I copy here the text (i've also make some modifications) from an offtopic report by me in the multitouch bug #308191
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 have 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 the first finger and the second 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. driver doesn't use the area marked as left buttton so much. You can click+drag or move+click or scroll with two finger simultaneously in any place. The main diference is when you make the click in the right-bottom area designated as right button, as then behaves as right click. MacBook buttonless clickpads, have no marked area for left and right button, and so, left button works as stated before in Win7. Right button has the difference, and is triggered only if you press right-bottom area of touchpad (more or less the same as Win7 but with a greater area for W) and if you make the click with two fingers on pad. Triple click would work with three fingers clicking simultaneously over the pad. This last behaviour (Mackbook) is very intuitive and could avoid to define the marked areas that differ between touchpads, making it a more universal solution for clickpads. I'm sure that i've not stated anything new here, but just for knowing your opinion... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/582809 Title: Synaptics Clickpad touchpad buttons are not working -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
