[Bug 308191] Re: Multitouch support not available for Synaptics touchpads v7.2

 

I don't know if I should report this here or in the clickpad buttons bug
https://bugs.launchpad.net/bugs/582809

I've tested the 1.1.0 package, and it compiles Ok and works of for two finger scroll and three finger paste.
But with clickpads, you cannot click+drag, because as they heve a full sensitive surface with no physical separated buttons,
when you press the touchpad with a second finger to make the click, the driver detects two fingers and so, stops the cursor and start scrolling. Same happens if you made a click, and with the finger pressing the surface (in button area) you put another finger to drag the thing below the cursor.
Testing Win7 synaptic driver behaviour, it seems that it takes into account the delay or time between one finger and two finger touchs. i.e.,
If you put two fingers in the touchpad more or less simultaneously, it behaves as two finger detected and start scrolling, but
if you put first one finger, and then the second finger with some delay  (~0.5s or more), cursor moves as if only one finger was detected, and so, you can click and then touch and drag. Same if you are moving one finger on the touchpad (moving the cursor) and then touch with other finger to do a click for example, the driver behaves as if only the initial finger was over the touchpad, allowing you to click with the other.
In fact, it seems that Win7 syn. dirver doesn't use the area marked as left buttton for anything, you can click+drag or move+click or scroll with two finger simultaneously in any place. The only diference is when you make the click in right-bottom area designated as right button, that it then behaves as right click.
