I'm using gentoo. Sometimes (not always), when the system starts (from power up), its crash (before I'm getting the GUI login window).I know Linux saves into log files the problem of the crash, but I'm so confuse and don't know from where to start ?Do I Need to check the dmsg file ? (or other log file ?)Do I need to grep with errors ? or there string pattern to search in the dmsg or other logging file ?)
How can I know what is the cause of linux to crash at start-up?
gentoo;crash
