Hello,
I did a dist-upgrade on a local machine. Because everything was fine with this I did dare to dist-upgrade another (this time a remote) machine, too. The DU was fine and I did reboot into the new kernel. (coming from 2.6.37.0.slh.4 this now is 2.6.37.0.slh.7)

Now I want to log in via kdm with x11vnc started remotely and krdc locally. Usually this does work. But now X just crashes before the first splashscreen icon appears and I am returned to the login screen.

As I do not now if this is just an issue with the remote vnc login or if it happens when trying to log in locally, too, I did not write this in the DU-Upgrade-Warning forum.

This is the content of the /var/log/kdm:

Does anybody have an idea what I could check or try?

I had such a problem a while ago already. But I thought that the x11vnc option "--reopen" did the trick. With this option the login did work again once. But it does not help now.

Greetings,

Oh, no, I do not understand this. Now it is working again. This is the same behaviour as the last time:

1) dist-upgrading the system

2) After reboot the login does not work, I am always returned to the login prompt of kdm again before the first splashscreen icon occurs.

3) I try the login multiple times with stopping, starting or restarting kdm. Nothing does help.

4) I am writing a post to the forum, asking for help.

5) I try the login for the last time before giving up. Not it does work!?

Can this be a timing problem? I thought it might be because maybe a mysql table check consumes much of the CPU power after reboot. But when I did check, I did not see the running process in top, so I think that this cannot be the reason.

Hmm. If someone still has a hint for me, this would be fine. Now I am glad that it works atm.

Bye,
arwa
