I disabled the touchpad on my Dell Latitude E6400 through the System > Preferences > Mouse > Touchpad option under Ubuntu Jaunty. After some period of time, say 5-10 minutes, it becomes live again on its own. When this happens, the touchpad tab disappears from the System > Preferences > Mouse options window. This has been happening for at least a month, perhaps since I loaded Ubuntu (I loaded 8.10 in March and upgraded to 9.04 in April). I have kernel 2.6.28-14-generic and Gnome 2.26.1. The problem does not occur if I have a USB mouse plugged in. The problem stops (temporarily) if I shut down and restart the laptop. Today for the first time, upon observing the problem, I tried typing gsynaptics in a terminal window. I received a message that SHMConfig needed to be set to true. I found a suggested addition to the /etc/X11/xorg.conf file and added it: Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "SHMConfig" "on" Option "HorizScrollDelta" "0" EndSection After adding this and rebooting, I was able to run gsynaptics, which showed the touchpad deactivated. Later, when the touchpad reactivated itself, I tried gsynaptics again, and received the message about needing to set SHMConfig to 'true'. I have a second problem that is perhaps related. Sometimes the left touchpad button fails to result in any action when it ought to, for example for a menu choice. Often the button functionality returns afte 5-10 seconds. Sometimes I have to shut down the laptop with the power button and then restart to remove the problem. This problem I occurs also with the USB mouse, however, so I am not sure that it is related.
