Binary package hint: xorg
It happens intermittent and was seen on different kernel-versions. I can't remember if the version of any xorg-package changed.
It's like the pointer on the screen is transparent or has a size of zero - it's not visible. But it's there (for the software) as i can blind use the pad to try to hit an item (link in browser, window to activate, ...), which will work as expected. But it's hard to do something useful in the xsession.
The touchpad gets recognized by the kernel and Xorg-server, according to the logs. A reboot (no powerdown) will fix this issue, till the next time.
I tested that it will not be fixed by restarting the Xserver. This time it happend again after rebooting the PC, but I think rebooting someone fixed it.

Sometimes after the screensaver, the mouse pointer becomes invisible on a current to 11/6 Maverick 10.10 system. I am running the Nvidia graphics 6150, without the proprietary drivers. I don't recall seeing this problem in any earlier release. The hardware did not have problems with the 10.04 black screen of death. Going to a virtual terminal and returning did not restore the pointer. I usually just reboot.
