I have an ASUS K53E laptop. my laptop touchpad is being recognized as a PS/2 mouse in 11.04. And hence I can't see the touchpad tab in the System Settings>Mouse.

Here's the output of the 'xinput list' command in 11.04:

parth@parth-K53E:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ USB 2.0 Camera id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10[slave keyboard (3)]

But recently I tried to boot 12.04 off a live cd (actually a thumb drive), the trackpad worked. I can now see the touchpad tab in System Settings>Mouse. Here's is the output of the xinput list command:

parth@parth-K53E:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ USB 2.0 Camera id=9 [slave keyboard (3)]
↳ Asus WMI hotkeys id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

Any ideas?

You could try to figure out which module is being loaded in 12.04 for your touchpad and try to build that out in 11.04. Figuring out the exact device might help - it's an Elantech touchpad it seems? Maybe lspci or lshw would help.

Or...just live with it in 11.04 til 12.04 is released.

both lspci and lshw are showing me all the hardware info other than the trackpad and keyboard...
