Hey. Well I’ve got a thinkpad running with fedora 40. I wanted to plug the TV in, with HDMI, but nothing happened. So how do I activate it? Its a Lenovo T470
EDIT: i found it out. Thank you for the help.
HDMI should work out of the box.
GPU info needed
Look at the drivers and make sure a secondary display is available.
What’s your graphics driver?
Nvidia or Intel GPU?
I don’t know specifically about the T470, but if you have an nvidia GPU, you might have issues depending on how the display outputs are connected to the GPUs. I had a T420s at some point with an nvidia GPU, and it was a PITA to get the display output to work on linux. I had to permanently enable the nvidia GPU for that to work (cutting battery life in half), because the display output was connected only to the nvidia GPU. I swore to never buy an nvidia product ever again after that experience.
