I have a new MSI GE76 Raider laptop with fresh installed Ubuntu 18.04 and upgraded to Ubuntu 20.04.
After installed Nvidia drivers v470.86 on Ubuntu 18.04, the system can’t detect the internal display. The GUI only worked on the external monitor. The internal display can only be switched on with CTRL + ALT + F5 hot-key(the external display is OFF, when the internal display on console)
The following post suggested the kernel is too old to support the Intel iGPU, so I upgraded it to Ubuntu 20.04
So far, it only detect the external monitor, not the internal display.
lcpci shows 2 VGA devices
$ lspci |grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Device 9a60 (rev 01)
