When trying to use the xcalib tool to adjust the screens color and resolution such as...
xcalib -red 1.1 10.0 100.0
I get the error
Warning - Unable to read file ''
The error started after adding the xorg .conf file
Section "Device" Identifier "Intel Graphics" Driver "intel" EndSection
before adding this I was getting an error
Error-unsupported ramp size 0
