Which version of xf86-input-wacom did you compile and install? Your best bet is to try the just released 0.11.0 version. There have been bugs that caused jumps in last 6 months but I believe all are fixed in current version. Also, your server is older than mine and so you may be hitting some bugs fixed in later server versions (there have been a few). At least make sure your upgraded to latest patched version from your distro. >> > >> > Maybe you could give me a hint where to start looking >> > for the problem.

There are two options to enable debugging. When turning on both, it will start printing the X/Y values to log file as you move your finger or release. If you see a X go to zero while "px = 1" (finger is touching pad) then you know its a xf86-input-wacom issue when it jumps to left. >> > >> > Under Windows and Linux the touch input has a "lag" >> > of about 300ms and I am not sure who to blame.

Is it only 300ms delay before first movement and then aligned or do you see timeshift of 300ms (last packet sent 300ms after lifting finger)? How are you judging this very short time period? Linux and Windows have different gesture logic *but* if you want gestures on any platform with any hardware there will be some sort of delay introduced while HW or SW is deciding if your moving finger around or doing a gesture which should not move cursor. The more gesture combinations supported, the longer the initial delay must be. Check the wiki page and look for the config option that allows you to disable Touch Gesture support. Turn that off and see if your lag goes away. >From my experience of monitoring data coming from "touchpad" devices, the bamboo is returning very good raw data. Overall, I think the devices works much better than the price point its at would lead you to assume.
