Re: Nvidia driver bypasses xorg.conf settings

Thank you, your mail made me check the changelog for nvidia-glx more carefully. I did this sloppily the first time as I never changed driver or kernel version and it worked before.

Adding 'Option "UseEdidFreqs" "no" ' to the device section in xorg.conf fixed my problem.

This information is in the NVIDIA_Changelog in /usr/share/doc/nvidia-glx/ . It says that UseEdidFreqs is now set to "on" by default.

I'm sorry to have bothered people with stuff that was actually documented :/.

Thanks for your help!

Well for LCD it does make sense yes. They don't flicker in the first
place at any speed.

Switching back to the older kernel doesn't help either. I don't think there's a problem with anything but the nvidia driver, since:

The nvidia driver has a tendancy to take the DDC data as above all. The
README file for the nvidia driver in /usr/share/doc/nvidia-glx/ should
say how you can force it to ignore DDC data.

Probably upgraded nvidia driver changed things.
