Comment 7 for bug 1310489

I have the same issue but on a Dell laptop, with NVIDIA GeForce GT 525M and Intel video card. On the Ubuntu 14.04 alpha and beta stages I didn't had any issue, but with the "stable" version xorg.conf is deleted after boot. Now I have some annoying behavior with my external monitor connected through HDMI.
The gpu-manager.log looks like this:
