Created attachment 349338 [details] Not refreshed desktop background after moving a window with fallback mode After installing libX11-1.5.99.902 and libXau-1.0.8 I see strange effects. The desktop background is set to a green gradient, but only a black background is shown at the first system which is a Thinkpad T61, where Systems settings reports Gallium 04 on NV86. At the second system, Systems settings says Gallium 0.4 on NVD9 Fallback modus On. And here the desktop background is not refreshed.
BTW., At a system with Gallium 0.4 on NV94 everything is fine.
If I remove the fallback mode at NVD9 system (NVIDIA Corporation GF119 [GeForce GT 520]) the background is again refreshed. But the 3D mode as this card was not stable in the past. And I prefer the fallback mode, because it is for me much more ergonomic than the new 3D mode.
If I force the system with NV86 (NVIDIA Corporation G86M [Quadro NVS 140M]) into the fallback mode, I can't login into Gnome. I get "O No! Something goes wrong!" How can I switch of the forced fallback mode, if I can't login into ?
OK, with an intermediate cinnamon session I was able to switch off the forced fallback modus and I can again login into a gnome session. But background is still back in contrast to the settings.
If I don't use the fallback mode for the NVIDIA Corporation GF119 [GeForce GT 520] card x11 is still often crashing. At the last crash dmesg showed: ...

I will try the patches and report. If I understand http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=f33d4326ace73b1f0a2c66f474924919aff29267 correctly, the patches are kernel patches. What is the gentoo way to apply kernel patches?
You can apply the patch to the kernel source directory in /usr/src, or put it in /etc/portage/patches/sys-kernel/gentoo-sources where epatch_user can find it.

I used http://cgit.freedesktop.org/nouveau/linux-2.6/snapshot/linux-2.6-f33d4326ace73b1f0a2c66f474924919aff29267.tar.gz to install a linux-3.10.0-rc2. In the forced fallback mode I have the same problems as before, i.e. the gnome desktop background is not refreshed. So I am testing the 3D mode. Until now, for 30 minutes, the desktop is not yet crashed.

There's not really anything Gentoo developers can do to solve this. Please ping the upstream bug.
