Hi, I've bought an IBM Thinkpad R32 with an ATI Radeon Mobility M6 LY (rev 0) card, which supports dual head (at least under the pre-installed Win XP) just fine.
I've successfully installed Debian/Woody with the experimental XFree86 4.2.1 packages. Now, I want to configure dual head operation with an external monitor under Linux. I've already read the Xinerama HOWTO and found a message on this list, that it should work with my card. If I understand things correctly, one has to put two devices with a different BusID into /etc/X11/XFree86-4. However, I only find one graphic-adapter on my pci-bus. Here is output of lspci: 00:00.0 Host bridge: Intel Corp. 82845 845 (Brookdale) Chipset Host Bridge (rev 04) 00:01.0 PCI bridge: Intel Corp. 82845 845 (Brookdale) Chipset AGP Bridge (rev 04) 00:1d.0 USB Controller: Intel Corp.: Unknown device 2482 (rev 02) 00:1d.1 USB Controller: Intel Corp.: Unknown device 2484 (rev 02) 00:1d.2 USB Controller: Intel Corp.: Unknown device 2487 (rev 02) 00:1e.0 PCI bridge: Intel Corp. 82820 820 (Camino 2) Chipset PCI (-M) (rev 42) 00:1f.0 ISA bridge: Intel Corp.: Unknown device 248c (rev 02) 00:1f.1 IDE interface: Intel Corp.: Unknown device 248a (rev 02) 00:1f.3 SMBus: Intel Corp.: Unknown device 2483 (rev 02) 00:1f.5 Multimedia audio controller: Intel Corp.

Is it correct, that for Xinerama, there would have to be a second VGA device in this listing? Or is there another way to set it up correctly? Are there perhaps any kernel/bios parameters that would result in another vga device popping up in the lspci listing? ciao Sebastian -- Sebastian Kanthak | [EMAIL PROTECTED]
