Touchpad to sensitive


The touchpad on my Lenovo Z560 is to sensitive. I went into the mouse setting and adjusted the pointer speed sensitivity as low as possible but I don't see any difference. The lightest touch will move the pointer. I saw where some have modified the xorg.conf file but I can't find it in Ubuntu 11.04. From what I could find with Google this laptop uses a Synaptics touchpad. I installed Gpointing-device-settings and was able to change the speed but not the sensitivity. How can I make the touchpad less sensitive?

xset changes mouse acceleration and threshold

xset lets me change the mouse acceleration and threshold but I can't find anything for sensitivity.

Hello rstuff,

I'm no expert in Ubuntu. On modern distributions there should be a directory /user/share/X11/xorg.conf.d/ with templates for various settings which once have been made in the xorg.conf file.
Chose one of the templates (on my system it would be 50-synaptics.conf) and copy it to /etc/X11/xorg.conf.d/ then you can edit and modify it to your needs, it is selfexplaining.

If you need more information about the possible settings for your touchpad, you may execute
Code:
synclient -l
in a terminal.

After changing the file in /etc/X11/xorg.conf.d/ you'll have to restart the X-server!

Markus

Not sure if Xserver is up

I did find the file /usr/share/X11/xorg.conf.d but when I try to run sysclient -l I get the message Failed to connect to X server. I ran top to see if I could find xserver and it told me that I had 150 some processes running but I could only see what fit on the screen and haven't figured out how to scroll down yet. I tried running startx and I got the message that the server was already active for display.

I did not have xserver-xorg-input-synaptics installed so I installed it. I have installed gpointing-device-settings which is suppose to supercede gsynaptics.

I will copy the template over and edit it and see what happens.

Thank you for the help.

You'll have to run the synclient command when X is running (with a gui). Open a terminal (xterm or konsole or whatever) and execute the command.

The errormessage "can't connect to X-server" means that you're on the commandline without X.

You can use synclient to test some settings, you should read the manpage
Code:
man synclient
For example
Code:
synclient PalmDetect 1
and check what happens. the list above (in you post) gives you a hint about which settings are available. Note that the settings will disapear when you logout.
But you may try to configure the settings in the file /etc/X11/xorg.conf.d/50-synaptics.conf so they will be preserved.

If I am not wrong you should reduce your "AccelFactor" value. Higher value means more sensitive.

synclient FingerHigh=65

Setting FingerHigh=65 helps. I used synclient to try different options until I found one that worked and then I copied 50-synaptics.conf and edited it and it is working better now. I learned a lot about the file system and editing files. Thanks for everyones help.
