Some laptops have touchpads with non-standard aspect ratio. Currently they are quite painful to use since the driver does not compensate the ratio. In my HP 2510p moving finger vertically moves the pointer twice as fast as moving it horizontally. Same has been reported at least on HP Mini-note and Lenovo S10. Issuing SYN_QUE_RESOLUTION on 2510p returns "units per millimeter" values infoXupmm=74 infoYupmm=160. For another laptop with normal touchpad they are 81 and 95. I believe the reported absolute coordinates need to be compensated according to units per millimeter in order to get even speed in both directions. I tried to study how to expose the values to user space but didn't find anything obvious. Would it be correct to do the compensation in synaptics kernel driver instead of xorg? -- Tero -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
