KDE/nouveau screen: looks as if wrong resolution selected

X is installed and starts fine with TWM. I installed KDE and it starts fine with KDM. So far the screen looks fine. KDM starts loading the desktop but this seems much slower than before. (old install was also KDE but older version).

I get the background with the cashew in the upper right corner. No taskbar below, just a little grey square in the left lower corner.

If I hover over the cashew it opens a border but nothing filled only some garbled output left next to it. Going with the mouse over the place where the menus should be they appear one-by-one and disappear when I leave the spot where the menu should be.

About the same happens when I go to the lower left corner where the taskbar should be but it looks as if everything apprear left (off-screen) and I see only a border.

Right-click on the mouse gives a border without anything in it. That appears when I scroll through it but disappears as fast as I go over it.

Dmesg is too large to put in a post, I have put it in a file. Likewise the Xorg.0.log.

dmesg: http://users.skynet.be/sb262617/forum_gentoo/dmesg
Xorg.0.log: http://users.skynet.be/sb262617/forum_gentoo/Xorg.0.log

Only thing I see in dmegs that might be related is:

I think the problem may be the kernel version, I had to jump a kernel version because there was a regression of nouveau around the kernel version indicated in your dmesg information. I ended up with 3.18.3.

Worth a shot. Guess I'll have to recompile the Xorg server, drivers and kde to make sure?

Ok, got kernel 3.14.31 as this looks like that last stable one before 3.17.8-r1. Made an oldconfig, then emerge --newuse --deep for xorg-drivers, xorg-server and kdebase-meta.

After reboot into this kernel no change.

I get more and more the impression that Xorg is OK but the fault is with KDE. Is it possible to downgrade this?

Ok, emerged LXDE and this works without any problem AFAIK. So the issue is with KDE.
