Ubuntu 10.10 on HP Pavilion dm4-1160 - erratic pointer solved

Finally, I solved the erratic pointer with these parameters added at the end of the line of parameters passed to the kernel: i8042.nomux=1 et i8042.reset=1

From the Ubuntu 10.10 livecd, when the cd starts booting, press F1 to display the menu and F6 Other Options, press esc to remove the options box, and at the end of the line, add the options above:

Boot Options: file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash-- i8042.nomux=1 i8042.reset=1

synclient MinSpeed=0.1
synclient MaxSpeed=1
synclient AccelFactor=1
synclient JumpyCursorThreshold=60

I discovered the solution below doesn't work, but I found an alternative solution with synclient (it will be described in my next post)
If Ubuntu is already installed, edit the menu /boot/grub/menu.lst and add the options i8042.nomux=1 i8042.reset=1 at the end of the line kernel /boot/vmlinuz ... quiet splash !!!Doesn't correct the problem
