I think antiX would be a nice option. I installed it on a 20 years old laptop and it runs quite fast.

I mean, if you are already on openSUSE, why not just use Leap? You won’t need to update it a lot hence you won’t need to reboot.

Yes, basically pretty much everything you may want is possible. OP just uses the bar in floating mode.

As for the age of your laptop, it’s perfectly fine. I still use one from 2011 and it’s doing great.

However if this is your only computer, don’t risk it until the USB ports are fixed. Someone already mentioned but if you have an SD card slot, it might be your way out. Backup your files that way and you can upgrade with peace in mind. Though there is even a newer version now so it’s better to fresh install rather than upgrade twice. After you move your files somewhere else, you can use an SD card to install Linux as well.

We also need a native Wayland client for Steam, though it’s tied to Chromium Embedded Framework’s native Wayland support. Probably it will come with Electron’s support. No idea when.

Sure, I can do that.

• If you’re looking for something lightweight, go for st or urxvt. These are Xorg-only.
• If you want to configure it via GUI, xfce4-terminal is the middle ground for lightweight and feature-rich. If you are on KDE, konsole would suffice. You can use these on Xorg and Wayland.
• If you want to work with multiple panes in a single window, terminator is your friend. Used this on Xorg but not sure about its Wayland compatibility.
• If you want GPU acceleration and more features, kitty and alacritty is out there. Both should work on Xorg and Wayland.
• If you want something like st but pure Wayland, foot is the best lightweight terminal emulator. My current personal favourite.

If you’re occasionally using them, there aren’t any.

If you’re excessively using them, there are many.
