My h/w: Nvidia 7050 / 630a setup with a Sony KDL-26P3000E LCD TV. This TV supports 1024 X 768 X 60Hz and 1280 X 768 on the VGA port. While booting it shows the Kubuntu logo.
After having a Kubuntu 0704 base installation, and proving that the NVidia driver is working by changing resolution to 1280 X 768 and checking driver properties, I installed LinuxMCE 0704 from CD's. All went well, until the reboot, because after reboot, I see the Kubuntu logo, then during that picture, I hear a descending series of beeps (note, there was not an ascending series of beeps!) and then the signal to my TV goes out of sync, and that's it.
I can connect to the DCERouter setup web page, but as I have not run AVWizard successfully, there seems to be no way to tell this stupid wizard to not drive my LCD into a mode it does not support.
Pressing SHIFT during boot does not help, as I don't hear it monitoring it, and pressing 2,7, in sequence to force it to 1024 X 768 over the VGA port has no effect at all. I have now been battling with this for a week, so I thought it would be a good idea to ask for some help. Yes, I read this first http://wiki.linuxmce.org/index.php/AVWizard
Thanks for taking the time to explain how to get out of this maze.
