Vertical Ergonomic Devices for Linux?
NonNullSet asks: "I am having trouble finding a truly programmable mouse for Linux. I'm a longtime (read older) computer user and have to use an ergonomic mouse (http://www.evoluent.biz) to work on Windows. I would like to find something similar (vertical shape, if possible, programmable buttons) for Linux, but haven't had any luck. Have any Slashdot readers been successful at finding/using programmable ergonomic hardware on Linux? Vertical shape plus click and hold would be excellent!"
If the vertical mouse is USB, why wouldn't linux be able to pick it up as a four-button HID? As far as the machine is concerned all it should need to know is that it's got a pointer and some buttons...
Here is the xmodmap documentation you are looking for.
