I have a Lenovo Thinkpad E531 running Ubuntu 20. I want to connect two external monitors using the VGA and HDMI connectors on the notebook.
The problem that I am running into is that xrandr won't display more than one external monitor. For more it says:
xrandr: Configure crtc 2 failed
I have tried using the ubuntu displays setting. Tried using xrandr and arandr. I tried setting one monitor after the other. I tried different settings with xrandr.
The best I got was the two external monitors mirroring and extending the laptop screen. Can anyone point me in the direction of the solution.
The output os xrandr --listproviders is:
