10.04: /etc/x11/xorg.conf missing after reboot

[Oliver Schade]

Dear team,

just upgrade from Mythbuntu 9.04 to 10.04, all updates installed.

System: Intel SSD 160 GB for OS, 1.5 TB SATA for recordings, 4 GB RAM, Quad-Core, 2 DVB-S cards.
System was stable in 9.04 for a long time.

After installation of 10.04 I enabled propertiary Nvidia drivers to use VDPAU deinterlacer. nvidia-xconfig
creates a /etc/X11/xorg.conf which enables the Nvidia driver and works fine.

However after every second or third reboot the /etc/X11/xorg.conf file is gone. As VDPAU is configured
the system will not play TV or any recordings but boot into the "low-res" graphics setup.

Okay, first time I laughed and thought I did a mistake - recreated /etc/X11/xorg.conf. After the 10th time
I was quite frustrated.

I used chmod a-w xorg.conf and chmod a-w . in /etc/X11 to disable any updates. Since then it works fine.

I have reassigned this issue to nvidia-graphic-drivers for now. By the way, xorg.conf doesn't exists any more under Ubuntu Lucid because is auto configured.
