Black screen before login

Hi list.   I have some computers running Debian, and one of them (pentium 300mhz, 396 MB RAM), in the starting, before the desktop login appears, a black screen appears for 3 minutes. The hd doesn't work during this black screen. I tried other desktop (IceWm, blackbox) and the result is the same. Does anyone knows what could be wrong? In others list, a user of a pentium 200mhz said it's loaded instantly in that machine. Any information will be welcome.   My thanks in advance.  __________________________________________________Fale com seus amigos de graça com o novo Yahoo! Messenger http://br.messenger.yahoo.com/

Could be a DNS issue. What is the hostname of the machine which exhibits
the delay? Is there an entry for that name in /etc/hosts?

Don't think so. It is often advised to separate the hostname and
localhost in the above manner. The address 127.0.1.1 is a valid
address. But it's always worth a try, of course ...

huh. I won't argue the point as I don't know. But is it still a
loopback address? 'cuz if its not that could cause problems if some
process is looking for 'blaster' instead of 'localhost'. do please
educate me on that if you know.

Yes, it's a valid loopback address. Try pinging it ;-)

That looks OK.

The X server logs to /var/log/Xorg.0.log, while clients log to
~/.xsession-errors. You could try a 'tail -f' on those files in a
virtual console and see if you get a long pause at a particular line.

Sorry about my ignorance, some conventions I don't know well (yeat), but "virtual console" means a command line in Terminal?If it´s correct, I should do this:tail -f /var/log/Xorg.0.logThanks.Liam O'Toole <liam.p.otoole@gmail.com> escreveu: On Sat, 28 Apr 2007 08:41:57 -0300 (ART)Renato Gondim Filho wrote:> Yes, but the computer is not connected to the LAN.

What I am suggesting is that you try the following.

1. Switch to a virtual console using the key combination ctrl-alt-f1.
2. Login as root.
3. Issue the command '/etc/init.d/gdm restart && tail -f /var/log/Xorg.0.log'. Here I assume that GDM is your display manager.
4. The previous step will probably take you to the login screen (even though the login prompt hasn't appeared). If so, repeat step 1 to return to the virtual console.
5. Watch the progress of output as you follow the log file. Is there a point at which the output pauses for a long time?
6. You can toggle to the login screen at any time using ctrl-alt-f7.

Good luck.

Did you try ctrl-alt-f1 to return to the console from which you issued
the command?

Unfortunately, no. It is just a warning that the X server cannot use
ACPI for power management.

Ah, I see. Assuming you have not set the option 'DontVTSwitch' in
your /etc/X11/xorg.conf file, your X server is locking the keyboard
completely during this mysterious pause. Presumably the ability to
switch consoles returns after the login prompt, but by that time it is
not useful to you :-(

You mentioned before that the machine is not connected to the LAN, but
if you could connect it and start an SSH server, then you could login
remotely and monitor the log file from another machine.

Hopefully someone can advise you of other debugging options. It would
be helpful for example if you could find a way of telling the X server
to write time stamps to the log file.
