After some time using the computer, the context menu suddenly opens and then the touchpad left button starts acting like the right button (left button starts opening the context menu instead of clicking). Looking at Xorg.0.log, I can see some "kernel bug" messages related to the touchpad. On dmesg, there is some error messages related to the touchpad too.
