This merge requests adds a few enhancements:

CNB-Kevin commented 4 years ago

There is an issue where if you turn off the driver (I run it in a terminal and use ctrl+C while I'm testing things) if multi-cursor is enabled (which it is by default). Leftover cursors can stay on screen or appear/disappear.

It could be user error on my part because I turn it off, but it's also caused by the lack of cleanup at the end of the program, which is also a thing on the main branch.

pmetras commented 4 years ago

Yes, multi-cursor on X is not reliable. There a bit of cleanup in the code when the driver is started again but it would be better to do it at the end of program, if there were a cleanup procedure before exiting.

pmetras commented 4 years ago

I finally had the opportunity to test the clean up code for multi-cursor (the tablet is 6000 km from my computer!). Leftover cursors when the driver is interrupted shouldn't remain on the screen and X should be more stable now.

hey! first of all thank you for this miracle! everything is ok except i still have the residual pointers in my tablet. also while drawing i get a round semi transparent box around the cursor. and i have two residuals cursors on my tablet after i end the script that keep flickering. aaand while it works there is always one inactive cursor on the side of the tablet. so i have one moving with the mouse.one with the pen and one that just sits there. also even if i set multi cursor to false its still enabled oh sorry 18.04 version!

My daughter who owns the tablet told me she has the same behaviour from time to time. She told me that there could be a conflict with Firefox too but I don't have the details. And I can't debug, only when I go and visit my daughter far from home... The multi-pointer part is really a hack. I hope a temporary one before we have a better driver.

i see well even like that its still great!! but.. sorry really. i upgraded to 20.04 and i have this issue while running the code.would you happen to have any ideas as to why??i'll try to take a look at it tomorow since its past midnight here but i was just wondering!the problem is that the pointer is not directly folowing the pen unless i reach the far right of the screen. Screenshot from 2020-04-25 00-31-33 edit: it coudl just needed a reboot as now it works flawless . i did change the display settings using LXRandR but i dont know if its a coincidense! in any case i'll look into it a bit more tomorow

Could it be that the calibration of the tablet is not correct? Or perhaps this pull request https://github.com/joseluis/huion-linux-drivers/pull/62 is correcting your issue?
