You have been subscribed to a public bug: Firstly I'd like to apologize as I am a novice Ubuntu user and I am unsure as to which information I should include within this report.
That being said, I have installed linux 20.04-- my system: cpu: ryzen 9 3900x, gpu: radeon rx6800. Ubuntu is detecting default display at correct resolution, which is connected via DisplayPort on rx6800 gpu. However, my second monitor, LGCX 4k OLED connected via HDMI is not detected in display properties window. xrandr does not detect outputs other than default display. I have run apt-get update and apt-get upgrade, restarted, unplugged and plugged displays back in, tried installing amd-gpu drivers separately which were downloaded from official website, i have tried updating kernal, along with many other troubleshooting strategies. I believe this to be some sort of software issue. ** Affects: xorg (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: amd bot-comment display displayport dp hdmi radeon ubuntu -- Ubuntu does not detect video output devices https://bugs.launchpad.net/bugs/1923318 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
