Ubuntu – Ubuntu 16.04 hides cursor when using graphics tablet

16.04cursorgraphics-tabletinput

For some reason Ubuntu hides the cursor when I'm hovering my stylus above the pad. It works ok when you are in drawing area since it has its own cursor. But it's completely useless when you try to use the UI of the graphics program or the desktop itself. How do I force Ubuntu to keep the cursor visible?

EDIT: I've done some testing and it seems that it is 16.04 specific problem. On my other machine with 15.10 cursor does not hide. This is also not related to nVidia GPU driver or hardware. I have tried on yet another machine with 16.04 but with Intel GPU and cursor hides again.

EDIT2: Running

  gsettings set org.gnome.settings-daemon.plugins.cursor active true
  gsettings set org.gnome.settings-daemon.plugins.cursor active false

in terminal (after cursor gets invisible) causes tablet cursor to work as long as I don't move mouse. When I move mouse even a pixel then tablet cursor gets invisible. Sometimes it disappears randomly and I have to execute these two commands again.

I've finally figured it out. The problem was that my mouse was connected via PS/2 port and my tablet was connected via USB. I've connected my mouse via USB and cursor disappeared permanently. But after system restart everything works perfectly fine. I can control my pointer using both mouse and tablet and nothing disappears anymore. Looks like Xorg can't handle input from PS/2 and USB at the same time.

But Ubuntu 15.10 had no problem with it. Machine with 15.10 on which I've done testing before is a laptop with touchpad connected internally via PS/2 and I was using exactly the same USB tablet. There were no problems on that machine.
