Returning to Linux After a Long Break: What Should I Know?

Debian has made significant strides, releasing new stable versions every two years, with the latest just out recently. If you're looking for newer software, you can explore the backports repository, which helps bring newer packages to a stable environment without too much hassle.

When it comes to using 4K displays with a KVM switch, if it's a good switch, you shouldn't have any issues. Just ensure that your graphics card and drivers are up to the task. For some cheaper KVMs, you may need to employ some workarounds for them to function properly with Linux, especially for resolutions like 4K.

For syncing files like OneDrive, you might like Syncthing, which syncs folders across devices directly without a central server. It keeps things peer-to-peer and is relatively easy to set up, especially for local backups or across your own devices.

Ubuntu promotes Snap packages more than Debian does, which still solidly relies on APT. Some APT packages in Ubuntu now redirect to Snap installs, but Debian remains a pure APT distro if you prefer that. It's really about which ecosystem you're comfortable jumping into.

When looking for pre-built towers, make sure to check the WiFi card specifications explicitly. While most hardware works well on Linux, laptops are more hit-or-miss. However, desktops generally have good support. For graphics cards, AMD has really improved with open-source drivers, while NVIDIA remains proprietary, so consider that when making your choice.

MTP support can vary, so it's hit-or-miss. Most desktop environments have MTP working out of the box, so you can plug in your phone and it should show up. However, I'd recommend checking out KDE Connect; it often offers a smoother experience for transferring files over WiFi instead of USB.
