Problem: I installed Ubuntu Ultimate Edition 2.5 from Win7 EU. At startup Grub's only visible on Sony TV, LG monitor no longer worked. I entered the NVIDIA X Server Settings application, where I managed finally to set Sony TV = Disabled, but can not save it in the X configuration. With: sudo nvidia-settings, I look in the console:
VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.
Undefined Device "(null)" referenced by Screen "Default Screen".
Segmentation fault
Please help me solve the issue, it is unpleasant to switch on TV before using the PC.
Txk! C.D.
