[SOLVED] startx fails - what's wrong?

I tried to install Xorg (and planned to install KDE too), but startx fails.

This is from Xorg.0.log:

I think nvidia would be better - I have been thinking of learning about GPGPU. (I understand X should not be running at the same time.)
Nouveau works with mu graphics card, but maybe I'd still use nvidia.

Thanks. I'll start finding out about the loaded driver. I wonder if it's nouveau. kernel module loaded at startup...

[edit]

Yes, there was nouveau that I couldn't rmmod, because "the kernel module is in use".
I also checked that the graphics drives should have been compiled to modules.
(Both nouveau and nv. are)

Neither nvidia nor nouveau is found in the /etc/conf.d/modules.
Where the heck could that nouveau get loaded?

I have found that you can't really have the nouveau and nvidia drivers co-exist. If you want to use the both drivers you will need to follow this guide:

http://wiki.gentoo.org/wiki/Nouveau_%26_nvidia-drivers_switching

You will need two kernels.

I thought the drivers could co-exist, but only one can be loaded.

How could I sort that out? Should I delete nouveau or move it?
Or should I figure out some udev-rule to exclude nouveau?
Or should I reconfigure+recompile the kernel?

I renamed the /lib/modules/3.12.21-gentoo-r1/kernel/drivers/gpu/drm/nouveau/nouveau.ko and rebooted.
Then I modprobed /usr/lib64/xorg/modules/drivers/nv_drv.so.
No errorrs were reported (but there didn't seem to be 'nv' or 'nvidia' in the output of lsmod.

Then I tried startx and got:

That seems ok. Did you set up an ~/.xinitrc file or are you booting using a DM such as gdm, kdm or whatever else?

If no WM grabs the server it will just run and exit.

Thanks, I guess that's what happened.
Shouldn't there be somet WM (by default) when one installs xorg-x11? Even if there is no DE?

I didn't check the xinitrc, though. I'll check.

There's no default WM since Xorg went modular.

Time ago, when you installed Xorg or XFree or whatever X under the sun you also got for free xterm, xclock, xfoobarmoocow... and then twm, which is the window manager that is shipped with X. But now you only get the pieces of X you need to run your concrete setup.

So, if you wanted a typical X session as we used to get in the past we need to emerge xterm, xclock and twm. The default session file seems to be still under /etc/X11/xinit/xinitrc if you want to take a look.

Since twm is not installed by default, you usually need to define your own ~/.xinitrc file and put a line like this on it (at the very least).

Thanks.
I'll emerge the pieces and figure out some .xinitrc (didn't have one in ~, but had a .Xauthority).

Truckload of thanks for all involved: openbox opened.
