--------------------------------------------------------------------------------- Hi, nothing leaps out at me - although I do note i915 is included in the later kernel modules - this chip is involved in the graphics and thus the X.org / X11 part of your setup - thus you may want to look through dmesg output and determine what kind of touchpad your laptop has. For synaptics this page may help http://www.thinkwiki.org/wiki/Synaptics_TouchPad_driver_for_X You will see that X.org is intimately involved with this and may well be the issue you have. Are you using default graphics card drivers? - sometimes changes to the kernel make X miss-behave. Try to use kmod aware drivers from elrepo - it makes life so much easier. http://elrepo.org/tiki/About Check out your /etc/X11/xorg.conf HTH > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos
