Xorg log with KMS enabled.
I have a Westinghouse LCD and an x1900. When I use them together, I have to
run 'xrandr --output DVI-0 --set coherent_mode 0' to get the LCD to stop
blanking. It starts happening every 10 seconds and increases to the point
where it is constantly blanking.
However, if I run that command with KMS enabled, I get:
X Error of failed request: BadName (named color or f
Major opcode of failed request: 147 (RANDR)
Minor opcode of failed request: 11 (RRQueryOutputP
Serial number of failed request: 27
Current serial number in output stream: 27
The output of 'xrandr --props' is:
Screen 0: minimum 320 x 200, current 2560 x 1024, maximum 8192 x 8192
DVI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm

I can run 'xrandr --output DVI-0 --set mode 0' without any errors, and it does
change the value for coherent to 0, but it doesn't let the monitor work.
