I'm trying to ditch Windows for good, but I've been struggling to get my CAC card to work reliably in any browser or application on Linux. I had it functioning fine in Chrome for a bit, but then it just stopped working last week. The settings in browsers aren't very intuitive when it comes to configuring these. Has anyone managed to use a CAC card successfully on Linux? Any tips?

I tried that too, but the tutorial seems super outdated. I ended up hunting for information across different sources to make it work.
Just wanted to update: I figured out that Wayland was actually messing things up. The popup for entering my PIN wouldn’t show. I ran Chrome in X11 instead using this command: --ozone-platform=x11 %U. Also, if you're having issues with card readers, Chrome is your best bet. Firefox didn't work for me, and I downloaded Chrome directly from their site to avoid sandboxing issues.
What exactly is a CAC card? Did you mean something like a capture card? If it's a capture card, check if it supports the UVC protocol because many other drivers are proprietary and not Linux-friendly.
Yeah, it's a type of ID card used in the military that has an embedded smart chip.
Did you check out the guide on their website about using CAC cards? It might help! Setting up the software can be a bit tricky and varies based on your Linux distro, though.
A CAC card refers to a Common Access Card, which is primarily used by the US military as a smart ID card.
