After new setup of Linux Mint 19 Cinnamon on 2 Lenovo Thinkpad X-220 I found one with "black" internal monitor.
One machine is working fine. The second has a problem.
On this second machine an external monitor is working fine, The output signal of the internal monitor (LVDS-1) is displayed as well on the external monitor (VGA-1), leaving the internal monitor blank/black.
Hardware should be ok. Monitor switches on/off, backlight is working.
Bios settings of both machines are equal, I had removed the batterie as well as the BIOS backup batterie.

Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192
LVDS-1 connected (normal left inverted right x axis y axis)
VGA-1 connected primary 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm
I guess i need to arrange swapping the output signal (LVDS-1) from VGA-1 plug to the internal monitor plug.
Does anyone have any idea how to?
