[gentoo-user] Icons at startup of a KDE session

[gentoo-user] Icons at startup of a KDE session

[Petric Frank]

Hello,

i've installed Gentoo and KDE 4.4 on an AMD64 system, configured 
/etc/conf.d/xdm to start kdm as login server.

After login the KDE4 desktop starts up - a little box with at least 5 or 6 
icons in it where one after the other icon displays blurred and then comes 
clear (Disk, Tools, World, ...).
This process stops at the fourth icon (after the world icon) which remains 
blurred. At this stage the PC simply hangs - no ssh, no VT-switch, nothing.

So my first question is - what stage the fourth icon stands for. And where to 
look for the issue.

After a reboot to the command line i viewed the logs (/var/log/messages, 
/var/log/Xorg.0.log) but nothing looks suspicious. The last line in 
/var/log/messages reads:
  <timestamp> <hostname> kdm: 0:[<pid>]: pam_unix(kde:session): session opened 
for  ...

The user was newly created using "useradd -m -g ...). There was no .kde4 
directory in his home directory.

Other window managers (fluxbox) don't show this problem.

Kernel is gentoo-sources-2.6.34-r1. All components are from the stable tree.

This may not be an gentoo problem.

All hints are welcome.

regards
  Petric

To be clear - it is not an 64 Bit OS, it is still x86.

Usually i add new users also to the plugdev group. As a test i removed the 
user from this group i got past the plash screen. Now the normal screen came 
up.

So it seems that the problem has something to do with the plugging system.

At which places i should throw an eye ?

I had weird effects when I had forgotten to set the sticky bit on /tmp.

ls wonko@weird ~ $ ls -ld /tmp
drwxrwxrwt 16 root root 4096 11. Aug 10:48 /tmp

If this  ^ t is missing, do a chmod +t /tmp, and try again.

Yes. There is at least 5 GBytes free.

It is starting if the user is not member of the group plugdev.

I thought - ok, if not plugdev then use policykit. I enabled this use-flag and 
re-build everything marked by this flag (emerge -uDN world).
But this does not help. I'm back to not being able to log in. :-(

That is a rather new direction. I never checked this.

same here - sticky bit set

It is there.
