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"))) #+end_src
