Touchpad

Elantech wird erkannt von Kernel 3.2rc2 . rc3 bis rc6 erkennen es als PS/2 Mouse.

on the elantech front i found this post from mrmylanman in the archlinux forum saying he found a solution.
https://bbs.archlinux.org/viewtopic....31755#p1031755

he describes that the two handler for the touchpad /dev/input/mouse and /dev/input/event7 somehow interfere. but i can't reproduce his efforts on kubuntu 11.10 with the onceric RC6 kernel from kernel ppa.

for my elantech equipped znbook these handlers are

[ 7702.636] (II) config/udev: Adding input device ETPS/2 Elantech Touchpad (/dev/input/event7

  According to the intel-gfx list, the problem with rc6 seems to be related to VTd support, aka. virtualization. Adding "intel_iommu=off" to kernel boot line disables VTd, and should make rc6 stable, according to the reports
  And got the screen working on 3.2-rc3 with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=1 i915.i915_enable_rc6=1 pcie_aspm=force"
  This Bug is solved in Linux Kernel 3.2 rc6
