After selecting 'Change resolution and sound' under advanced settings on a diskless MD, the computer reboots, but after running the helper script it stays in the console screen, blanking for a second once every 7 seconds. Has anyone else seen this? Is there a way to force the screen wizard to run without rebooting first?
We had this recently too. It turned out that there were two versions of the nvidia drivers loaded! Look in /var/log/Xorg.1.log to see if this is the case for you. Your should see some lines towards the end of the log that reflect that there are two nvidia drivers.
If the above is so try this... open a console session to the md in question and type;
sudo rmmod nvidia
If all is well you should find that your MD runs the AVwizard (you'll here a beep). Now you just need to use the number keys to select your output connector and resolution (if your not connected to the VGA connector that is).
Hope the above helps.
