Tapping with Touchpad with Kernel 2.6

I had been running Mandrake 9.x on a laptop which was working fine. Then I upgraded to Mandrake 10 Community and now I am running Mandrake 10 Official Download on my Laptop. Everything is running fine except that When running with the 2. Kernel I cannot tap on the touchpad. If I boot with the 2.4 kernel I can tap with the touchpad, so the problem seems to be with Kernel 2.6. It seems that the kernel 2.6 insists that the toucpad is a "Universal - any PS2 & USB" mouse while kernel 2.4 reports it as a "PS2 - Standard" mouse. Someone please help me to get tapping working with kernek 2.6 on my laptop

They removed it from 2.6 kernel.
But you can add psmouse.proto=imps to your kernel line in /etc/grub.conf like this:
kernel /boot/vmlinuz-2.6.6-1.435.2.3 ro root=LABEL=/ rhgb quiet psmouse.proto=imps

But however it doesn`t work after reboot. You have to shutdown your machine completely.

Usefull link:

It`s explained in the link I posted:

//Putting it at the end of the append
append="devfs=mount acpi=ht resume=/dev/hda6 splash=silent psmouse.proto=imps"
//Putting it at the end of accuall image
initrd=/boot/initrd.img psmouse.proto=imps

Try forcing the ID of the device to be a synaptics touchpad. That worked on my SuSE 9.1 laptop.

I've added it in Mandrake linux append as suggested and it now works a dream.
I'm very happy now running on a 2.6 Kernel with tapping working on my touchpad

Many Thanks

I tried the psmouse.proto=imps and didn't get the touchpad back. Do I then have to change the mouse setting to get it to work? (Laptop Mandrake 10 using Logitech 2button USB mouse).
But funny thing, after changing the boot menu, when I logged on as guest in my machine (another user I made for friends to borrow the computer) and started X I got a weird GUI called "ICE sw" or something and the mouse worked but didn't automatically highlight menus that were selected as happens in Gnome, KDE and most Windozes. I don't know if this is related though I doubt it.
--gaviidae (still using a mouse :)

EDIT maybe I didn't really change it at all? I was root, went to /boot/grub and then vi menu.lst and insert typed the psmouse after the vga=somenumber and ZZ'd it, it said changes made but it was a read-only document so maybe did I go to the wrong place?

When I try type "/boot/vmlinuz-2.6.6-1.435.2.3 ro root=LABEL=/ rhgb quiet psmouse.proto=imps"

is only says

"bash: /boot/vmlinuz-2.6.7: Permission denied" even though I do it as root? I'm running slack 10.0.

How can I fix this?
