Linux mouse gpm

The following gets the mouse working in the console;

gpm -m /dev/input/mice -t imps2

https://www.linuxquestions.org/questions/slackware-14/setting-up-a-usb-mouse-in-slackware-401496/

put the following in rc.gpm and make bootable - chmod +x /etc/rc.d/rc.gpm

#!/bin/sh
# Start/stop the GPM mouse server:

if [ "$1" = "stop" ]; then
echo "Stopping gpm..."
gpm -k
else # assume $1 = start:
echo "Starting gpm..."
gpm -m /dev/mouse -t imps2
fi

Finally do ln -si /dev/input/mice /dev/mouse to create link
For usb /dev/mouse points to /dev/input/mice
For PS/2 /dev/mouse points to /dev/psaux


Optionally add/comment the following lines in /etc/X11/XF86Config for usb

#Option "Protocol"    "PS/2"
#Option "Device"      "/dev/psaux"
Option "Protocol" "imps/2"
Option "Device" "/dev/mouse"

Slightly related note: for keyboard, the following should be present:
#Option "XkbLayout"  "us"
Option "XkbLayout"  "uk"
