I do need some help, advice. I was unable to find error log, if there exists any. Thus no debug information. Maybe You could help me narrow what is wrong in my configuration.
Problem is that moving mouse cursor to position not always (sometimes it works normally, but mostly not) trigger action. Like highlight user (or button), allowing it to be selected in gdm. Or in gnome 3 when logged in.
My desktop has two seats (configured with loginctl, out-of-the-box) and it happens only on seat2. I tried switching mouses, and usb ports. No result. Works on seat0 and not on seat2 independent from input hardware.
Seat0 is using nvidia card. Seat2 has intel (on board) display.
X configuration is auto created. (with exception to nvidia modules and driver)
ps -Af|grep X

When one logs to other than gnome window manager (like XFCE) no mouse problems are observed on seat2
Any hints and ideas are mostly welcomed.
