Agreed. Perhaps you could work out a function. The size of the cursor should be proportional to DPI. For a screen of size 'screen_size', if I double the dpi, then I want to double the number of pixels for the cursor. Agreed? If the screen_size is halved, then you probably don't want the cursor size to be halved - but you do want to shrink it a bit. It is unclear whether this is a linear function. Perhaps we could try to work out the best size for a cursor on an ipaq, the best size for a cursor on a 14" screen, and the best size for a cursor on a 21" screen, and try to fit that to a linear/quadratic function, and then test that against some other size screens. cursor_size = A(screen_size)*screen_size*dpi*accesibility_ratio Where A is a function of screen_size, and returns the ratio, and accessibility_ratio is the value in the kde/gnome accessibility panel for doubling the size of the cursor etc for ppl with poor sight (NOT intended for people with normal sight trying to see the cursor on their large screen - that would be in the function A) Thoughts?
