Public bug reported:
Hello. I have a laptop Lenovo Legion Y540-15IRH (81SX00EVRA) with Hybrid
graphics.
OS: 20.04.4 LTS and Windows 10 in dual boot.
BIOS is set to Switchable Graphics, meaning Hybrid.
NVidia PRIME profile is set to Intel (power saving).
So the problem is that on Ubuntu system doesn't detect an external monitor
through HDMI port.
When PRIME profile was set to NVidia best Performance - it was able to detect
the external monitor.
But as I am not playing games anymore - I don't want to use power-consuming and
noisy discrete RTX 2060. So I switched to integrated Intel UHD Graphics 630.
What should I do in order OS to detect an external monitor?
Thanks
