I am using a Lenovo Thinkbook 14 Laptop with a MX450 graphic card. I installed Ubuntu 20.04.1 alongside Window 10. Ubuntu does not detect HDMI display while it works fine on Windows 10. I have tryed various versions of drivers from 435 to 455. None of them worked.
After I ran xrandr in terminal, I saw the below.
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected primary 1920x1080+0+0 0mm x 0mm
1920 x 1080 77.00*
nvidia bug report is attached.
