Comment 172 for bug 296610

Thank you, Robert! Your instructions were very clear and helpful.

Some obvious touchpad bugs are clearly fixed on my E6500. I'll keep an eye out for the other odd ones which were more sporadic, but so far, so good.

For others attempting this on Jaunty, I'll point out:

- The referenced alps-dave-2.6.31.patch is available in the "Patches" section towards the top right of the launchpad bug page.

- The patch had a couple rejects with the Jaunty kernel. In the first one, it was pretty easy to see where to change the file drivers/input/mouse/alps.c so that this line:
       { { 0x62, 0x02, 0x14 }, 0xcf, 0xcf, ALPS_PASS | ALPS_DUALPOINT }, /* Dell Latitude E6500 */
  instead read like:
       { { 0x62, 0x02, 0x14 }, 0xcf, 0xcf, DELL_STYLE_DUALPOINT },
  The second patch reject was just comments.

- The final copying can be done a bit more easily using the commands:

  sudo cp /lib/modules/$(uname -r)/kernel/drivers/input/mouse/psmouse.ko \
   /lib/modules/$(uname -r)/kernel/drivers/input/mouse/psmouse.ko.orig

  sudo cp ~/kernel/ubuntu-jaunty/drivers/input/mouse/psmouse.ko \
   /lib/modules/$(uname -r)/kernel/drivers/input/mouse/psmouse.ko

- Install the new kernel module using:

  sudo rmmod psmouse
  sudo modprobe psmouse

If there's any way this can get into Jaunty it will make a lot of people happy, but I'll try to spread the word to the folks I know who have been hurting.
