Ubuntu cinnamon display settings doesn't run

us flag

I'm working on Ubuntu 20.04 with Cinnamon 4.4.8 desktop. Some time ago I started to have issues with my displays: they either aren't detected or the layout is reset to default one. I tried to access display manager from settings from terminal. This is the output after selecting display manager:

cinnamon-settings
True
Using pam module (python3-pampy)
Loading Display module
**
CinnamonDesktop:ERROR:../libcinnamon-desktop/gnome-rr-config.c:666:gnome_rr_config_load_current: assertion failed: (gnome_rr_config_match (config, config))
Bail out! CinnamonDesktop:ERROR:../libcinnamon-desktop/gnome-rr-config.c:666:gnome_rr_config_load_current: assertion failed: (gnome_rr_config_match (config, config))
Aborted (core dumped)

Any hints how to fix it?

Have you tried to run `cinnamon-control-center` ? Please also update your question to add the following output `dpkg -l | grep -i cinnamon` .

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
