Another thing I notice is that kwin is crashing and crashing and crashing. ps aux |grep kwin gives a new pid every time, no matter how fast I run it.
Could you try running kwin in gdb to get a backtrace of the crash?
How? I have a black screen and cannot <alt><f2>, <ctrl><alt><f1>, or <alt><shift><f12>. With x2go I can xfce, but when set x2go to KDE, again black screen. I've removed the last remaining fglrx GLX driver, and now kwin is not crashing anymore. Seems to hold the same PID for a good while. But still the black screen with (working) cursor.

Hello?
Sorry, this ticket escaped my radar. If this is still an issue, in particular with kwin crashing, could you please add a comment? Note that to get a backtrace from kwin, you can try the following: - start a different window manager, e.g. xfce, and open a terminal - in this terminal, run "gdb --args kwin --replace" - you will then hopefully get a crash, use "bt" to get the backtrace, and save to a file - restart xfce window manager to continue working. I guess without a backtrace, kwin developers cannot help.

But > still the black screen with (working) cursor. That would match the OP and indicate that kwin is up and compositing (Shift+Alt+F12 works?) but aparently neither plasma-desktop nor krunner are. This and esp. Debian Testing and even more the XFCE warnings about the failure to contact dbus would match http://forum.kde.org/viewtopic.php?f=66&t=120323 Is the the same or just an equal case (ie. are you "Quantum")?
I am Quantum. This plasma-desktop crash is caused by the USB driver not being able to handle some legacy devices. I had to unplug my Silverstone USB touchscreen in order to make KDE work.
Quoting Ben from forum.kde.org: "In this case, there is very little KDE could do to solve the issue. It is completely unexpected behaviour that system services such as UPower, UDisks, etc. will misbehave in such a manner. Future changes to the Solid interface to make it asynchronous would be the only way to fix it at the KDE level (I think there may be such plans as part of KDE Frameworks 5, but i'm not sure). The issue was caused because the XHCI driver problems caused those system services (UDisks, UPower) to become hung or crash, causing a kernel oops in the process. It is likely the card reader was a principal cause of this. As a result, KDE became hung awaiting their responses - in virtually all cases these services reply instantaneously, but this didn't occur in your case."
