I don't think DPI really falls into that category, it's a HW property, even when it's variable. So it looks like we need _some_ API to change it (udev properties?), I'm not yet convinced that a proper API is needed. What could work for those devices is to mark them as variable resolution and pick one resolution as the default. This also replicates the functionality as advertised by the vendor that changing the resolution changes the speed of the mouse. Maybe something like LIBINPUT_MOUSE_DPI="800" for a normal mouse and LIBINPUT_MOUSE_DPI="v800" for variable resolution.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
