Logitech TrackMan Marble FX scroll wheel patch for the Linux kernel

Logitech TrackMan Marble FX scroll wheel patch for the Linux kernel

NOTE I now have a standalone driver available here which is easier to install:

This patch alters the usbmouse kernel driver to support a "scroll wheel mode" using the fourth button (the red button) when connected through a "ID 04d9:1400 Holtek Semiconductor, Inc. PS/2 keyboard + mouse controller" usb-to-ps2 adapter. No idea how things work with other adapters.

It seems the fourth button generates events, but the state of the button is not represented in any bits (at least by said usb-to-ps2 adapter).

Using IntelliJ UI Designer for creating Swing forms in the Ceylon (1.3.0) language

I wanted to create a Swing app in Ceylon and figured I'd give using the UI designer a shot. Here are the necessary steps to get it to work:


Change IDEA settings

  • From the menu: File -> Settings
  • Navigate to Editor / GUI designer
  • Make sure "Generate GUI into:" has Java source code selected
  • Change "Default accessibility for UI-bound fields:" is something else than "private", for example package-private
  • Click OK to save
