[Opm] How to suppress message "Invalid MIT-MAGIC-COOKIE-1 key"

[Tsuyoshi Matsuura]

Hi Markus,

Thanks for the hint on the DISPLAY variable. It made me look in the 
right direction.

It seems the proprietary driver for the nvidia card in my setup was 
causing the problem. By changing the video driver from the proprietary 
nvidia driver to the Xorg one, the error message disappeared.

Best regards,

Tsuyoshi
