I know there are people who use startplasma to launch the Plasma Desktop by hand (since it's a supported method to launch Plasma Wayland). Does that also fail with kmscon? If so, does that mean we need wrappers to ensure people don't have to figure this out? I don't think the kmscon-launch-gui command is ergonomic or discoverable, so we probably need to adapt things instead. -- 真実はいつも一つ！/ Always, there's only one truth! -- _______________________________________________ devel mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
