I can also confirm this problem Ubuntu 9.04 Jaunty 2.6.29-02062903-generic #02062903
Happens on average 2 - 3 times a week. only way to recover is a power off via button. Thinkpad R60 with i945GM Intel graphics with compiz effects turned on and default black screensaver. After locking the laptop the screen goes black and no amount of mouse or keyboard activity will enable the unlock login box to appear. Hard disk appears to have light activity when buttons are pressed but nothing displays. Are there any logs i need to be looking for or enabling to debug this issue?
