Description Klaus Singvogel 2007-10-07 11:03:43 UTC

When starting openSUSE 10.3 booting happens as expected: graphical display.

But when the kdm starts, my display blanks, and according to the LEDs on my monitor, energy save is enabled. This happens at the same moment as kdm starts.

Having a blank display instead of the login manager confuses people, as they think that the machine has been crashed.

Did you try with xdm/gdm if this is kdm-specific?

Comment 9 Klaus Singvogel 2007-10-08 07:47:48 UTC

The bad news is, that it doesn't happen after every reboot. I noticed it now 2 times out of 4. Don't know why or what was different then.

BTW: How do I enable xdm/gdm (easily)?

> BTW: How do I enable xdm/gdm (easily)?

have xdm/gdm installed ;-), init 3, change DISPLAYMANAGER in /etc/sysconfig/displaymanager, init 5

Comment 11 Klaus Singvogel 2007-10-12 11:15:25 UTC

Ok, now I've new information:
- it happens in 50% of all cases
- it doesn't happen when the machine is already running:
  simple "init 3" "init 5" doesn't reproduce issue (regardless of kind of displaymanager)
- I'm not able to reproduce it when I _reboot_ the machine, a switch off is necessary
- it's not reproduceable, when the time of the switch off is short (= a few minutes)

Summarized: when doing above suggested test, I wasn't able to reproduce issue.

So I noticed it yesterday evening NOT, but early this morning. In both cases the kdm was configured.

There were no changes in the hardware since a long time. I spent 1GB of more memory last spring. Issue doesn't occur with SUSE 10.1, nor 10.2, first noticed when doing new installation of 10.3.

My current assumption regarding the cause of the problem is: the "nv" module, and that new checks at startup were made to acute. But I'm unsure regarding this.

Comment 12 Stefan Dirsch 2007-10-12 12:43:33 UTC

This looks again like Bug #302010 has not really been resolved. :-( 

I suggest to add kbd to Should-Start of earlyxdm and maybe even add sleeps in earlyxdm right before the exec of /etc/init.d/xdm in earlyxdm.

Comment 13 Klaus Singvogel 2007-10-15 07:43:29 UTC

YES!!! Thanks. After I added it and ran "insserv", it never happened again (did 4x boot of a "cold" machine).

As I said before: I cannot reproduce it properly (= not every boot), so there might be chances, that I was just lucky afterwards. But I don't think so.
