running ubuntu 12.04 on compaq cq70 for about 6 months. only major problem i ever had was touchpad only worked for first 10 minutes after install. i just keep usb mouse in my bag.

while trying to fix that issue yesterday i tweaked /etc/default/grub after finding tutorial online. tweak killed my keyboard and never fixed touchpad. revert to backup didnt help.

reinstalled 12.04. then 10.04. then 8.04. then mint 14. then back to 12.04.

usb mouse works. touchpad and keyboard totally unresponsive.

random gestures are recognized by touchpad (dash opens and open windows get closed) and keyboard works in bios. im typing this very post using a usb mouse and on-screen keyboard. plz help b/c i have to type about 10k words per week for work.

12 hrs later, this on-screen keyboard is for the birds.

thnx
