Thanks a lot for the pointers. I didn't know about it, but something
like reMarkable is what I'm looking for, a device that serves as a
substitute for printed paper in A4 and reading on a desktop screen. The
Parabola hack looks pretty cool (that's supposed to be equivalent to
being able to use Emacs with pdf-tools package). I have seen that the
Wi-Fi does not work (it is not essential for me) but the OTG does. I
will investigate about it... In that device line I had also seen the
Onyx Boox Note. But recently I read that this brand has a sad history of
violating the Linux kernel GPL license.
N.B.: I have to say that I have never used an e-ink device. The
''closest'' thing is this hack I wrote, for use especially on my old
Thinkpad in high light environments. It uses Picom compositor and
Redshift. And, after messing around with the parameters a lot, I found
these that I'm quite satisfied with. It also helps to apply a monochrome
theme in Emacs. Of course, it is nothing more than a simulation to try
to reduce the light emission as much as possible:
#+begin_src emacs-lisp
(setq picom-command "picom --backend glx --glx-fshader-win \"uniform sampler2D
tex; uniform float opacity; void main() { vec4 color = texture2D(tex,
gl_TexCoord[0].xy); gl_FragColor = vec4(vec3(0.2126 * color.r + 0.7152 *
color.g + 0.0722 * color.b) * opacity, color.a * opacity); }\"")
(setq redshift-command "redshift -l 40.5914000:-4.1474000 -b 0.9:0.9 -t
4000k:4000k -g 0.5:0.5:0.8")
(defun my-poor-man-eink-toggle ()
(interactive)
(when (equal (process-status "picom") 'run)
(kill-process "picom"))
(if (and (not (equal (process-status "picom-g") 'run))
(not (equal (process-status "redshifg-g") 'run)))
(progn
(shell-command "killall picom")
(shell-command "killall redshift-gtk")
(shell-command "redshift -x")
(start-process-shell-command "redshift-g" nil redshift-command)
(start-process-shell-command "picom-g" nil picom-command))
(kill-process "picom-g")
(kill-process "redshift-g")
(shell-command "redshift -x")
(start-process-shell-command "redshift" nil "redshift-gtk -c
~/.redshift.conf")))
