Xinput set-prop " USB OPTICAL MOUSE" "Device Accel Constant Deceleration" 8.0įor my mousepen, with 8.0, I get about an A3 sheet's worth of mousing now to cover the whole screen! To reduce the mouse speed, meaning you mouse over a larger area, use factors larger than 1.0. In amongst that lot is the property you need to change - number 251. Note there is a spurious space before "USB OPTICAL MOUSE", yes, you actually need that space if you have the same cheap mouse I used! SIGMACHIP Usb Mouse id=10 <- system mouse I use the device name, not the id number, as the name of the device is fixed in hardware, and assigned id numbers may change!įind the NAME of your mousepen device, by typingĮxample output Virtual core pointer id=2 Note that this tweak only affects the named mouse device, so you can use a regular system mouse AS WELL as this device, they both work. No settings are needed in the applications, but to slow the mouse "speed" right down, while keeping resolution needs a tweak.Īdditionally, this tweak was put into a "udev" rule, so that it is applied whenever this mouse is plugged in. I use this device under Linux, with GIMP (bitmap) and Karbon (vector) tools. It's like when a child writes/draws with a pen held in a fist! This takes away the finest level of control. When holding a mouse: Your fingers are usually in a locked position for operating buttons, and sprawled over the mouse.
When writing/drawing on paper: Fine control comes from flexing two fingers and a thumb, medium control from wrist/hand rotation, and coarse control from arm movement. It means that tiny errors, tremors, sticking/mistracking of the mouse are magnified. That is like trying to draw on a large postage stamp.
With a mouse: My screen is 540mm diagonal, yet I'm drawing in a box around 45mm diagonal.
You can traverse the whole A4/A3 sheet to fit the drawing in. Why is drawing with a mouse hard? The two main blockages I came up with were. I usually end up sketching with a pencil/pen and scanning the result in, before continuing digitally from there. Freehand detailed drawing/artwork with a mouse is harder work than with a pencil.
