Hello all
I have installed "Xubuntu 16.04, Xenial Xerus" on a new Lenovo T560. Everything works exactly as expected with the exception of the following:
When I lock the laptop, using the using "Lock Screen" icon in the menu, and then unlock it again, the mouse pointer disappears.
The mouse is still functional. It is possible to click on the icons in the panel, for example, however, the mouse pointer is invisible.
I experience the identical behavior after waking up from hibernation too.
When logging in for the first time, or after logging out, the problem does not occur.
As a workaround, I can switch TTY with:
Ctrl + Alt + F1
Ctrl + Alt + F7
And the mouse pointer magically re-appears.
Besides this workaround, is there a fix to the problem?
Here is the output of "lcpci", showing the hardware in the laptop:
