I did not see the second post until now (I will try the conf file changes today once I get back home). I just tried the values from the first link that you had given. That is a very useful thread for my laptop - configuration of almost everything. However, the two-finger scrolling still doesn't work. I just followed a few links from the same link and I got to know that multiple detection of the touchpad could also be a problem (https://bbs.archlinux.org/viewtopic.php?id=104769
). Then, I noticed that though the "changes" document says that the /usr/share/X11/xorg.conf.d/50-synaptics.conf will be overread if the /etc/X11/xorg.conf.d/50-synaptics.conf file exists, this doesn't seem to be happening. I figured this out because of the multiple detection statements in Xorg.0.log:
[ 2351.416] (**) AlpsPS/2 ALPS GlidePoint: Applying InputClass "evdev touchpad catchall"
[ 2351.416] (**) AlpsPS/2 ALPS GlidePoint: Applying InputClass "touchpad"
[ 2351.417] (**) AlpsPS/2 ALPS GlidePoint: Applying InputClass "touchpad catchall"
I went ahead and renamed the 50-synaptics.conf file in /usr/share/... and also commented out the touchpad section in /usr/share/X11/xorg.conf.d/10-evdev.conf. This did overcome the multiple detection problem, but did not make the two finger scrolling work still.
As I type this post, I realized that the modprobe command I had put in rc.local probably is not required now and it may get detected automatically. I have to try this and the other suggestion in the last post. I will do that and get back another post. Thanks a lot. Hoping for some success!!
