Screen resolution change with Suspend

Hi,

I have noticed that the screen size change when the pc switch in suspend mode.
The size appear to be about 800x600, but my screen is normally at 1920x1080.

DVI-D-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
   1920x1080     60.00*+  59.94    50.00    60.05    60.00    50.04  
   1680x1050     59.95

   720x480       59.94  
   640x480       75.00    59.94    59.93

:~$ lspci | grep -i --color 'vga\|3d\|2d'
09:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 3GB] (rev a1)

I have seen that there also one display manager called LightDM but I dont know if this is responsible for that issue.
Here how the pic with 800x600

Re: Screen resolution change with Suspend

Possibly this bug with light-locker and the nvidia driver?

Re: Screen resolution change with Suspend

As I read, the bug appear (if this is a nvidia's bug),  not resolved.
