Case s0lved!
There problem was xconsole in right bottom corner of loginscreen with message:
Code:
Console log for 'hostname'
It is not the KDM or the GDM that makes the xconsole appear...
It is XDM. This is solution for Red Hat distros:
As root open:
/etc/X11/xdm/Xsetup_0
It should look something like this:
Code:
#!/bin/sh
# $Xorg: Xsetup_0,v 1.3 2000/08/17 19:54:17 cpqbld Exp $
xconsole -geometry 480x130-0-0 -daemon -notify -verbose -fn fixed -exitOnFail
Just comment out the this line:
Code:
xconsole -geometry 480x130-0-0 -daemon -notify -verbose -fn fixed -exitOnFail
with
so it looks like this:
Code:
#xconsole -geometry 480x130-0-0 -daemon -notify -verbose -fn fixed -exitOnFail
Save the file... logout and no more xconsole....
I am not sure of this works on other distros....
