[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

Anything in ~/.xsession-errors?

I wonder if KDE's {window manager|session manager} is failing out. I
don't know KDE very well, but that's what it sounds like.

.xsession-errors

Xorg.0.log

please. 
If both are huge, upload them somewhere.
Also make sure that the permissions of /tmp and /var/tmp are ok. Had it in the 
past that some update did some very scary things to both places.

Does startx give you the twm session with some xterms and an xclock?
If so, try running 'startkde' from an xterm.  (Or whatever may have
replaced startkde since I looked last.)

Running revdep-rebuild is a good idea after every update, too.

Also /var/log/kdm.log would be of use (if you are (well, want to ;)
using KDM as the login manager)... because it seems that the
problem might be with KDM greeter or something similar.

I had it segfaulting once, the symptoms were very similar,  KDM did
bring up X and start kdmgreet which crashed, X went down
immediately, because they had no clients, KDM noticed that X was
running only for a very short time and interpreted  that (correctly) as a
sign that something went wrong and didn't restart the X and insted just
stopped...

that would also explain why running startx works ...

btw, does 
startx /usr/bin/startkde 
start a KDE session?

Also the output from genlop -l --date yesterday so we know what you
emerged.

	revdep-rebuild is your friend!!!! I can remember kicking off the 
original emerge that caused my problem and thinking "I also need to 
remember to run revdep-rebuild when done" and then promptly forgot to do 
so. Thanks to walt's prompt, I've run it and things are now good.

	Also thanks to the others for kicking in with suggestions,

I prefer to emerge $( qlist -IC x11-drivers/ ), this makes sure all
relevant drivers are being re-compiled. Or emerge @x11-module-rebuild if
you are running the new portage.
But as you write there are no errors in Xorg.0.log, this cannot be your
problem.

Rename your .kde4 directory, or try to log in as another (new) user.
Let's see if this is a system-wide issue, or some KDE config screwup.
