Bug Description
Steps to reproduce:
- observe touchpad click-drag* working normally (i.e. can click touchpad and drag an icon, or select text in any direction)
- close lid to suspend (need to wait some time until red Thinkpad light above 'i' on lid starts to flash
- open lid to resume
- observe touchpad click-drag NOT working. Can click but not drag, or can only drag very short distance/awkwardly
*depressing the touchpad surface until it clicks, with one finger (usually index) and with the touchpad clicked down, dragging on the touchpad with another finger (middle) to move the item selected via the click.
typical uses to test: click a window titlebar and move it using drag
click a desktop icon and move it using drag
click to being select in text area of an app and drag to extend selection
Also note:
- sudo moidprobe -r psmouse
- sudo modprobe psmouse
restores expected functionaly
Similar symptoms to several related bugs (see below) but reporting separately, since:
- issue still present on later hardware and software than previously reported
- issue still present despite full firmware updates
- slightly different experience with workaround (i.e modprobe -r psmouse / modprobe psmouse does restore functionality
