No, the X server will deactivate all video devices (it can see) which aren't claimed. And the fbdev driver can currently only claim the device it uses with the bus ID specified in the config file. > If there are multiple devices, and the one using offb maps to the first > frame buffer device, it should be possible to pass the frame buffer device > name to the X server for the other one (in the fbdev device option, > apparently).

The new code is very slim and mostly faster with HW acceleration, but not very optimized without yet (especially not on big endian :-/) . BTW this is about xc/programs/Xserver/fb , the author is Keith Packard <keithp@suse.com> . Michel ** Sent via the linuxppc-dev mail list.

I am working in fbdev support in the tdfx driver but its not ready yet and fbdev doesn't make this easy at all, for example if tdfxfb uses a hw cursor the fb memory you mmap starts at an offset and you have no way to know what this offset is, the xdriver *has* to know this to program the command fifo :( > > I set up two different monitors, two different "device" sections, and two > > different "screen" sections. > > Sounds good to me, but then I haven't tried Xinerama yet. > You also need to tell the xserver which screens to use, here is what i use Section "ServerLayout" Identifier "Main Layout" Screen "myScreen1" Screen "myScreen2" RightOf "myScreen1" InputDevice "Mouse1" "CorePointer" InputDevice "Keyboard1" "CoreKeyboard" EndSection > > > However, I read on here that fbdev has to have a bus ID to work, and there > > is none (that I'm aware of) on my internal video. > > Nothing about a video adapter in /proc/pci (or the output of lspci)? > If the internal video doesn't isn't in /proc/pci then you have no problem, the xserver won't detect the card so you can go away without the BusID line.
