[mythtv-users] nVidia driver 304.88: problems

[Jean-Yves Avenard]

To answer my problem...

Looking at the log, I could see that when I turned off my screen it
generated a xrandr even switching ti 1024x768 at 70Hz which isn't supported
by my monitor but is listed in the xrandr modes and is at the top of the
list.

Reading the nvidia X documentation, I found the following option:
Option "UseHotplugEvents" "boolean"

When this option is enabled, the NVIDIA X driver will generate RandR
display changed events when displays are plugged into or unplugged from an
NVIDIA GPU. Some desktop environments will listen for these events and
dynamically reconfigure the desktop when displays are added or removed.

Disabling this option suppresses the generation of these RandR events for
non-DisplayPort displays, i.e., ones connected via VGA, DVI, or HDMI.
Hotplug events cannot be suppressed for displays connected via DisplayPort.

Note that probing the display configuration (e.g. with xrandr or
nvidia-settings) may cause RandR display changed events to be generated,
regardless of whether this option is enabled or disabled. Additionally,
some VGA ports are incapable of hotplug detection: on such ports, the
addition or removal of displays can only be detected by re-probing the
display configuration.

Default: on. The driver will generate RandR events when displays are added
or removed.

Adding:
    Option        "UseHotplugEvents" "False"

to my device section:
problem solved...

Here is my xorg.conf that explicitely list the modelines I want and in the
order I want so myth find them more easily:
