mouse pointer disappear after screen off

[Hans P. Möller]

With nouveau driver (doesn't happened with propietary nvidia) after screen switch off because of power management, the mouse pointer disappear. Mouse still works, you can hover, select, click, but the pointer is invisible.

In a dual monitor configuration, this only happened in the screen where the mouse was when it turned off. If It firs happened in one monitor and tehn I left the mouse in the other and it also turn off, mouse end up disappearing in both.

My video card is an nvidia GeForce Go6150 (NV4E C51).

Hi,
  I've seen this problem since I install linux in this computer (2 years ago), but my workaround was to use the nvidia propietary driver. Now that nvidia stop developing the 304 driver, I will have to use nouveau.
I installed 4.17.0-041700rc7-generic and the problem still is there. It might be that I had to wait a couple of minutes more oafter the screen switch off or suspended, but the problem is still there.

I just realize that it only happen after login (lxde, lubuntu) in lightdm this does not happen.

Do you see the same issue under different DE (Unity/Gnome/KDE)?

[Hans P. Möller (hmollercl)]

I haven't tried with other DE, since it is an old computer I have only tried lxde. I could easily try with openbox alone, installing another DE could be a little longer. Is there one better to test with?
