i had the same problem but you need change one line in xorg.conf
Option "SWcursor" "True"
but when I do that, I even had xorg.conf
so you follow this code if you have the same problem
Xorg -configure :1
#edit your xorg.conf.new in the line --> Option "SWcursor" "True"
#Copy xorg.conf.new /etc/X11/
cp /root/xorg.conf.new /etc/X11/xorg.conf
