Title:
Ubuntu 18.04 touchppad does not work smoothly in Lenono Thinkpad
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hallo,
The touchpad is not working after installing Ubuntu 18.04.1 LTS in Lenovo
Thinkpad laptop. After a lot of googling and trying around, I managed to make
it work in the sense that i could move cursor here and there, but still it has
numbers of problems. Here is the list of problems it still has:
1. The scrolling does not work at all, it never worked.
2. It is dead after each restart and I have to provide this commands to make
it work, so that the cursor could move.
sudo modprobe -rv psmouse
sudo modprobe -v psmouse proto=imps
3. The typing of the keyboard does not work smoothly, which make me really
difficult to work. For example: I ended up typing this
''he list Here is the pr to repoty I want thatoblem of t''
when I want to type:
'Here is the list of problems that I want to report'
4. The left and right touch is really hard.
Here is the information on my touchpad
