Can you verify (with lspci -xxx) that PCI dword register 0x40 in matroxfb configuration space has not set bit 8 (it is lowest bit in register 0x41). 0=>disable legacy VGA, 1=>enable legacy VGA. Old Millennium I always responded to framebuffer accesses, and it was fixed in Millennium II. I thought that it was fixed in Mystique too. You can fix it with setpci, if matroxfb gets it wrong. > > Can you print DAC registers 0x4C,0x4D,0x4E,0x4F after this message? > > 0x4C..0x4E should contain 8,7E,3, and 0x4F should contain 0 when > > PLL is not locked, and 0x40 if PLL is locked. > > Ok, the code around the message now looks like this: > DAC register 4c=8 > DAC register 4d=7e > DAC register 4e=1f > DAC register 4f=0 Strange.
