I am able to log into Ubuntu Wayland (20.04) but I am having a problem with regular Ubuntu. I have been advised to "read log files like dmesg or syslog".
My question is, if I run these in Wayland, will that help figure out what's going on in regular Ubuntu or do I have to log into regular Ubuntu in recovery mode and then read the log files in there?
(For context: my original post).
The logfiles of your system record what has been going on with your system, irrespective of the way you happen to log in (on a TTY, over SSH, in Gnome Shell, in xfce... So yes, inspection of your log files from within another session is relevant.
System log files are being stored for a certain time. By default, they are archived every 7 days. By default up to four cycles of these archives are preserved. So you can look back into the system logs for about the past month.
