Public bug reported: Horizontal scrolling with the middle trackpoint button on Thinkpad X260 does not work as expected. I noticed the problem in nedit, where holding the middle button while dragging the cursor over the text to be copied is a fast way of copying text. But the cursor does not move, so this feature does not work. In chromium, scrolling works with the cursor in place, but this is not the same functionality as with a real mouse, which is what is supposed to be emulated. This all worked perfectly in Ubuntu 10.10 (what I have been using until now).
The difference between scrolling with the middle button of a real mouse and the broken emulation is that with a real mouse, xev sees a ButtonPress event (button 2) followed by MotionNotify events, followed by a ButtonRelease event, whereas with the trackpoint it sees a series of ButtonPress and ButtonRelease events (buttons 4,5,6,7) with no MotionNotify events. Completely different behavior from what an application is expecting. Since this worked in a previous release, is there some work-around? ** Affects: xserver-xorg-input-evdev (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1597984 Title: horizontal scrolling with middle trackpoint button broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1597984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
