# Reload the Linux psmouse kernel module.
|
||
|
|
#
|
||
|
|
# Description:
|
||
|
|
# Removes and reloads the psmouse module, which controls PS/2 mice and
|
||
|
|
# touchpads on many Linux systems. This can resolve cases where the
|
||
|
|
# touchpad/mouse has stopped responding.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# ./reload-psmouse.sh
|
||
|
|
#
|
||
|
|
# Requirements:
|
||
|
|
# - Linux
|
||
|
|
# - sudo privileges
|
||
|
|
# - psmouse kernel module
|
||
|
|
#
|
||
|
|
# Notes:
|
||
|
|
# Reloading psmouse may temporarily disconnect the touchpad/mouse.
|
||
|
|
# Systems using a different input driver may not be affected.
