** 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. This is a REGRESSION of a commit in Cinnamon 4.0.0 (https://github.com/linuxmint/muffin/commit/1d38120c9ded2578a14cb2e8bf46bb82b3acdc75) + + 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] + + * This is actually a SOLVE of a regression-I'd task this at medium + priority. + + * 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.
