I turned on my Aspire One last night and the touchpad was totally non-responsive. To use my laptop, I needed to get a mouse. The touchpad has worked fine for me for more than a year now. I am using Lubuntu 18.04.3 LTS. With the mouse, I was able to use my computer, and write this.
In trying to troubleshoot, I did what others have advised. I ran:
$ cat /proc/bus/input/devices
I got back the following:
I: Bus=0018 Vendor=06cb Product=74a3 Version=0100 N: Name="Synaptics TM2985-009" P: Phys=i2c-SYN1B82:00 S: Sysfs=/devices/pci0000:00/808622C1:00/i2c-0/i2c-SYN1B82:00/0018:06CB:74A3.0001/input/input5 U: Uniq= H: Handlers=mouse0 event5 B: PROP=5 B: EV=b B: KEY=e520 10000 0 0 0 0 B: ABS=6f3800001000003
I also ran
$ xinput list and got back:
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Synaptics TM2985-009 id=11 [slave pointer (2)]
I am new at this. From what I can tell, reading online, this indicates that the problem is most likely not with the kernal; perhaps the issue is either with xserver-xorg-input-libinput or xserver-xorg-input-synaptics. I checked, and both are installed on my machine. I also looked up the publishing history for those two; they appear to have been changed on 2019-10-18. That confused me because my touchpad broke only recently. I'm not sure what to do next. I'd like to get this working again.
