Hi again. I have read the XFree86.0.log more carefully now and can see that the error message is a bit more informational, than at first glance: (==) I810(0): Write-combining range (0xf8000000,0x4000000) (II) I810(0): vgaHWGetIOBase: hwp->IOBase is 0x03d0, hwp->PIOOffset is 0x0000 (II) I810(0): Setting dot clock to 157.4 MHz [ 0x50 0x17 0x10 ] [ 82 25 1 ] (II) I810(0): chose watermark 0x22415000: (tab.freq 157.5) (WW) I810(0): xf86AllocateGARTMemory: allocation of 1024 pages failed (Cannot allocate memory) (II) I810(0): No physical memory available for 4194304 bytes of DCACHE (II) I810(0): Adding 0 scanlines for pixmap caching (EE) I810(0): Ring buffer allocation failed Could this have something to do with agpgart (which I don't really now what is) ? If you have a clue, please help or just give me some direction to look in. Thomas
