To start try the following as root
my ex: is from RegHat
#gpm -t ps/2 -m /dev/input/mice
note /dev/input/mice could be diff on your system (Suse)
come to think of it What are your protection like ? here are the ones on my system
ls -l /dev/mouse
lrwxrwxrwx 1 root root 10 May 1 18:57 /dev/mouse -> input/mice
ls -l /dev/input/mice
crw------- 1 root root 13, 63 Jan 30 2003 /dev/input/mice
if that fails, try see what
#dmesg | grep -i "mouse"
reveals ... But, you probably have done this already !
J-P (pls Do not forget to assing points, tks)
Smile I will feel the difference
