Determine whether a touchpad has been detected To check if a touchpad has been detected open a terminal and check the input device list given by this command:
xinput list If one of the lines mentions a touchpad or glidepoint (perhaps also "Synaptics" or "ALPS"), your touchpad has been detected. If one of the lines mentions an "ADB mouse", then your touchpad is old. Use the trackpad command line tool to configure it. Here's an example to switch on tapping and dragging: sudo trackpad showsudo trackpad tapsudo trackpad drag Enabling SHMConfig in order to get synclient debug output Online, the most commonly found procedure for doing this involves using HAL. However, since HAL hasn't been present in Ubuntu since 10.04, you will have to do it the other way -- by editing xorg.conf. sudo gedit /etc/X11/xorg.conf Paste this into the document: Section "InputClass" Identifier "enable synaptics SHMConfig" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Option "SHMConfig" "on"EndSection If it's not empty, put it at the end. Save, close the file and reboot. Now you should be able to see what kind of input your touchpad detects by running synclient -m 100 The synclient manpage will explain what the numbers you see onscreen mean. Touchpad not working after login This usually happens when you disable your touchpad and then suspend your computer. To fix this just run this command: gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true If nothing else works, please see the official Ubuntu touchpad debugging article <https://wiki.ubuntu.com/DebuggingTouchpadDetection>. Control touchpad features using synclient synclient is a commandline utility to query and modify Synaptics driver options. This would allow one to adjust touchpad features that may not be exposed via the GUI. One would adjust parameters via a terminal: synclient PARAMETER=# where PARAMETER is as listed below, and # is a number. While the formal definition of each parameter may be found in the synaptics manpage, here is a more user friendly description of each of the parameters: LeftEdgeRightEdgeTopEdgeBottomEdgeFingerLowFingerHighMaxTapTimeMaxTapMoveMaxDoubleTapTimeSingleTapTimeoutClickTimeEmulateMidButtonTimeEmulateTwoFingerMinZEmulateTwoFingerMinWVertScrollDelta - Controls the speed and direction of vertical scrolling. The fastest natural direction scroll speed is 1. Larger positive values decrease the scroll speed. The fastest reverse direction scroll speed is -1, with larger negative values decreasing the scroll speed.HorizScrollDelta - Controls the speed and direction of horizontal scrolling. The fastest natural direction scroll speed is 1. Larger positive values decrease the scroll speed. The fastest reverse direction scroll speed is -1, with larger negative values decrease the scroll speed.VertEdgeScroll - Enables=1/Disables=0 vertical scrolling when dragging across the right edge of the touchpad. HorizEdgeScroll - Enables=1/Disables=0 vertical scrolling when dragging across the right edge of the touchpad.CornerCoastingVertTwoFingerScroll - Enables=1/Disables=0 vertical scrolling when using two fingers anywhere on the touchpad.HorizTwoFingerScroll - Enables=1/Disables=0 horizontal scrolling when using two fingers anywhere on the touchpad.MinSpeed - Adjusts the minimum speed of your touchpad cursor. Lowest is 0.MaxSpeed - Adjusts the maximum speed of your touchpad cursor. Lowest is 0.AccelFactor - Adjust the rate of speed increment at which the touchpad cursor increases from MinSpeed to MaxSpeed.
