I have been having several issues with my touchpad since upgrading to 12.04LTS. I believe it is an issue with the Elantech driver. I have found that the following commands fix my problem, however, the changes seem to be reverted when I reboot.
modprobe -r psmouse
modprobe psmouse proto=imps
Is there a way I can make these changes permanent?
If you are using a generic synaptic touchpad, but it fails to respond to tapping or scrolling actions under a new installation, you can run the following two commands to immediately make it work:
modprobe -r psmouse
modprobe psmouse proto=imps
To make this change permanent, create a file such as touchpad.conf under /etc/modprobe.d/, and put the following line in it:
options psmouse proto=imps
Login as a super user (root) and open /etc/rc.local using nano or some other editor as shown below.
nano /etc/rc.local
and add the lines to the file
modprobe -r psmouse
modprobe psmouse proto=imps
Save Ctrl+O and Exit Ctrl+X and restart your system. It is done!
Alternatively,
Save your listed commands as a shell script (*.sh) and set that script to run before LightDM by doing the following:
sudo nano /etc/lightdm/lightdm.conf
Add this line to the bottom of lightdm.conf
display-setup-script=/home/[your username]/Scripts/synScript.sh
Or whatever your script is called and wherever it is located.
P.S. Don't forget to make your script executable!
.pc
I used crontab to schedule these commands at reboot. To do this I opened file crontab as superuser in folder etc:
sudo gedit /etc/crontab
Then I inserted a line at the end, so that the commands are executed as root at reboot (applied to every user):
@reboot root modprobe -e psmouse && modprobe psmouse proto=imps
I hope it helps!
