analog lcd monitor not working after installing a digital lcd monitor
I have a Samsung syncmaster 710N 17" analog lcd monitor. This was working fine with FC4. Then I got a new Dell 19" digital lcd monitor from my office. I installed FC5 on my machine. Everything was working fine. Now I have to revert back to the old samsung monitor. So I changed xorg.conf appropriately. This didnot work. The monitor displayed the following warning.
"Not Optimum Mode","Recommended Mode 1280 x 1024 60Hz"
The details about this can be found at
Something to do with operating frequency.
I thought it would be better if the monitor is detected at the installation time itself so I refromated the machine and installed FC5 again. It was able to detect my monitor and was also able to set the frequency range correctly but I still faced the same issue.
The x logs shows me a warning that no compatible modes were found so resorting to the default.
But actually none is shown.
I know where to set the frequency range in xorg.conf.
but where do you set that the oprating frequency must be 60. In some links I have seen something like 1280x1024-60 being specified in the modes but this didnot work too.
Does this have anything to do with the digital lcd that i once used? Do I need to configure dual monitor kind of stuff though there is actually just one monitor?
I have also tried updating to the latest kernel and the latest nvidia drivers but that didn't help.
I have an ASUS Geforce 6200 video card.
thanks and regards,
