Upon looking at the code in evdev, it's clear the third button emulation is completely non-functional for multitouch devices.
The emulation is triggered by calling Evdev3BEmuFilterEvent() from EvdevPostQueuedEvents() in evdev.c. This is done for events of type EV_QUEUE_BTN only. With a multitouch touchscreen, events of this type aren't generated. Instead, the events are EV_QUEUE_TOUCH, which will never trigger the 3BEmu code. These touch events don't work the same way as button events, so it's not a simple matter of passing them to Evdev3BEmuFilterEvent() too. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/1084938 Title: evdev settings doesn't work at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1084938/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
