I have a dell inspiron 15-5000. The touchpad gestures work fine most of the time. After the computer is in sleep, they sometimes do not work. I can't determine an exact pattern. They return upon a reboot of the machine.
I have reinstalled the Dell OEM-specific drivers and tried to install the generic synaptics ones (that install failed). Any other suggestions?
It seems that others might have had this issue, but I found no definitive solutions in the other threads on the forum.
