After upgrade to Linux Mint 20.1, switched primary and secondary monitors [SOLVED]

[grndplane]

The upgrade has switched my primary and secondary monitors. When I drag them to the correct sides, and set primary monitor. I get GDB.Error:org.freedesktop.DBus.Error.ServiceUnkown: The name org.cinnamon.SettingsDaemon.XANDR_2 was not provided by any .service files

Sorry, thanks for putting it in the proper place. The problem was I had xrandr in my startup. It worked good for previous versions, but I guess it was fixing a problem that didn't exist in Mint 20.1.

If you are having a similar problem, worth noting that the startup application setting for Mint 20 has the csd-xrandr location in /usr/lib/x86_64-linux-gnu/cinnamon-settings-daemon while Mint 20.1 has the csd-xrandr file location in /usr/libexec.

If you edit the Cinnamon Settings Daemon - xrandr in the Startup Applications to point to the new location, this may fix the issue with ServiceUnknown error.

Thank you for looking into it. I deleted the xrandr from my startup, and on the next reboot it was recreated with the corrected path /usr/libexec/csd-xrandr that you mentioned. I guess not to many people had a problem.
