[gentoo-user] KDE won't start up....

[Andrew Lowe]

Hi all,
	I had a running KDE 4 setup and this afternoon did an:

emerge -NuD world

There were no errors reported, the kernel source had been updated, so I 
compiled the new kernel, and copied it into place, recompiled my nvidia 
driver and also evdev drivers and then rebooted the machine. Now, the 
machine boots up, I get all the usual booting messages, starting ntp, 
mounting drives, getting IP addresses, exporting nfs and so on, the 
screen goes black, the hour glass of the KDE log in screen briefly 
appears then the screen is blanked and I'm back at a text login.

	I've logged into the machine from the text login and recompiled the 
kernel, copied it into place, recompiled nvidia and evdev and still the 
problem persists. I've looked at the xorg & kdm logs and there are  a 
few errors there that google searches seem to say are OK. The thing that 
is confusing is that when at the text prompt, I can start up bog 
standard X via "startx" and the mouse and keyboard work but I can't get 
KDE to start. Does anyone have any ideas as to what could be causing 
this problem? Any thoughts on where, besides the two obvious logs, that 
I can try and track down what's going wrong here, or steps I can take to 
debug the KDE startup?

	Any thoughts greatly appreciated,

		Andrew
