From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How new are you to Linux?* /gen
Have you checked the output of, say, “journalctl -b -2”? This would give you a system log of messages that go back to two boot sessions ago and normally show you what happened just before that first shutdown.
This could be drivers, background processes, hardware, no way to know without starting by looking at logs. Hell, I’ve had a monitor crash out my system multiple times and I wouldn’t have ever guessed if I didn’t check my logs and dmesg output.

First, sorry of the late response.
Second, running that command with the
-rparameter it returns this:Feb 13 17:24:45 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:24:45 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:24:45 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:24:45 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:24:33 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:24:33 [user]rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:23:31 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:23:31 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:22:46 [user] wpa_supplicant[957]: wlan0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-63 noise=999>Feb 13 17:22:34 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:22:34 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:22:08 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:22:08 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:21:24 [user] flatpak[9501]: (17:21:24) INFO: [Gog]: GOG presence setFeb 13 17:21:23 [user] flatpak[9501]: (17:21:23) INFO: [Gog]: Running command: GOGDL_CON>Feb 13 17:21:20 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:21:20 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:20:59 [user] wireplumber[1097]: wp-event-dispatcher: <WpAsyncEventHook:0x5be0f8feaff0> failed:>Feb 13 17:20:34 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:20:34 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:20:23 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:20:23 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:20:23 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.Feb 13 17:20:23 [user] rtkit-daemon[1064]: Supervising 10 threads of 6 processes of 1 users.lines 1-24FYI you can add
