From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Turn tablet into ereader (self.linux)

Just like the title says I want to turn an old tablet of mine into an ereader.

The tablet in question is samsung galaxy tab 3 in which I installed postMarketOS.

I installed the console version, and once everything was set up I ssd into the machine and installed the following packages :

greetd, greetd-openrc, cage, fuse

Downloaded koreader app image into /bin/

Activated the greetd service

rc-update add greetd default

and configured /etc/greetd/config.toml with the following

[terminal]

vt = 1

[default_session]

command="agreety -c sh"
user="greeter"

[initial_session]

command="cage -s -d -- koreader"
user="me"

and rebooted the tablet, however I am still stuck with the login prompt no matter what I do.

Any tips on how fix this or a other way I could accomplish my goal?

Update

Got autologin working by ditching out greetd and using agetty, and a simple fortune command to run on startup.

After this I went for the kill and tried to install KOreader using flatpak, due to App Images not playing alright with Alpine. However I noticed something there is no arm build of KOreader for linux arm so my plans were cut short.

Will try to compile KOreader to linux arm if not successful will just put a nice UI and use the little guy as a portable hacking machine.

New update

KOreader was mess to compile so I looked for alternatives and found out foliate which fits my criteria (opds, epub and pdf support) and is in the alpine repos.

Played around with cage and got the thing somewhat working, however no virtual keyboard support for now, figuring that out now.

Updates I can ssh into the thing since WiFi is working and turn off I use the power button might have to change some devrules because now it's long press is mapped to reboot a single nothing, but that should be about it.

* Yeah cage is an Wayland kiosk, and for what I tested in my main machine runs KOreader with no problem and should have a virtual keyboard.
