Buggy SynPS/2 Synaptics TouchPad
Publié le 12 Fév 2013, 3:09 am dans linux

Due to issues on keyboard, I recently fresh-installed LinuxMint 14 to my Lenovo 3000 N100. My former system was LinuxMint 11. Unfortunately, one annoying bug eclipses all the good aspects of this new system. My touchpad stops working many times, and when this bug happens, I can't use my mouse anymore to click anywhere. The pointer still moves but the clicks get lost. I have to go into console mode (Ctrl+Alt+F1) and kill the main application who lastly got the mouse focus.

Sometimes, it gets me back into graphic mode and the mouse is working again. But randomly, that doesn't fix the problem, and either X gets restarted automatically or I need to restart mdm manually.

The issue seems to be some kernel bug with since kernel 3.0, so I bet installing a new desktop manager or another linux flavor would just be a waste of time. Before I'll explore that way, I will list here my attempts to solve and see how long these workarounds last.

The first workaround I found, that I don't understand at all, is about some modprobe commands.

sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps
