Touchpad Randomly Fails at Startup

[helpseeker]

When I boot up linux mint, sometimes the touchpad will cease to work. I'll have to restart 1-5 times (or more) in order to get it to work. Every time this happens I noticed that the kernel was displaying a message: 'i2c designware controller timed out'. I've tried everything from adding grub parameters, to upgrading the kernel. I would appreciate the help

Cinammon Release Notes: Touchpad drivers


To know which driver is used by your input devices, run the following command:
grep -i "Using input driver" /var/log/Xorg.0.log

The default touchpad driver in this edition is "libinput" (provided by xserver-xorg-input-libinput).

If you experience problems with it, you can switch to another driver called "synaptics" (provided by the xserver-xorg-input-synaptics package).
---

When both drivers are installed, "synaptics" takes priority.

To switch to the "synaptics" driver, install it:
apt install xserver-xorg-input-synaptics

Then log-out and log back in.

To go back to using "libinput", simply remove the "synaptics" driver:
apt remove xserver-xorg-input-synaptics

Then log out and log back in.
---

You can also try installing the "evdev" driver (provided by xserver-xorg-input-evdev):
apt install xserver-xorg-input-evdev

Then log-out and log back in.

To go back to using the "libinput" or "synaptics" driver, simply remove the "evdev" driver:
apt remove xserver-xorg-input-evdev

Then log-out and log back in.
