How to solve this problem
It’s installed via a Decky plugin. Open the Quick Access Menu in Steam Gaming Mode and uninstall it.
If you’re in Desktop mode, the ‘Official’ instructions to uninstall SimpleDeckyTDP found on it’s github page are as follows:
sudo rm -rf $HOME/homebrew/plugins/SimpleDeckyTDP
sudo systemctl restart plugin_loader.service
Thanks. It works fine now. But after closing Steam, the buttons can’t be simulated properly. How can I make it work properly under KDE Desktop?
Thanks, it works fine now
