I want to set non-plugable multiseat under fedora 17. i get the error " no valid EDID" on one of the two monitors. I get this Error on LG and SAMSUNG LCD monitors. Changing NVIIDA graphic card to ATI Radeon was of mo use. the other card is INTEL on board. Using kmod-Nvidia instead of NOUVEAU could neither solve the problem. After complete boot one of the monitor get dead though not completely black. Any suggestion?
