I recorded the events with evemu as you suggested, let me explain the steps that I did 1) First I uninstalled the xf86-input-driver, because when this driver is installed the strokes behave correctly, even if Xorg.0.log shows me that libinput is used as driver. 2) Then I rebooted the system and made sure that libinput is used as driver by checking xorg log with grep -e "Using input driver 'libinput'" /var/log/Xorg.0.log I got Using input driver 'libinput' for 'Wacom Intuos4 6x9 Pen' 3) Then I opened krita with a document of 1920X1080 snapped it on the left side of the screen and snapped the terminal on right half of the screen. I then tested the stroke, which were wavy as I showed you earlier. I then proceeded to record the events with evemu as you suggested with evemu-record > pen.evemu , i got a prompt to enter the number of event which was 17 I am attaching the log here as **pen-evemu** 4) I then replayed this event in a new document as you suggested and the wavy lines were reproduced. 5) I then installed xf86-input-wacom and commented the tablet related lines in 40-libinput.conf like i mentioned in my earlier comment to make sure xf86-input-wacom is used as driver 6) I rebooted the system, check the xorg log to make sure libinput is not used for wacom, I got the output of grep as - Using input driver 'wacom' for 'Wacom Intuos4 6x9 Pen' 7) I then proceeded to check if replaying earlier recording would reproduce the wavy lines. this time the event number was changed to 5, so I had to change the number from 17 to 5 in while replaying with sudo evemu-play /dev/input/eventX < pen.evemu. There was not stroke made and nothing happened. 8) The strokes were smooth and perfect with wacom driver, I then re recorded event with evemu as saved the recording as **pen-wacom.evemu**. I am attaching this log too. **this is with xf86-input-wacom driver ** 9) I then replayed the event and the stroke was played correctly and it was smooth. Note : please try to make the stroke in one rapid movement across the screen Attached evemu logs pen.evemu -> libinput pen-wacom.evemu -> xf86-input-wacom</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
