I'm looking forward into contributing to other system based on bootc referring to my experience. Reach out to me if you want to maintain this system: https://jill.rip/contact\n\n# Cosmium [WIP]\n\n![Screenshot of Live ISO environment of Cosmium showing an opened window of Examine app and Welcome dialog](.github/imgs/screenshot-about.png)\n\nNote: to test it out on QEMU/Virt-manager, switch display input from Virtio to QXL. (not exclusive to Cosmium)\n\nLatest Live ISO builds:\n- **Stable**: https://github.com/Cosmium-OS/Cosmium/actions/workflows/build-iso-live.yml?query=is%3Asuccess\n- **Testing**: https://github.com/Cosmium-OS/Cosmium/actions/workflows/build-iso-live-testing.yml?query=is%3Asuccess\n\nGrab the latest successful artifact for either Desktop or Gaming Handheld Edition (`cosmium` or `cosmium-deck`). To download an artifact without logging in to GitHub, you can replace `github.com` to `nightly.link` in URL. No matter for how long those ISOs wasn't updated, you can still perform an update by running `sudo bootc update` no matter what. New builds would be triggered when it is appropriate to do so (like changing branding, new flatpak apps, fixes to Live ISO environment, etc). We're using Universal Blue's [titanoboa](https://github.com/ublue-os/titanoboa) to make this happen :).\n\nTODO: \n- [ ] (Re-)rewrite this file\n- [x] Fix timezone weirdness on Live ISO environment (it fixed itself apparently)\n- [x] Change favorite apps on dock for Live ISO environment\n- [ ] COSMIC focuses on Steam Keyboard, making it impossible to type from Steam Deck, maybe enable on-screen keyboard that is compatible with COSMIC? (presense on Gaming Handheld Edition)\n- [x] Remove COSMIC Store and replace it with configured Bazaar (~~we already have both installed,~~ Bazaar is still not configured)\n- [x] Fix switching to desktop mode on Gaming Handheld Edition\n- [ ] Fix switching back to gaming more (reboot will do the trick for now)\n- [x] Enable auto-login to Steam Gaming Mode on Gaming Handheld Edition\n- [ ] Switch to Anaconda WebUI when it is stable enough\n- [ ] Add more third-party themes to the system and maybe even widgets\n- [x] Switch to own underlying image of Fedora COSMIC Atomic ~~when Universal Blue will [deprecated it](https://github.com/ublue-os/main/issues/927)~~ ([`cosmic-atomic-custom`](https://github.com/Cosmium-OS/cosmic-atomic-custom), do it like Winblues does)\n- [x] Add Nvidia-open variants\n- [ ] Do a proper branding\n- [x] ~~Figure out secure boot and kernel signing~~\n- [ ] Turn off compiling akmods for no reason in Live ISO env\n\nThanks to https://github.com/askpng/solarpowered for providing some hack that was previously used for installing Bazzite kernel!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcosmium-os%2Fcosmium","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcosmium-os%2Fcosmium","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcosmium-os%2Fcosmium/lists"}
