Public bug reported:
Binary package hint: nvidia-settings
I have been trying to setup my computer to use nvidia twin view and I
can configure it just fine using nvidia-setting by hand. However if I
try to reload that configuration automatically (so I don't have to do it
by hand every boot), I get an error message.
$ nvidia-settings --load-config-only
ERROR: The attribute 'XVideoSyncToDisplay' specified on line 53 of
configuration file '/home/amp/.nvidia-settings-rc' cannot be assigned
the value of DFP-0 (the currently enabled display devices are DFP-1 on
magdalene:0.0).
The problem seems to be that the secondary must be enabled for "nvidia-
settings --load-config-only" to configure it. However when using the
nvidia-setting GUI by hand I can simply select the disabled display and
click configure and set it up. It seems that "nvidia-settings --load-
config-only" should be able to do this automatically.
It appears to me that there is information missing from .nvidia-
settings-rc. Maybe nvidia-settings is failing to save some settings to
the file. This is also shown by the fact that if I configure my displays
differently (to clone instead of be next to each other say) and then run
"nvidia-settings --load-config-only" the command does not print an error
but it also does not change the monitor layout.
This is especially a problem because nvidia-settings is unable to
generate a xorg.conf. So that there is no GUI way to configure twin view
so that it will presist through a logout/login cycle.
Attached are some config files that might be useful.
PS: This is related to bug #108060
