For example in Xorg.0.log ...
[ 15708.908] (WW)
And in the log files it states
[ 15708.905] Markers: (--) probed, (**) from config file, (==) default setting, (++) from command line, (!!) notice, (II) informational, (WW) warning, (EE) error, (NI) not implemented, (??) unknown.`
Is the first number the time?
Is there any literature on this subject? Or suggested ways to read through them and be able to make sense of them more fully?
