During booting OS I have as the result stopping it at message:
"localname localhost [Ok]
_ "
Then I press [Ctrl]+[C] and have the messages that etc/rc.d/rc is open only for reading & that something wrong with /var/runlevel.dir

But the interesting thing is that sometimes OS boots without problems & sometimes I have such problem.

The another problem is that I make GUI by entering startx because sometimes my monitor switch off after loading GUI KDE.
I use notebook A7J.
What could you advise to me?
