I tested my system with the driver from git on X server 1.9.3 (Fedora 14). I see full pressure up to 2048. So, it does look like something unique to your system/device. > i believe both issues are connected and relate to distorted value > translations from serial to X, as you remember isdv4-debugger output was > seemingly acceptable (in sense of pressure levels it was fine). If isdv4-debugger output is right, it likely means that the device is not something we can blame. > Anyway, my primary concern is, I have about ten pressure gradations in X > (gimp) and there are all 256 visible in isdv4-debugger. Peter worked on isdv4-debugger. I am not very familiar with that tool. But if it reports the correct value, I guess we can trust it. > I guess if I had entire pressure range I won't even encounter this false > clicks, because they would fit into Threshold. I guess so too. It might be something between the raw data is processed and posted, i.e., maybe the pressure was not posted properly to XInput. > So what it could be? wrong driver settings? buggy X? or some inaccuracies in > input-wacom driver? How comfortable are you with debugging the driver? Tracing into the code is the most reliable way to figure out the root cause of the issue. The two files that you can pay a bit of attention are: wcmISDV4.c and wcmCommon.c.
