Hi all, this problem affect my netbook (Samsung NB30P) since squeeze 6.01. I had not find my way through Google and all (i find some old pages about pre- inkernel elantech patches to synaptics, but not more). The problem is that, wathever shmconfig/xorg.conf.d or fdi or udev i use, my touchpad cannot scroll (horiz and vert) in a reasonably predictable way, more than a scrolling it is a "jumping" and quite randomly (to the top, the middle, the bottom, the third...): a mess. A WORKAROUND to this issue is to `modprobe psmouse proto=imps', but this completely disable twofinger horiz scroll, and in a netbook that is very annoying. Thank you for all the fish, and sorry for my bad en, Pier Paolo. PS: Even errors or operations on Xorg.log are quite random, some times it loads a Machintosh mouse, fore ex. This is recurrent instead: Query no Synaptics: 6003C8 Ref. to Debian bug 626507 for attachments too: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626507
I did not understand if my (this) bug is a duplicate of 21614 (https://bugs.freedesktop.org/show_bug.cgi?id=21614), however if someone explains to me what means this patch on gmane (http://article.gmane.org/gmane.linux.kernel.input/7121/match=elantech) we all better understand those reports according to me. 'cuse me but i'm in a hurry, Pier Paolo.
This appears to have been fix by the kernel commit 7f29f17b57255b6395046805a98bc663ded63fb8 Author: Éric Piel <E.A.B.Piel@tudelft.nl> Date: Thu Aug 5 23:51:49 2010 -0700 Input: elantech - discard the first 2 positions on some firmwares
