There are a lot of different resolutions going on here, so I'll try to outline them.
- The spatial resolution of each event report is determined by the device itself. For example, I've seen joysticks axes have spatial resolutions of 20-85, 0-127, 0-255, and 0-4096. - The time interval resolution is also set by the device and mostly the OS respects that. Usually it is set to 10ms, which is plenty fast for most applications - [hid] has a settable poll time. [hid] polls the OS to get the events. It defaults to 5ms, IIRC, and can be changed. But there is really little reason to change this, and this functionality is being removed from [hidio]. The xorg settings won't affect [hid] at all, it gets the data directly from the kernel driver. The xorg data has been processed and converted into something that makes sense to control a mouse pointer on the screen. [hid] gives you just the raw data. .hc On Jun 26, 2007, at 12:16 AM, danja wrote: > Hi there, > I'm wondering about [hid] resolution, is [poll( something that has > to do > with it?
