Hi, I'm using nvidia-8756 driver on x86_64 computer. It seems that driver ignores modelines that set vertical refresh rate higher than 85Hz. I added some options in device section of xorg.conf file: Option "UseEDID" "false" Option "UseEDIDFreqs" "false" Option "ModeValidation" "NoEdidModes" but it didn't help... Are there any other options for the driver ? Ps. My monitor is Samsung syncmaster 959nf. -- Kazimieras <kazimieras.vaina@xxxxxxxxx>
