  This is generally a case of a kernel ('''linux''') or '''xorg''' bug.
  
-  1. Check by connecting an external mouse to see if that works. If it does, then one may be affected by the transition from [[https://launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics|xserver-xorg-input-synaptics]] to [[https://launchpad.net/ubuntu/+source/xserver-xorg-input-libinput|libinput]]. Hence, one will want to check by uninstalling xserver-xorg-input-synaptics to see if this resolves the issue. If not, please see below:
-   * After reading [[DebuggingTouchpadDetection/evtest|this]] about how to enter VT and log evtest events, switch to a VT using Crtl+Alt+F2 and enter the following in your terminal: {{{
- sudo evtest /dev/input/eventX > ~/evtest}}} where the "X" in "eventX" is the event number found by typing in a terminal: {{{
- cat /proc/bus/input/devices}}}
-   * Scroll, tap, drag, press buttons, and create various other possible events on the Touchpad. Then, press CTRL+C to exit and execute: {{{
- cp /var/log/Xorg.0.log ~/Xorg.0.log }}}
-   * Press Crtl+Alt+F7 to switch back to X.
-   * Add as separate attachments {{{~/evtest}}} and {{{~/Xorg.0.log}}} to the bug report.
