Terminal emulator kitty

Hardware Librem 5
1

My 15 years old son (a Linux nerd) uses on his desktop the terminal emulator kitty which seems to do nicely with Unicode codepoints, to select them from menus. I have to ask him for a screenshot…
That’s why I installed it in my L5:

$ sudo apt install kitty

$ apt info kitty

But it is unwilling to start from kgx:

$ kitty

Any ideas?

Does it do HP terminal emulation? (As opposed to VT100 or IBM3270?)

I was able get kitty running on my L5 by forcing CPU-rendering. This was the command:

LIBGL_ALWAYS_SOFTWARE=true kitty

Unfortunately, the results were less than ideal. Kitty runs, but it runs rrrreeeeeeaaaaaal slow.

I hope/imagine that this will change once we start seeing some updates on this front, but I truly don’t know.

Thanks, but with this it gives SIG_SEGV before showing anything.

Yes, the same in Crimson with backports and no effect from version_override variable :frowning: .

Sure, because the situation is the same for every L5 system. Once the Kernel has an update with GLES3, you will recognize it by GPU-thread activities.

Just gotta say… Terminal Emulator Kitty would be an awesome band name! Lol!

Good question.

As far as I can see from the available documentation, it is bizarrely completely silent on this question. I would tentatively conclude from that silence that it is “VT100” only, presumably heavily extended. So my guess is no dice for you. :wink:

Thanks! The “big” terminal emulator (Reflection) always had a config choice as to which kind of terminal you want to emulate. HP was leaned heavily on escape sequences for screen control, whereas VT100 used control characters.
