I am trying to get my HDMI output on my Dell Precision 7530 working. The USB-C to HDMI adapter works perfectly fine, but the HDMI output on the back does not.
xrandr reports that
What I have tried:
sudo ubuntu-drivers autoinstall
sudo apt-get purge 'nvidia*' sudo add-apt-repository ppa:graphics-drivers sudo apt-get update
prime-selectto switch between Intel and nVidia
During the install at one point I had a wierd thing happen where I had my HDMI monitor outputting the login screen and my laptop and USB-C monitor outputting the Dell boot screen logo. This went away after reboot, and that was the last time my HDMI monitor worked with ubuntu.
What can I do to get it working or am I just done for?
Я исправил это, купив другой адаптер USB C к DVI и используя его вместо выхода HDMI на задней панели. компьютера.
