However, upon reboot, Ubuntu displayed my driver settings as using a "manually installed driver", and won't let me change it: When the external display problem first arose, my initial attempt was to switch back to the open source Xorg drivers. I have an nvidia graphics card, and before the update I was using proprietary drivers. There is a monitor plugged in and ready for use, and nothing I do seems to cause it to be detected. My main concern is the final line: HDMI-1-1 disconnected. HDMI-1-1 disconnected (normal left inverted right x axis y axis)
Even when plugged in, the "detect displays" button within the default settings app doesn't do anything. I mean, the external monitor is recognized correctly and all that, but it says there’s “no signal” from the HDMI cable.After upgrading to Ubuntu 18.04, my laptop has been unable to detect/use an external monitor attached via HDMI. The fact is that it actually works, sort of. Every Linux distro out there should work out of the box when connecting it to an external monitor. In the next paragraphs, I’m gonna show you how to properly connect your laptop to an external monitor, and the instructions should work on any Linux distro.įirst, let me tell you that this should not happen at all. So if you’re like me, you’ve arrived at right place. I spent many hours reading these reports and the solutions offered by other users, but with no success. I have recently replaced my old laptop with a new one that’s also great for gaming, so if I want to connect it to an external monitor via HDMI it doesn’t work out-of-the-box with any Linux distro that I’ve tried so far, and if you search the Web for an answer you’ll find numerous reports from users having a so-called “No Signal” issue. A simple tutorial to show you how easy is to connect your laptop to an external monitor through an HDMI cable on any Linux distro if you want to use a second screen for gaming or whatnot, which fixes the notorious “no signal” issue.
