Horizontal scroll on maximize/restore window control restores window.

[Otus]

To reproduce: maximize a window, move the mouse cursor to the maximize/restore window control (the square) and use the horizontal scroll with the mouse. The window restores to non-maximized state.

This is annoying with a mouse where tilting the middle button/scroll wheel scrolls horizontally. It is easy to do by accident when trying to send the window to background. I imagine touchpads are likewise affected, e.g. when trying to hit the close button.

In Ubuntu 11.10 beta I cannot reproduce this bug though I can create bug 775872 Could you confirm if the issue happens for you in 11.10 beta?

[Otus (jan-varho)]

I don't have an oneiric installation to test right now, but at least on natty it actually requires a "double scroll" - i.e. two scroll events within the double click time. If you don't have a mouse with horizontal scroll, using xmodmap to remap mouse buttons also works.

In fact, I think both this bug and 775872 are the same bug: the global menu treats any Button Press event except for buttons 3-5 (middle click, vertical scroll) the same as 1 and 2 (left and right click) and opens a menu / restores the window. The same is true for indicators.

To reproduce you can e.g.

xmodmap -e 'pointer = 1 2 3 6 7 4 5'

and scroll over the global menu or

xmodmap -e 'pointer = 11 2 3 4 5 6 7 8 9 10 1'

and left click.

(xmodmap -e 'pointer = 1 2 3 4 5 6 7 8 9 10 11' restores to normal.)

Currently horizontal scroll restores a maximized only if the mouse is inside the maximize/restore window control (the square). The horizontal scroll in the application/global menu opens it (bug #775872) while the horizontal scroll in the minimize window control (-) blows up unity.

  * debian/rules, debian/control:
    - add nuxabiversion capability as upstream is breaking a lot the ABI
      wasn't bumping the soname. Create a virtual package similar to what
      we already do in compiz to ensure we dep on the right version.
      Remove the makeshlibs override then as not needed anymore.
    - bump to nux 2.0 with new libnux-2.0-0, libnux-2.0-common, libnux-2.0-dev
      packages. Make the necessary changes in .install files as well
    - don't ship anymore the -doc package.
  * debian/nux-tools.install:
    - move the apport file there instead of the -common package to enable
      co-instability
