[SOLVED] Mouse cursor disappears after resuming from sleep mode

Hi, all

I've been using Xubuntu on an old MacBook3,1 (MB062xx/A). It works rather smoothly, save for the following annoying situation: the mouse cursor disappears after resuming from sleep mode.

Initially, I installed Xubuntu 15.10. After resuming from sleep mode, everything behaved normally. However, since I performed the upgrade to 16.04, the cursor started disappearing after resuming. Sometimes it appears after opening and closing a few windows, but most of the time doesn't, and I have to reboot in order to have it displayed again. The cursor is still there, since I can move it, launch applications, etc. However, it's not displayed.

Just in case, here is the output of uname -a:

Linux ramiro-MacBook 4.4.0-22-generic #40-Ubuntu SMP Thu May 12 22:03:46 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Any ideas?
