Is there a way to log all the stuff on start up to a text file so I can read it? It goes by way too fast! Mine shows some blue warnings but I can’t read them.
To be clear I mean the part that explains what is starting or failing, like if you hit [ESC] during start up or don’t have plymouth, not the plymouth splash screens.
If you open up a terminal and run the dmesg command, it should show up.
If you’d like it in a file, you can pipe it via standard shell features like so:
dmesg > boot.log
Thanks! Looks like this has even more info in it than the start up does for some reason, too.
Ah yeah, it’s all kernel messages since the start of the boot, so it won’t stop at the end of the boot process, but I also imagine the boot screen (Plymouth) only shows warning and error messages.
You can filter it to only show warnings and worse with:
dmesg --level=warn+
