nvidia-settings issue

[steinrotter]

Hi all,

I run Ubuntu Edgy with an MX4000 + XGL + Beryl. Everything works fine but Beryl is rather slow. Since a couple of days I like to get running nvidia-settings but it says:

ERROR: NV-CONTROL extension not found on this Display.


ERROR: Unable to determine number of NVIDIA GPUs on ':0.0'.


ERROR: Unable to determine number of NVIDIA Frame Lock Devices on ':0.0'.


ERROR: Unable to determine number of NVIDIA VCSCs on ':0.0'.



Also Yanc starts but shows an enpty screen.

I have installed the latest nVidia drivers via Envy.

Does somebody has any clues ?

Thank You ind advance,


Michael

`nvidia-settings` is communicating with the XGL X server, which doesn't support the NV-CONTROL extension; you will need to adjust your DISPLAY environment variable (or use the appropriate `nvidia-settings` command line option) to point to the X server that hosts XGL. Please note, however, that not all settings will take effect on the fly with this configuration. This is not a problem if Beryl is used with the GLX_ext_texture_from_pixmap extension.

Hi Zander,

thank You for Yr. reply. However, I am not a Linux expert and not familiar with environment variables...

root@michael:/home/michael# export $DISPLAY
bash: export: `:0.0': not a valid identifier

So i Guess the command to run nvidia-settings is

nvidia-settings -c 0:0.0 or something like tis ....?

How do I determine the correct display identifier ?


Yours,


Mic

Chances are the underlying X server is driving display :1.0, so you'd have to either use `DISPLAY=:1.0 nvidia-settings` or `nvidia-settings -c :1.0`.

Hi,

tried everything from :1.0 to 4.0 but no hope ...


Reply is always 'Cannot open display'

Is there any analytical method to determine what display identifier is assigned to X-server ?


Yours,
