Empty main screen when i upgraded to Ubuntu 22.04

[Axiome]

So after i upgraded to 22.04 yesterday , anki is no longer showing the main window , so i can’t find review my cards
i am using anki 2.1.50 qt5
on ubuntu 22.04 , wayland (is the default)

ps : it works fine on anki 2.1.51 qt6 but not on 2.1.51 qt 5 (i tested them both on ubuntu 22.04)

The --no-sandbox flag will probably fix this:

Anki shows a blank window

You could create a shell script to start Anki with the --no-sandbox flag: #!/bin/bash export QT_QPA_PLATFORM=xcb anki --no-sandbox QT_QPA_PLATFORM=xcb prevents Anki from running in Wayland. That’s optional of course, but I recommend it because Wayland isn’t a good experience yet.

Also, Wayland has some issues, so I recommend using x11 (xcb) for now.

it worked , thank you
the problem is that , taking x11 as “a default windowing system” is no longer an option on this latest version of ubuntu where wayland is the main

anyway it is working well now , thx again

The text @kleinerpirat quoted describes how to tell Anki to use X11/xwayland - it doesn’t require you to start an X11 session yourself.
