[FIXED] frequency out of range

[Guest]

I have been running kubuntu 9. for about a year now perfectly and just recently installed the 10.04 upgrade. It appears to boot fine...shows the kubuntu splash screen but then it goes blank and my monitor displays an "Out of Freguency" Error. I have tried pressing esc as grub is loading to get into recovery mode. Once there I have run FailsafeX to reconfigure the graphics but it doesn't work. I have tried various things at the command prompt that I have found in other forums but most of the time the files and directories they reference don't even exist. I suspect they are referencing other versions of Linux or a different GUI.

I think this is going to require some file editing but I don't know where to start. There must be some way to lower the resolution or refresh rate from the command line isn't there?

Re: frequency out of range

"Frequency out of Range" is coming from the monitor itself. It means it is not receiving a valid signal from your graphics card/chip.

Use

lspci -vv

in a terminal window to learn the model of your GPU. Then you can search the forums for guidance on whether you need a framebuffer for the initial boot screens, and whether any special configuration of the video driver is needed.

Re: frequency out of range

I found a fix to this problem.

There was neither xorg.conf file in /etc/X11/ so I created one from one of the other xorg.conf. bak files and then edited the HorizSync and Vert Refresh lines so that they fell within the limits of my monitor.
