Hi,

I am having issues in using the touchpad of my Lenovo G460. When I try to move the cursor using the touchpad it moves it in some other direction. Also the touchpad buttons hardly work. And worse, using the touchpad also crashes the comp with the only option of restarting the system. I looked up on Google and tried different things around but nothing seems to work. Hence this post. Any help to solve this issue would be appreciated.

Here are some of my system details:

$ xinput -list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB Optical Mouse id=10 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=13 [slave pointer (2)]
⎜ ↳ Macintosh mouse button emulation id=14 [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)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Lenovo EasyCamera id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]

I am running on Ubuntu 10.04 (Lucid Lynx) and currently using the Linux kernel 2.6.32-27. Also as you can see from above, Lenovo G460 uses the ETPS/2 Elantech Touchpad.

If any more details are needed please let me know. Also if you guys think the solution is to rewrite the drivers, please give me some pointers on how to go about doing it.

Thanks and Regards,

Aravind

I had problems with Asus laptop using ETPS driver and debian sid. Originally the driver refuses to
load and the touchpad is just use as normal ps/2 mouse (except multi-touch scroll, everything works
fine in this mode); when I force load ETPS driver, movement and button are jumpy and buggy.

For my case, 2.6.35 contains these two changes that seems to fix the problems for me:

Input: elantech - discard the first 2 positions on some firmwares
Input: elantech - report position also with 3 fingers


I end up building patched psmouse module... Maybe disabling the elantech would be simpler...
