Calibre ChromeOS SDcard

Quoth · 02-05-2025, 08:19 PM

I've installed Calibre, KATE and LibreOffice on a recent model x86-64 (AKA AMD64) using the enabled Linux Development system which is some sort of Debian based Container. I had to set a password for the user because the default "password-less" sudo makes no sense

Calibre setup works with the default Linux user's home, but vanishes after initialising.
Running from command line I get some sort of wayland error "Screen5" screen model: "unknown"

But QT_QPLATFORM=xcb calibre worked and then I was able to move library to the SD card (which I couldn't choose at install)
Doing export QT_QPLATFORM=xcb in terminal works for subsequent calibre in terminal, but not from Launcher icon.
I can't figure where to put the setting so the Launcher icon works.
Trying to edit the desktop file used by Launcher didn't work but maybe I did it wrong.

On my chromebook I modified the desktop launcher file. I use the following script

Code:

#!/usr/bin/sh
#

cp /usr/share/applications/calibre*.desktop .

for file in calibre-gui calibre-ebook-edit calibre-ebook-viewer calibre-lrfviewer ; do
        echo Editing ${file}.desktop
        sed -i -e 's/^Exec=/Exec=env QT_QPA_PLATFORM=xcb /g' ${file}.desktop
        echo Installing ${file}.desktop
        sudo desktop-file-install ${file}.desktop
done

I run this script after each install and upgrade of calibre.

Typo it's QT_QPA_PLATFORM

Edit I've added a file in /etc/environment.d

That works and won't be overwritten

I got the cute 11.5" Galaxy Go as a present. Much better than the old netbooks or older Chromebooks

However it's baffling that the native OS is really Gentoo, yet they have the complex layers of stuff and a container called penguin that runs Debian.
The way "shared to Linux" stuff is done is a bit mad too. However I got the microSD card (with ext4) also availble to Linux as the SSD or whatever is only 64 G (still the early Netbooks only had 4G, and slow!)

An Appimage of LibreOffice didn't work but sudo apt install LibreOffice was fine.
