** Description changed: This is an upstream issue-read the following bug reports. https://github.com/linuxmint/cinnamon/issues/9401 https://github.com/linuxmint/cinnamon/issues/9468 - I will shortly publish a patch/debdiff to allow for possible SRU. + An SRU patch is now available. This is a REGRESSION of a commit in Cinnamon 4.0.0 (https://github.com/linuxmint/muffin/commit/1d38120c9ded2578a14cb2e8bf46bb82b3acdc75) + + Debian Bug Patch: https://bugs.debian.org/cgi- + bin/bugreport.cgi?bug=965382 SRU TEMPLATE: [Impact] * In fallback mode Cinnamon/Muffin segfaults and makes the desktop unusable. * This would occur by having two monitors-a laptop and an external with the laptop off and the external on-supposedly with NVIDIA as a driver. [Test Case] * Upstream commits example to replicate bug: "Example to reproduce: Laptop monitor + external monitor. Arrange laptop monitor to the right of the external one. Using nvidia-450 (confirmed for me, at least), turn laptop monitor off. Ignoring horrible lag from driver, turn the laptop monitor back on (arranging it still to the right of the external monitor)." [Regression Potential] * Regressions manifesting is rather barely likely. Latest versions of Muffin patches this and so is upstream unstable have this patched. Regressions shouldn't be a threat unless: 1) Dependency problem 2) New versions of C causing incompatability problems or versions of Gobject-Introspection - * In the event of a regression, which is unlikely as of Aug 13 (UTC), + * In the event of a regression, which is unlikely as of Aug 13 (UTC), as Muffin's update would've been released a while ago (24 days), 2 days ago the version was bumped. A new upstream version would likely patch this problem aswell. * After 24 days it seems there is nothing to worry about regarding regressions but of course, always something to worry about. * It's been about enough time, nearly a month to spot any regressions from this fix. * This is actually a SOLVE of a regression * This regression fix goes back to Cinnamon 4.0.0-or when Eoan Ermine was released by getting refresh rates form xrandr * In upstream Mint this was an SRU/release as seen here: https://github.com/linuxmint/muffin/releases/tag/master.mint20 (The latest is the patch for this bug) - [Other Info] * I couldn't pbuilder-dist for some reason. Missing dependencies or stuff didn't exist-in sbuild it did though and my debuild -S did. * I will work on patching this in Groovy through debian unstable and will attach the bug report for groovy as part of this situation/regression.
