I am currently experiencing this problem with my Lenovo X220 Notebook under Ubuntu 12.04, `lsmod|grep video` shows `i915`. But I've seen the same problem for years(!), on e.g. HP Z400 with Nvidia graphics and Ubuntu 11.04 and 11.10. The black-screen-lock happens either on sleep- resume and even after just locking the keyboard (lock, wait till display goes to sleep, move the mouse, display wakes up, mouse cursor visible, but nothing works).
So for me it looks like it is not related to particular hardware or driver - happens in compiz/unity with different hardware. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/966744 Title: [i965] Resume from suspend leaves me with black screen or a screen of the desktop before it suspended.
