Can't make the date?
If you come to this page before or after the test day is completed, your testing is still valuable, and you can use the information on this page to test, file any bugs you find at Bugzilla, and add your results to the results section. If this page is more than a month old when you arrive here, please check the current schedule and see if a similar but more recent Test Day is planned or has already happened.

What to test?[edit]

This Test Day will focus on the desktop backgrounds / wallpapers shipped in Fedora 36. There are two main sets of backgrounds we'd like tested:

  • The default Fedora 36 background - we did not make the beta media so we'd like folks to test the background and note their monitor(s) and resolution(s) and desktop environments(s) to ensure it looks acceptable. The "fedora" text logo in the lower right corner (under GNOME) should be visible. Users of the GNOME desktop will also have the opportunity to test the new "dark mode" feature which this wallpaper supports.

  • The extra wallpapers included by default with Fedora 36 - these also did not make the meta media. There is a set of 12 installed-by-default but not set as default wallpapers that will ship with Fedora 36. 6 of these are abstract wallpapers provided by GNOME upstream, and 6 are Fedora community submitted photographic wallpapers. All of this set of 12 wallpapers supports the new dark mode in Fedora Workstation / GNOME. we'd also like folks to test these backgrounds and note their monitor(s) and resolution(s) and desktop environments(s) to ensure it looks acceptable.

Who's available[edit]

The following cast of characters will be available testing, workarounds, bug fixes, and general discussion:


You can chat with us on the Fedora Design channel on fedora.im https://matrix.to/#/#design:fedoraproject.org. See the infobox on top of the page to learn the right IRC channel.

Máirín Duffy (mizmo) and Madeline Peck (madelinepeck) will have live office hours from 1700-1800 UTC (1-2 PM US Eastern Time) during this test day in the Fedora Design Matrix channel accessible via this link https://matrix.to/#/#design:fedoraproject.org or via the IRC link at the top of this page.

Prerequisite for Test Day[edit]

  • A virtual machine or a bare metal machine
  • An installation of a recent Fedora 36 Nightly (any Edition or Spin). Make sure to fully update your system. If installing a fresh system, it's recommended to use the latest nightly image. The nightly images *should* have all of the updated wallpapers in needed of testing by the test day - the March 28, 2022 nightly was tested and did indeed have them.

How to test?[edit]

This isn't too intensive a test process. We need your help trying out these wallpapers using your desktop environment of choice with your monitor / resolution to simply make sure they look OK. For those using GNOME, we'd like you to test both the light and dark modes of the wallpapers.

Please note your monitor resolution and the desktop environment you are testing the wallpapers under.

Log your results on our event's page on the test days app: https://testdays.fedoraproject.org/events/130

Things to look for depending on the wallpaper you're viewing:

The default Fedora 36 background[edit]

  • The "fedora" text logo in the lower right corner (under GNOME) should be visible and readable.
  • Users of the GNOME desktop should be able to enable "dark mode" and "light mode" on this wallpaper and test both versions.
  • When set as the active wallpaper, the wallpaper should not hurt your eyes or be overly distracting as you engage with the desktop.


The extra wallpapers included by default with Fedora 36[edit]

  • Users of the GNOME desktop should be able to enable "dark mode" and "light mode" each of these 12 wallpapers and test both versions.
  • When set as the active wallpaper, the wallpaper should not hurt your eyes or be overly distracting as you engage with the desktop.

Please also try to experiment and explore and perform tasks not mentioned in any of the pre-defined test cases. If anything stands out to you as something that appears wrong or broken about the wallpapers, please report it.

Reporting bugs[edit]

Bugs with the Default Wallpaper[edit]

Bugs related to the default wallpaper should be reported into Bugzilla, in most cases against the f36-backgrounds component.

Bugs with the Fedora 6 photographic extra backgrounds[edit]

Bugs related to the photographic extra wallpapers should be reported into Bugzilla, in most cases against the fedora-workstation-backgrounds component.

Bugs with the GNOME 6 abstract extra backgrounds[edit]

Bugs related to the abstract extra wallpapers should be reported into Bugzilla, in most cases against the gnome-backgrounds component.

If you are unsure about exactly how to file the report or what other information to include, just ask us on IRC / Matrix (see instructions above).

Test Results[edit]

Test results will be exported here once the test day is over. See How to test? section for information how to submit results and see the live results.

For some reason I can't load these into the test days app right now so -

Installer ran fine, sshd in, and no ip address was reported on screen. got the ip address from virt-manager and ssh'd in. Seems to be working, tried machinectl shell to open standard user from ignition file, worked fine.
  3. started live cd install using virt-manager. Started ok, to prompt, but when trying to run coreos-installer picking up config.ign from the local network, the install failed with 'error checking whether /dev/sda is an ibm dasd disk.' Output of lsblk is garbled, with disk listed as '^%\xef\x9aaU'. Perhaps related to this (https://discussion.fedoraproject.org/t/coreos-pxeboot-coreos-installer-cant-format-dev-vda-or-dev-sda/25680)
  4. edk2 install failed to present a network address to the internet, wired connection not recognised by router.
  5. Docs for uboot at (https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-raspberry-pi4/#_installing_fcos_and_booting_via_u_boot) assume a non rpm-ostree install on the host machine. Ie there is no dnf available on my silverblue laptop, and I couldn't figure how to install using toolbox (perhaps I should have used a --privileged flag to podman). The docs for EDK (https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-raspberry-pi4/#_edk2_combined_fedora_coreos_edk2_firmware_disk), should probably invite the user to expand their xfs partition before mounting. In my experience, only gparted has the capacity to do this correctly without too much hassle.
  6. install on pi4b following instructions for edk2 at [fedora-docs](https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-raspberry-pi4/#_edk2_combined_disk_mode_alternate_machine_disk_preparation) - boot loads, after very long pause at grub boot screen 'booting coreos-vernum' , No IP address is shown, and SSH host key is displayed, 3 times, one for ecdsa, one for ed25519 and one for RSA.

  5. Busybox hello.service works as expected
  6. kernel.sysrq test works as expected, custom value of 0 remains after a reboot
  7. Setting systemd.unified_cgroup_hierarchy=0 in the Ignition config worked as expected: got a visible warning message on SSH login, /proc/cmdline indicates the kernel argument has been set. Rebooted the VM, settings persisted. Used rpm-ostree kargs to (1) update systemd.unified_cgroup_hierarchy to 1; (2) remove systemd.unified_cgroup_hierarchy; (3) add systemd.unified_cgroup_hierarchy=0. All changes were correctly registered after a reboot.
  8.
