@Anton I have the exact same touchpad as you. I don't think this is related to the 7.4 firmware. I do not recommend the changes to synaptics.h that you posted. The newer Synaptic touchpads can either utilize a new multitouch protocol or the old absolute protocol. The Linux kernel does not currently support the new multitouch protocol so it uses the old absolute protocol. The touchpad doesn't report its multitouch capabilities when it is in the old absolute mode. However, 2 finger emulation still works by using the touchpad's width property to determine how many fingers are on the touchpad. You may need to play with some of the options in /usr/share/X11/xorg.conf.d/50-synaptics.conf if 2 finger detection doesn't currently work for you. Try playing with these options: Option "TapButton2" "3" Option "EmulateTwoFingerMinW" "5" Option "EmulateTwoFingerMinZ" "90" Option "VertTwoFingerScroll" "1" Option "HorizTwoFingerScroll" "1" Option "VertScrollDelta" "100" Option "HorizScrollDelta" "100"
Sorry for the off topic post. Multitouch problems should probably be handled elsewhere. -- Synaptics Clickpad touchpad buttons are not working https://bugs.launchpad.net/bugs/582809 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
