uname -a Linux ubuntu-devnull 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux johan@ubuntu-devnull:/etc/network$ cat /etc/issue.net Ubuntu 12.04 LTS -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/390989 Title: [SecurityRoadmap] Locked screen shows the desktop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/390989/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
