Disable Synaptics Touchpad While Typing in Ubuntu
Sponsored Link
Open a Terminal from Applications -> Accessories -> Terminal
Type sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_synbackup
Type gksudo /etc/X11/xorg.conf
Enter your password if it prompts you.
Search for a section that looks like the following
Section "InputDevice"
Identifier "Synaptics Touchpad"
...
End Section
Add a line above the End Section line and put this into it:
Option "SHMConfig" "on"
Save the file and close gedit and the terminal window
Now you need to restart your desktop GUI using Ctrl-Alt-Backspace
Add the Startup Command
Open the sessions manager: System -> Preferences -> Sessions
Click the far right tab labeled Startup Programs
Click the Add button
Type in the following: syndaemon -i 1 -d
Hit ok then hit close
You can restart Gnome with the Ctrl-Alt-Backspace
To disable the touchpad completely, open your xorg.conf, and comment out or remove the line that says
InputDevice "Synaptics Touchpad"
in the "ServerLayout" section (it's near the bottom).
a feature i was searching for a long time, tks
just one remark why not use ”
copy/paste doesn’t work
Thanx, great trick I know from long ago. But after installing feisty it doesn’t seem to work, as syndaemon can’t access shared memory regardless of SHMConfig option on. What may be the issue? Any help is greatly appreciated.
Here’s my Input device part of Xorg.conf
Section “InputDevice”
Driver “wacom”
Identifier “eraser”
Option “Device” “/dev/input/wacom”
Option “Type” “eraser”
Option “ForceDevice” “ISDV4” # Tablet PC ONLY
Option “SHMConfig” “on”
EndSection
Option "SHMConfig" "true"
NOT “on”Minor typo fix. The line:
Type gksudo /etc/X11/xorg.conf
Probably should be:
Type gksudo gedit /etc/X11/xorg.conf
