I have just upgraded to KDE 4.2 today, using the Arch Linux pacman package manager, and out of five times, four times it locks up immediately after login, with something called "kres-migrator" running and starting Akonadi server, and then everything freezes

Any idea how to solve this problem?

I'm using archlinux on two machines and this problem didn't occur

Open Systemsettings -> Advanced Tab -> Akonadi configuration.

Does it report any Error?

On its second tab it has the possibility for a self test. Try to run that and post the test log.

Are you running any 3D effects? Additionally, does the Caps lock key still respond?

I have the same problem

it said just like this that "akonadi server can not regist on dbus".

after about 1 min , the mouse is active ,but no any panel on the desktop.
In output of ps can find the "plasma"

Assuming that you have no data in Akonadi, it would be safe to destroy its configuration and data files ( they could be corrupt )

Code: Select all

killall mysqld & killall akonadictl & killall akonadi_control & killall akonadiserver & rm -rf ~/.config/akonadi/ & rm -rf ~/.local/share/akonadi

Same problem, but I've noticed that turning off 3d acceleration the problem didn't occur.

This means it is probably unrelated to Akonadi.

All those affected: Distro + Graphics card please.

And for those having problems starting Akonadi server:
if you are running Kubuntu, check that the Akonadi Server Configuration (Systemsettings -> Advanced Tab -> Akonadi Configuration ->second tab) has the Kubuntu override executable mysqld-akonadi set.

We've had reports that it would still be mysqld and thus causing problems with Kubuntu's AppArmor Setup.

Kubuntu

nvidia geforce 8600GT

Same problem here.
"Akonadi control process not registered at D-Bus"
Distro ArchLinux+kdemod
Graphics = nvidia but no 3D. Composite enabled.

Luckily however, my system doesn't hand when this happens.

Self-test report follows...
Akonadi Server Self-Test Report

Test 2: SUCCESS
--------

MySQL server found.
Details: You currently have configured Akonadi to use the MySQL server '/usr/sbin/mysqld'.
Make sure you have the MySQL server installed, set the correct path and ensure you have the necessary read and execution rights on the server executable. The server executable is typically called 'mysqld', its locations varies depending on the distribution.

Test 3: SUCCESS

Test 8: SUCCESS
--------

akonadictl found and usable
Details: The program '/usr/bin/akonadictl' to control the Akonadi server was found and could be executed successfully.
Result:
Akonadi Control: stopped
Akonadi Server: stopped


Test 9: ERROR
--------

Akonadi control process not registered at D-Bus.
Details: The Akonadi control process is not registered at D-Bus which typically means it was not started or encountered a fatal error during startup.

Hmm, strange.

Is there probably more than one Akonadi version installed?

If you run qdbus in a terminal window, does it show any Akonadi processes?

If not, does

% akonadictl start

report errors?

Cheers,
_

The results of trying to start the akonadi service from the console gave me the clue. I got a message about starting the mysql deamon as root. Didn't I mention I was logged on as root?

Anyway, logging on as a regular user works fine. I can stop & start the service from the command line or from the System Settings application. I see org.freedesktop.Akonadi.Control and org.freedesktop.Akonadi in qdbus.

Thanks heaps!

Mark

and nepomunk too...
