I have a thinkpad T480 with LMDE and up until about two months ago it would work with this Samsung commercial display TV, although it never played audio from the TV like it was supposed to.

Now when I plug in the HDMI cable the screen turns black (not blue, which is when there's no signal). If I go into display it shows that the TV is connected.

I know that this isn't a hardware issue because I've used the same HDMI cable and laptop on a different TV and it worked fine. xrandr also says that HDMI-2 is connected.

The journalctl command returns [UFW BLOCK] IN=wlp3s0 OUT=(long string of numbers)

did it have some sort of error or failure? if it did, are you able to copy/paste several lines before and afterwards?

This output is just for the network firewall.
In this case, you might want to ignore all messages with this pattern.

Perhaps look into other messages

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.
