Maybe it has grounded some previously unused wires in VGA connector, which are now used for I2C data & clock - but I thought that i2c subsystem will return error in this case (clock stuck on zero / data stuck on zero). > Strangely, the picture on the second head is stretched vertically - so I can't > see the top and bottom of the picture. Maybe 640x480 videomode constants for secondary head are not completely correct. I'll recheck them.

It is almost correct. 31.5kHz horizontal, 60Hz vertical, 640x480, 32bpp... Best regards, Petr Vandrovec vandrove@vc.cvut.cz
