I want to change the resolution from 640/480 to ANYTHING higher. I try to do it and it says the machine will restart and the wizard will begin after it boots up. It hangs with a black screen when it tries to boot up. Then i have to reset the machine and when it boots back up, no wizard. Can i change the xorg.conf and get it to work that way and not using the wizard. I have an nVidia 7300 GT card....i have read the 6 series cards are work....could the 7 series be the problem?
I had the similar issue - in my case it was happening because I had display connected to VGA, but the AVWizard somehow was outputting by default to DVI. Maybe you have the same issue: have you seen the following step: http://wiki.linuxmce.com/index.php/AVWizard_running_steps
- note the text If instead of AV Wizard you see black screen or "no signal" message on display, try to switch the connector type as it is described in section II
-- this will allow you to press number to specify connection type VGA, DVI etc. In my case, I pressed "2" to choose VGA and after couple of seconds blinking, the AVWizard restarted with outputting to VGA connector.
