Mouse Accessibility depreciated

[David K Parker <davparker gmail com>]

FYI,

To begin with, I'm a double arm amp, left below elbow, right at the shoulder. I wear a single prosthesis and use a hook. I've worked it the IT field for more than 20 years. I depend on accessibility features to use a computer. I've tried switching to a Linux desktop for my primary computer a number of times. I've always been able to mostly duplicate the accessibility features found in Windows OSes, albeit historically taken more work to configure. 

I recently bought a second laptop and want to take another serious stab at Ubuntu. I discovered the ability to configure clicklock functionality has seemingly been removed. It appears that Mousetweaks is set to use Dwell clicking, which I find about useless. I'm not sure why a simple clicklock feature, by pressing and holding a mouse button briefly, is not a default configuration option. This is a much more useful option than all the work needed to try and master dwell clicking. Fortunately Windows 7 has all the accessibility features I need.I really would like to take another crack at Ubuntu, but a simple accessibility feature is a major hurdle. Enough to prevent me from doing anything more with my Ubuntu install.

Also, for laptops, enabling configuration options for trackpoint would be a huge benefit. Simply being able to easily enable press-to-select and sensitivity would be most helpful. As it is, I now have to create scripts, like so:(, or worse, trying to figure out how to configure sysfs)

echo -n 1 > 

/sys/devices/platform/i8042/serio1/serio2/press_to_select 

echo -n 120 > /sys/devices/platform/i8042/serio1/serio2/speed
echo -n 160 > /sys/devices/platform/i8042/serio1/serio2/sensitivity
echo -n 10 > /sys/devices/platform/i8042/serio1/serio2/inertia

For a disabled person with any significant exposure to commandline would not stand a chance.

Thanks,

David
