KDM seems incredibly slow when starting.

English Install/Boot/Login
#1

After a fresh install of 12.3 KDM takes 30 seconds or longer before the login screen is shown. I have 12.3 installed on another machine that does not display this problem. I kept my old “home” folder, but formatted and replaced everything on the root partition. Both grub (legacy) and Plymouth seem to run normally. The delay seems to come when KDM starts. I have a standard KDM theme chosen; nothing custom. KDM and / or Kwin hang fairly often, from what I think are rapid mouse movements, but that may be a different problem.

There are a couple of warnings in the KDM log, which I do not understand. One in particular is the PCI address of my graphics card. The address in the error is not where the card is and xorg.conf shows the correct location. There are also D-bus errors. I have seen similar D-Bus errors in my last several versions of openSUSE. I almost always get them when I call amdccle, and often when I call konqueror super user. Again; possibly an unrelated error.

Graphics is a Radeon HD7870 running the latest ATI proprietary driver. Falling back to Radeon made no difference. Also, changing the login theme made no difference. CPUs are twin Opteron 290s, giving 4 cores at 2.8GHz. RAM is 12GB of DDR400 ECC registered Kingston server RAM.

Here is my KDM log (identical with each boot):

Here is my xorg.conf, although I don’t spot any problems:
