From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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 have a 470 in front of me. Did you push the “external display” function key combo or configure it in your desktop environment?
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?
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.
That's quite strange. If you plug in a live USB, does it work with other distros? Does your system have an Nvidia GPU?
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.
Did you install from Minimal or Everything isos?
You may need to install the firmware for the GPU if so.
