How to get IMX53QSB Touchscreen to work???

[BobWeiman]

I am using an IMX53QSB with the Freescale LCD (Seiko). I have it running under the Ubuntu download. I can move the cursor by touching the panel. However, I can not tap and start an application. It all works fine using the mouse. A mouse click starts the application but a tap on the touchscreen won't

What do I need to do to get the Tap function working?

I forgot to mention that I have a Rev A board. I believe there is different PMIC on the Rev B board.

I tried updating the evtouch driver figuring that might help. It did not. The LCD would not come up at all.

Any suggestions?
