Cannot Log into KDE anymore

Dear everybody,

I do not know if this is the right subsection, but anyway:

After trying out the ATI Catalyst driver (Using the catalyst-total package from AUR), I reinstalled the opensource driver.
However, now I cannot log into KDE anymore. The X-server seems to start correctly and I can enter my username and password
in KDM. Then from a moment the splashscreen from KDE appears and starts to load. But then the monitor blinks and I am back
at the login from KDM (the x-server does not seem to crash).

Any idea what could be the cause for this behaviour? Or if not, is there a log file where errors during the login-process into KDE
are saved?

Thanks in advance,
hermi

Hermi,

Have a look at ~/.xsession-errors, any pointers in there?

p.s. by the way, this is probably not kernel related

Re: Cannot Log into KDE anymore

Okay, this seems the right place to look at.

It says after "starting up...":
Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
kded(595): Communication problem with "kded", it probably crashed...
Error message was: "org.freedesktop.DBus.Error.NoReply": ""Message did not receive a reply (timeout by message bus)"".

startkde: Shutting down...
klauncher: Exiting on signal 1
startkde: Running shutdown scripts...
startkde: Done.

It seems to be a problem with dbus. Before the question arises: My system is up to date, so I have no idea where the problem
comes from.

Thanks in advance,
hermi

Try to reinstall libgl, xorg-server and xorg-server-common. Catalyst driver replaces some original libraries AFAIK.

And look into journalctl -b and systemctl.

The reinstallation did sadly not solve the problem.
And how do I look into journalctl? When I enter the command with "-b", nothing happens.

Are you using systemd?

Re: Cannot Log into KDE anymore

To be honest, I am not really sure. It is an older installation, but systemd is installed.
Although, I can still use commandos like "init 6", which do not work on an newer system
which was installed (on another computer) after the old initscripts were droped. I do get messages
at startup that my rc.conf is outdated.
Could this be the problem?

Re: Cannot Log into KDE anymore

Then it means you're not. I'm not sure if this is the issue, it can be. Anyway, you could try to look at /var/log/messages and /var/log/Xorg.0.log to solve this problem without reconstructing the whole system. xsession-errors unfortunately is not very helpful.
