Dell XPS M1530 touchpad drivers?

Asked by Kevin S

I installed Ubuntu and it seems to run just fine except the trackpad. Every time I touch it the cursor just goes crazy! I is clicking and jumping all around. I can plug in a mouse and that mouse works, but I would like to be able to use the trackpad. Also even with a mouse plugged in, when I bump the trackpad it messes everything up. Are there drivers or something for it?

Hello Kevin,

Excuse my bad English.

It seems that the problem is known https://bugs.launchpad.net/ubuntu/+bug/216797.

You can try to change the boot file grub/boot/grub/menu.lst

To do this, you can use an editor like gedit in root mode (ALT+F2 -> gksu gedit /boot/grub/menu.lst -> root password).

You must change the following line (add i8042.nomux=1):

Forward:
#defoptions = quiet splash

After:
#defoptions = quiet splash i8042.nomux=1

Secondly, we must run this command in a terminal (Accessories / Terminal):

sudo update-grub
[sudo] password for xxxx: root password

Then restart the machine.

I can not test because I do not have the same machine but I hope it will help you.

 Hi i had the dell xps M1530 touch pad problem as well.
First i opened a root terminal. typed the (sudo -i) then edited the xorg.conf file by tiping (gksudo gedit /etc/X11/xorg.conf) it opens gedit with xorg.conf loded for editing,
looked for the input device section(
 "Section InputDevice"
       Identifier "Synaptics Touchpad"
 Driver "synaptics"
 Option "SendCoreEvents" "true"
 Option "Device" "/dev/psaux"
 Option "Protocol" "auto-dev"
 Option "HorizEdgeScroll" "0"
        Option "SHMConfig" "true"
EndSection
) i added the option "SHMConfig" "true"

saved it
then typed
(gksu gedit /boot/grub/menu.lst -> root password) root password is your root password, in the root terminal.
then updated the line (#defoptions = quiet splash) to read (#defoptions = quiet splash i8042.nomux=1)
saved it & then updated the grub file bye typing (sudo update-grub) in the terminal
restarted... my laptop
all good i even have the touchpad option in the mouse property's, RE -system - Preferences- mouse
thanks for the help..
:)
