Mouse pointer not displayed unless mouse attached

[NeilGreenwood]

I have an Ubuntu machine that is running synergyc. I connect it to a Windows 7 synergy server.

After a reboot, there is no mouse pointer displayed when I move the mouse in the appropriate direction from the synergy server. I can see buttons display their mouse-over animation, launcher icons display their tooltips, and I can click all widgets (although clicking the intended one is difficult).

Without logging off, I connected a mouse. The pointer was displayed. I disconnected the mouse, and the pointer remained, even responding correctly to the synergy mouse events.

I saw the expected behaviour before upgrading to saucy.

[Brad Larson (bklarson)]

I just upgraded to 13.10 today and have the same issue. This wasn't a problem with 13.04. Running `gsettings set org.gnome.settings-daemon.plugins.cursor active false` fixed it for me (from http://synergy-foss.org/osqa/questions/3148/ubuntu-1310-no-cursor-visable-with-synergyc)

[Yura (ykuchinskiy)]

I confirm that workaround from post #3 fixed the problem for me (ubuntu 15.04)
