Sorry for the delay in replying.
Thanks for the informative link!
I'm really against pursuing any new design dependencies on X,
so even "or similar" sounds iffy to me. Just IMO ;-)
I recognize it will be a while before we can ignore X-based apps, but we can
stop
using it as GUI infrastructure, if Wayland can provide GUI foundation with
Xwayland
giving X apps a path to the screen via Wayland. Of course Wayland has
dependencies
on what the kernel can provide, like libdrm stuff.
Wayland seems a likely X successor, and represents an
opportunity to do GUI without X dependencies, for a cleaner Guix.
I can report that tilix as implemented in PureOS on a Librem13v4 provides
a workable GUI solution for multiple keyboards, even if it's not what I had in
mind ;-)
Here is an overview:
PureOS is debian-based Purism variant with gnome for desktop etc and I think
all composited and displayed by their Wayland, providing xwayland only as a
service for apps needing the X interface, but not itself depending on X.
tilix is, I think, a pure wayland client implementation, and can provide
multiple simultaneous terminal tiles on the screen, overlapping or not.
These window tiles are created by typing "tilix" with optional args.
Without args it creates a new tile space according to a Default "profile"
which you can do a LOT with, but don't need to to demo the keyboard mappings.
The first tilix command will normally be typed into a widget that comes up
on pressing the super key (some keyboards will have a windows flag on that key
:).
Subsequent tilix commands can be typed in any tilix terminal, and will produce
another
terminal tile accordin to parameters in the profile (of which you can create
different versions).
Choosing a keyboard language (separate dropdown widget at top of screen) in any
of these terminal tiles that has focus will set the keyboard mapping for that
terminal
tile only. Switching focus to another tile will use the the kb mapping chosen
for it.
Persistence is attached to the terminal tile.
So you could have two different language keyboards plugged in and use one to
type
into one tile terminal and the other for the other. You just have to switch
focus
to where you want the typing to appear.
But this is also a kind of illusion, because both keyboards' untranslated
keycodes
are apparently merged into the same stream and fed where the focus is.
So you can't mix languages on one terminal tile by just typing on the alternate
keyboard
(as I had wanted)-- you have to go to the language choice widget and
temporarily switch
there, no matter which keyboard you are typing on.
Some keys are obviously the same, so it doesn't matter which keyboard you type
those on.
It goes to the focused tile and gets translated, but the mapping
for those keys is the same.
Right now I am in GUI emacs called as editor for mutt, and the language
selection has no effect
even though when I exit all the way back to the bash where I typed mutt, it
will (or should ;).
pidparents ? 18587 Ss /usr/bin/bash /home/bokr/bin/pidparents
emacs pts/0 18069 Sl+ emacs
/home/bokr/.mutt/temp/mutt-LionPure-1000-17715-4020479191039126306
sh pts/0 18068 S+ sh -c emacs
'/home/bokr/.mutt/temp/mutt-LionPure-1000-17715-4020479191039126306'
mutt pts/0 17715 S+ mutt
bash pts/0 13623 Ss /bin/bash
tilix ? 13618 Sl /usr/bin/tilix --gapplication-service
systemd ? 1644 Ss /lib/systemd/systemd --user
systemd ? 1 Ss /sbin/init splash
And if I were at the tty initial console, the widget for language change
wouldn't be there, since no gnome GUI.
I would have to use loadkeys. And back in grub, another world. And back in the
BIOS, another.
And all considerations repeated for booting from external disks, net, whatever.
Phooey ;-)
There's gotta be a better way :)
That "joke" enthusing about a Mach microkernel sounded good :)
