Ebook-viewer does not work with Ubuntu 22.04 Wayland [6.13]

noodler · 02-23-2023, 05:22 AM

The ebook-viewer works normally in Ubuntu 22.04.02 LTS with X11 but if I switch to Wayland, the ebook-viewer does not launch properly:

- it appears in the task bar but no window is created.
- the auto-preview in the task bar says "loading b..."
- doesn't matter which book is opened
- The application cannot be closed and the underlying process must be killed.
- Same behaviour whether launched from within Calibre, from a file browser or from the command line
- I see no messages at the command line or in syslog
- also applies to the ebook-editor
- the main Calibre application runs ok
- applies to Calibre 6.13 installed using suggested script not from the Ubuntu Snap Store

Unfortunately, Calibre once again refuses to adapt to modern standards, and until it does so, you are going to need to hack things.

First, try launching it as such:

```
QT_QPA_PLATFORM=xcb calibre
```
If the viewer works fine there, proceed with the following -

Run the following to get the full path to the executable. That is /usr/bin/calibre on my system.

```
command -v calibre
```

Then create /usr/local/bin/calibre with the following content:

```
#!/bin/bash

QT_QPA_PLATFORM=xcb /usr/bin/calibre "$@"
```

And give it execute permission

```
chmod +x /usr/local/bin/calibre
```

That should be all you need to hijack the executable and force XWayland and have Calibre work correctly again, make sure to remove it when hell freezes over.

Don't confuse unfinished niche new software (Wayland) with "modern standards". MS have thing called a "modern GUI" and it's rubbish.

Calibre works better than many programs on a wide variety of Linux, Mac and Windows.
