** 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. + * 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.

[Regression Potential] - * This is actually a SOLVE of a regression-I'd task this at medium - priority. + * Regressions manifesting is rather barely likely.
