System:         Dell Latitude E6520

Configuration:  ALPS Touchpad (2 buttons) and Stick (3 buttons)


List of touchpad problems for Win7/linux:

1. Windows 7 64 bit, old DELL driver v7.1208.101.116


1.1 middle stick button does NOT work as scrolling
1.2 "the zooming" (designed as left-side scrolling) does not work well, zooming is jumpy, it look like that the sensitivity of this tool is very low and I had to really press hard my finger to get it at least somehow working
1.3 it is NOT possible to change the speed and sensitivity of the touchpad and the stick independently

2. Windows 7 64 bit, latest DELL driver (A08)

2.1 same as 1.1
2.2 same as 1.2
(problem 1.3 is fixed in a new driver) 


3. Linux ubuntu 11.04, all latest updates, latest Seth's driver

issues:
3.1 when changing sensitivity of the touchpad and the stick, it apparently does not have any noticable effect (unlike in windows)
3.2 the same problem as in early windows driver: touchpad and stick speed can not be changed independently.


4. General comments on comparison:

4.1 Both in win7 and linux the touchpad and stick are working "fine", it is possible to work.
4.2.in BOTH systems it is possible to enable/disable touchpad and stick independently 
4.3 Irritating in Windows:  vertical scrolling is very bad/insensitive and it is not possible to tune well; Works fine in linux
4.4 in linux, however it is not effectively possible to change the sensitivity of the touchpad and stick and it would be nice to have an opportunity to change that separately as in latest Windows driver.


Conclusions:  I personally like performance under linux (because of scrolling); it is now possible to disable touchpad and use the stick only (the left and right stick buttons now work; the middle stick button seems not working, but this also does not work under windows)

MANY-MANY thanks Seth !!!
