Thank you. I am now starting to wonder if perhaps udev is now in the kernel?
For anyone who happens to tick udev on in the gui service tool; you may lose the keyboard, then be unable to type in the password to untick it. There are a couple of ways out of this...you need another computer or at least a livecd. Make a text file with your password in it. Save it to a memory stick. Move the stick back to your linux computer. Now unplug the usb mouse and the stick and replug them. You should now have the mouse back and you can copy and paste the password when you go to run the services gui. Then untick the udev box, and any other that you might have activated. Reboot.
Or you can boot into runlevel 1 by editing the kernel line...just type the space bar while booting. Follow the directions and add a number 1 at the end of the kernal line. You might have to type your password. The type service udev stop ,
then type exit. The desktop will start, and then you have to use the gui to untick the udev service in the gui. I dont know why but you will see that it is still ticked even though you stopped the service as root. Then reboot and all should be back to "normal".
