I now think the proposed gnome-shell version 3.30.1-2ubuntu1.18.10.1 is fine. It doesn't need fixing in itself but it does hit a mutter bug which needs fixing per the above link.
Since they would be released at different times anyway, and the secondary regression is probably already visible in disco, we may as well release the gnome-shell fix to cosmic now. The mutter fix is complete and will come soon (only waiting on upstream review). ** Tags removed: verification-failed verification-failed-cosmic ** Tags added: verification-done verification-done-cosmic -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1789356 Title: The wrong background flashes up briefly during the login animation since Yaru was introduced Status in gnome-shell package in Ubuntu: Fix Released Status in mutter package in Ubuntu: In Progress Status in gnome-shell source package in Cosmic: Fix Committed Status in mutter source package in Cosmic: Triaged Bug description: [Impact] The wrong background flashes up briefly (for a split second) during the login animation. The login screen and gnome-shell's system background are meant to be the same image so that the login procedure can VT switch without the user noticing. Then the final desktop expands over the system background. However it appears the login background and system background are not the same image any more, causing a visible glitch during login. [Test Case] 1. Install new version, logout 2. Log in into GDM -> Check that at login startup, the background matches GDM ones (same color, same gradient) 3. Logout, install gnome-session 4. Reboot so that GDM takes gnome-session into account 5. Select GNOME session and login -> At login startup, the background will matche the GNOME default one (from the lockscreen: grey noise), which matches GDM one if reset to default GNOME via update-alternatives. [Regression Potential] This code is loaded at session startup, if there is a syntax error, the session wouldn't start at all. This has been of course tested before committed (both on ubuntu and GNOME sessions) ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: yaru-theme-gnome-shell 18.10.2 ProcVersionSignature: Ubuntu 4.17.0-7.8-generic 4.17.12 Uname: Linux 4.17.0-7-generic x86_64 ApportVersion: 2.20.10-0ubuntu9 Architecture: amd64 Date: Tue Aug 28 14:19:48 2018 Dependencies: InstallationDate: Installed on 2018-05-26 (93 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Alpha amd64 (20180525) PackageArchitecture: all ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_AU.UTF-8 SHELL=/bin/bash SourcePackage: yaru-theme UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1789356/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
