In cyanogenmod settings under input settings there is an option for always pulse. Unfortunately for us this option is grayed out because it refers to the trackball. It does also work for the led light on our phones though. I much prefer my LED to blink when I have a notification even when the screen is on because if I am doing something that takes up the entire screen I otherwise may not notice the notification. Bugs me that this option is grayed out in CM6 so I decided to find a way around it. So what I did is pulled the cmparts.apk from CM6 RC2 for the Nexus One. You can download it here. http://dl.dropbox.com/u/7223192/CMParts.apk Just make sure you put it on your computer in the directory that you will be running adb from. Then reboot into recovery and mount /system Then go on your computer and ADB. Then adb push cmparts.apk /system/app Then reboot. You will now have the option in cyanogenmod settings to always pulse. You will also have the option to Trackball Wake and Trackball unlock although these options will not do anything.
