Bug Description
Using the touchpad does not result in expected behavior. The touchpad has three "mouse" buttons on top, and none of these buttons currently function. Using xev does not show any output from these buttons. The touchpad itself works fine. There are two bottom buttons integrated with the touchpad, which do not work consistantly. The left button will sometimes act like a left-click and sometime like a right click, making it hard to move applications on the screen. The right button acts like a left click and only sometimes bring up menus. Trying to change from a left hand to a right hand mouse in mouse options does not change the behavior.

Hello.
I got a new Thinkpad E420s the otherday and have come across a odd problem.
This laptop has a touchpad and a trackpoint. Sometimes the trackpoint will be detected and sometimes it will not.
Distro: Arch Linux
When the trackpoint is detected:
*rmmod psmouse results in mouse0 and mouse2 disappearing (ls /dev/input). mouse1 = usb logitech mouse
*modprobe psmouse results in mouse0 (the trackpoint) being detected and created right away. However, it takes about 20 seconds for the trackpoint (mouse2) to be created.
When the trackpoint is NOT detected I simply have mouse0 (touchpad) and mouse1 (usb logitech mouse)
Work / Solution
*Reboot into Windows 7. Insure trackpoint works (always does). Reboot into Linux device is detected. In my tests it seems that the device stops getting detected after 6-8 reboots. However, I did also have the problem after resuming from suspend-to-ram.
Let me know what information I need to provide and any way that I can help.
