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

Nvidia or Intel GPU?
Look at the drivers and make sure a secondary display is available.
What’s your graphics driver?
I don’t have a 470 in front of me. Did you push the “external display” function key combo or configure it in your desktop environment?
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.
Thank you all for theanswerds im new into this, so i will find out what graphics driver i have. Brb
Which Desktop Environment are you using?
Did you install from Minimal or Everything isos?
You may need to install the firmware for the GPU if so.
I have an atomic variant of fedora 40 (Aurora) and it just works on an Intel CPU with integrated graphics. I have a USB c dongle with HDMI out and it just works when I plug it in.
I also tried it on my steam deck dock the other day and it worked without issue.
That’s quite strange. If you plug in a live USB, does it work with other distros? Does your system have an Nvidia GPU?
