Actually I finally get it working: ddcmon-i2c-1-50 Adapter: DDC:fb0 #0 on i2c-matroxfb Algorithm: Bit-shift algorithm Monitor ID: DEL635> Serial number: 959595606 Monitor Size (cm): 23x30 Vertical Sync (Hz): 0-0 Horizontal Sync (KHz): 0-0 I guess it had first being confused by the eeprom module I do load for the piix4 chipset I have also. One question comes to mind. The /etc/modules.conf file may contain references to i2c bus numbers (to ignore or force adresses). But the order in which the bus drivers are loaded (if there are more than one) has an importance there. So, am I right to assume that if the modules are not loaded in the correct order, the options lines will be bad? Is there a way to force a bus number for a given bus driver? (May I get the ddcmon specs for free somewhere?) -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
