[Bug 648671] Re: Touchpad on Thinkpad T400s doesn't support two-finger scroll
This turns out to be a combination of several issues: The kernel driver likely does not have a driver for the touchpad which supports multiple fingers. The touchpad however does support reporting fingerwidth and can therefore be used with two-finger emulation. Two-finger emulation cannot be turned on using the Gnome Mouse capplet. See Gnome bug #625163 Even if one turns on two-finger emulation using the xinput interface, two-finger scrolling does not work. This is because, on Ubuntu, the default value for the property Synaptics Two-Finger Pressure is 280, which is much too high. A Fedora 14 Live CD i booted for testing, had a default value of 29 for that property. Indeed, lowering that value under Ubuntu makes Two-finger scrolling work. See the upstream bug for more info. I don't know why this pressure default value is wrong on Ubuntu. It could be due do a different synaptics version, or due to a patch in Ubuntu? -- Touchpad on Thinkpad T400s doesn't support two-finger scroll https://bugs.launchpad.net/bugs/648671 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
